How To Write a Bibliography (Plus Printable Guide With Examples)

Give credit where credit is due.

Writing a research paper involves a lot of work. Students need to consult a variety of sources to gather reliable information and ensure their points are well supported. Research papers include a bibliography, which can be a little tricky for students. Learn how to write a bibliography in multiple styles and find basic examples below.

Plus grab our printable Bibliography Guide for Students with examples from all three major style guides: APA (American Psychological Association), MLA (Modern Language Association), or The Chicago Manual of Style . Just fill out the form on this page to get the free guide.

IMPORTANT: Each style guide has its own very specific rules, and they often conflict with one another. Additionally, each type of reference material has many possible formats, depending on a variety of factors. The overviews shown here are meant to guide students in writing basic bibliographies, but this information is by no means complete. Students should always refer directly to the preferred style guide to ensure they’re using the most up-to-date formats and styles.

What is a bibliography?

When you’re researching a paper, you’ll likely consult a wide variety of sources. You may quote some of these directly in your work, summarize some of the points they make, or simply use them to further the knowledge you need to write your paper. Since these ideas are not your own, it’s vital to give credit to the authors who originally wrote them. This list of sources, organized alphabetically, is called a bibliography.

A bibliography should include all the materials you consulted in your research, even if you don’t quote directly from them in your paper. These resources could include (but aren’t limited to):

• Books and e-books
• Periodicals like magazines or newspapers
• Online articles or websites
• Primary source documents like letters or official records

Bibliography vs. References

These two terms are sometimes used interchangeably, but they actually have different meanings. As noted above, a bibliography includes all the materials you used while researching your paper, whether or not you quote from them or refer to them directly in your writing.

A list of references only includes the materials you cite throughout your work. You might use direct quotes or summarize the information for the reader. Either way, you must ensure you give credit to the original author or document. This section can be titled “List of Works Cited” or simply “References.”

Your teacher may specify whether you should include a bibliography or a reference list. If they don’t, consider choosing a bibliography to show all the works you used in researching your paper. This can help the reader see that your points are well supported and allow them to do further reading on their own if they’re interested.

Bibliography vs. Citations

Citations refer to direct quotations from a text that are woven into your own writing. There are a variety of ways to write citations, including footnotes and endnotes. These are generally shorter than the entries in a reference list or bibliography. Learn more about writing citations here.

What does a bibliography entry include?

Depending on the reference material, bibliography entries include a variety of information intended to help a reader locate the material if they want to refer to it themselves. These entries are listed in alphabetical order and may include: ADVERTISEMENT

• Author/s or creator/s
• Publication date
• Volume and issue numbers
• Publisher and publication city
• Website URL

These entries don’t generally need to include specific page numbers or locations within the work (except for print magazine or journal articles). That type of information is usually only needed in a footnote or endnote citation.

What are the different bibliography styles?

In most cases, writers use one of three major style guides: APA (American Psychological Association), MLA (Modern Language Association), or The Chicago Manual of Style . There are many others as well, but these three are the most common choices for K–12 students.

Many teachers will state their preference for one style guide over another. If they don’t, you can choose your own preferred style. However, you should also use that guide for your entire paper, following their recommendations for punctuation, grammar, and more. This will ensure you are consistent throughout.

Below, you’ll learn how to write a simple bibliography using each of the three major style guides. We’ve included details for books and e-books, periodicals, and electronic sources like websites and videos. If the reference material type you need to include isn’t shown here, refer directly to the style guide you’re using.

APA Style Bibliography and Examples

Technically, APA style calls for a list of references instead of a bibliography. If your teacher requires you to use the APA style guide , you can limit your reference list to only items you cite throughout your work.

How To Write a Bibliography (References) Using APA Style

Here are some general notes on writing an APA reference list:

• Title your bibliography section “References” and center the title on the top line of the page.
• Do not center your references; they should be left-aligned. For longer items, subsequent lines should use a hanging indent of 1/2 inch.
• Include all types of resources in the same list.
• Alphabetize your list by author or creator, last name first.
• Do not spell out the author/creator’s first or middle name—only use their initials.
• If there are multiple authors/creators, use an ampersand (&) before the final author/creator.
• Place the date in parentheses.
• Capitalize only the first word of the title and subtitle, unless the word would otherwise be capitalized (proper names, etc.).
• Italicize the titles of books, periodicals, and videos.
• For websites, include the full site information, including the http:// or https:// at the beginning.

Books and E-Books APA Bibliography Examples

For books, APA reference list entries use this format (only include the publisher’s website for e-books):

Last Name, First Initial. Middle Initial. (Publication date). Title with only first word capitalized (unless there’s a proper name/noun) . Publisher. Publisher’s website

• Wynn, S. (2020). City of London at war 1939–45 . Pen & Sword Military. https://www.pen-and-sword.co.uk/City-of-London-at-War-193945-Paperback/p/17299

Periodical APA Bibliography Examples

For journal or magazine articles, use the following format. If you viewed the article online, include the URL at the end of the citation.

Last Name, First Initial. Middle Initial. (Publication date). Title of article. Magazine or Journal Title (Volume number) Issue number, page numbers. URL

• Bell, A. (2009). Landscapes of fear: Wartime London, 1939–1945. Journal of British Studies (48) 1, 153–175. https://www.jstor.org/stable/25482966

Electronic APA Bibliography Examples

For articles with a specific author on a website, use this format:

Last Name, First Initial. Middle Initial. (Year, Month Date). Title . Site name. URL

• Wukovits, J. (2023, January 30). A World War II survivor recalls the London Blitz . British Heritage . https://britishheritage.com/history/world-war-ii-survivor-london-blitz

When an online article doesn’t include a specific author or date, list it like this:

Title . (Year, Month Date). Site name. Retrieved Month Date, Year, from URL

• Growing up in the Second World War . (n.d.). Imperial War Museums. Retrieved May 12, 2023, from https://www.iwm.org.uk/history/growing-up-in-the-second-world-war

When you need to list a YouTube video, use the name of the account that uploaded the video, and format it like this:

Name of Account. (Upload year, month day). Title [Video]. YouTube. URL

• War Stories. (2023, January 15). How did London survive the Blitz during WW2? Cities at war: London [Video]. YouTube. https://youtu.be/uwY6JlCvbxc

APA Bibliography (Reference List) Example Pages

MLA Style Bibliography Examples

MLA style calls for a Works Cited section, which includes all materials quoted or referred to in your paper. You may also include a Works Consulted section, including other reference sources you reviewed but didn’t directly cite. Together, these constitute a bibliography. If your teacher requests an MLA Style Guide bibliography, ask if you should include Works Consulted as well as Works Cited.

How To Write a Bibliography (Works Cited and Works Consulted) in MLA Style

For both MLA Works Cited and Works Consulted sections, use these general guidelines:

• Start your Works Cited list on a new page. If you include a Works Consulted list, start that on its own new page after the Works Cited section.
• Center the title (Works Cited or Works Consulted) in the middle of the line at the top of the page.
• Align the start of each source to the left margin, and use a hanging indent (1/2 inch) for the following lines of each source.
• Alphabetize your sources using the first word of the citation, usually the author’s last name.
• Include the author’s full name as listed, last name first.
• Capitalize titles using the standard MLA format.
• Leave off the http:// or https:// at the beginning of a URL.

Books and E-Books MLA Bibliography Examples

For books, MLA reference list entries use the following format. Add the URL at the end for e-books.

Last Name, First Name Middle Name. Title . Publisher, Date. URL

• Wynn, Stephen. City of London at War 1939–45 . Pen & Sword Military, 2020. www.pen-and-sword.co.uk/City-of-London-at-War-193945-Paperback/p/17299

Periodical MLA Bibliography Examples

Here’s the MLA-style format for magazines, journals, and newspapers. For online articles, add the URL at the end of the listing:

Harvard Style Bibliography | Format & Examples

Published on 1 May 2020 by Jack Caulfield . Revised on 7 November 2022.

In Harvard style , the bibliography or reference list provides full references for the sources you used in your writing.

• A reference list consists of entries corresponding to your in-text citations .
• A bibliography sometimes also lists sources that you consulted for background research, but did not cite in your text.

The two terms are sometimes used interchangeably. If in doubt about which to include, check with your instructor or department.

The information you include in a reference varies depending on the type of source, but it usually includes the author, date, and title of the work, followed by details of where it was published. You can automatically generate accurate references using our free reference generator:

Sources are alphabetised by author last name. The heading ‘Reference list’ or ‘Bibliography’ appears at the top.

Each new source appears on a new line, and when an entry for a single source extends onto a second line, a hanging indent is used:

Prevent plagiarism, run a free check.

Reference list or bibliography entries always start with the author’s last name and initial, the publication date and the title of the source. The other information required varies depending on the source type. Formats and examples for the most common source types are given below.

• Entire book
• Book chapter
• Translated book
• Edition of a book

Journal articles

• Print journal
• Online-only journal with DOI
• Online-only journal without DOI

• General web page
• Online article or blog
• Social media post

Newspapers and magazines

• Newspaper article
• Magazine article

When a source has up to three authors, list all of them in the order their names appear on the source. If there are four or more, give only the first name followed by ‘ et al. ’:

Sometimes a source won’t list all the information you need for your reference. Here’s what to do when you don’t know the publication date or author of a source.

Some online sources, as well as historical documents, may lack a clear publication date. In these cases, you can replace the date in the reference list entry with the words ‘no date’. With online sources, you still include an access date at the end:

When a source doesn’t list an author, you can often list a corporate source as an author instead, as with ‘Scribbr’ in the above example. When that’s not possible, begin the entry with the title instead of the author:

Though the terms are sometimes used interchangeably, there is a difference in meaning:

• A reference list only includes sources cited in the text – every entry corresponds to an in-text citation .
• A bibliography also includes other sources which were consulted during the research but not cited.

In Harvard referencing, up to three author names are included in an in-text citation or reference list entry. When there are four or more authors, include only the first, followed by ‘ et al. ’

In Harvard style referencing , to distinguish between two sources by the same author that were published in the same year, you add a different letter after the year for each source:

• (Smith, 2019a)
• (Smith, 2019b)

Add ‘a’ to the first one you cite, ‘b’ to the second, and so on. Do the same in your bibliography or reference list .

To create a hanging indent for your bibliography or reference list :

• Highlight all the entries
• Click on the arrow in the bottom-right corner of the ‘Paragraph’ tab in the top menu.
• In the pop-up window, under ‘Special’ in the ‘Indentation’ section, use the drop-down menu to select ‘Hanging’.
• Then close the window with ‘OK’.

How to Write a Bibliography for a Research Paper

Do not try to “wow” your instructor with a long bibliography when your instructor requests only a works cited page. It is tempting, after doing a lot of work to research a paper, to try to include summaries on each source as you write your paper so that your instructor appreciates how much work you did. That is a trap you want to avoid. MLA style, the one that is most commonly followed in high schools and university writing courses, dictates that you include only the works you actually cited in your paper—not all those that you used.

• If your assignment calls for a bibliography, list all the sources you consulted in your research.
• If your assignment calls for a works cited or references page, include only the sources you quote, summarize, paraphrase, or mention in your paper.
• If your works cited page includes a source that you did not cite in your paper, delete it.
• All in-text citations that you used at the end of quotations, summaries, and paraphrases to credit others for their ideas,words, and work must be accompanied by a cited reference in the bibliography or works cited. These references must include specific information about the source so that your readers can identify precisely where the information came from.The citation entries on a works cited page typically include the author’s name, the name of the article, the name of the publication, the name of the publisher (for books), where it was published (for books), and when it was published.

The good news is that you do not have to memorize all the many ways the works cited entries should be written. Numerous helpful style guides are available to show you the information that should be included, in what order it should appear, and how to format it. The format often differs according to the style guide you are using. The Modern Language Association (MLA) follows a particular style that is a bit different from APA (American Psychological Association) style, and both are somewhat different from the Chicago Manual of Style (CMS). Always ask your teacher which style you should use.

A bibliography usually appears at the end of a paper on its own separate page. All bibliography entries—books, periodicals, Web sites, and nontext sources such radio broadcasts—are listed together in alphabetical order. Books and articles are alphabetized by the author’s last name.

Most teachers suggest that you follow a standard style for listing different types of sources. If your teacher asks you to use a different form, however, follow his or her instructions. Take pride in your bibliography. It represents some of the most important work you’ve done for your research paper—and using proper form shows that you are a serious and careful researcher.

Bibliography Entry for a Book

A bibliography entry for a book begins with the author’s name, which is written in this order: last name, comma, first name, period. After the author’s name comes the title of the book. If you are handwriting your bibliography, underline each title. If you are working on a computer, put the book title in italicized type. Be sure to capitalize the words in the title correctly, exactly as they are written in the book itself. Following the title is the city where the book was published, followed by a colon, the name of the publisher, a comma, the date published, and a period. Here is an example:

Format : Author’s last name, first name. Book Title. Place of publication: publisher, date of publication.

• A book with one author : Hartz, Paula.  Abortion: A Doctor’s Perspective, a Woman’s Dilemma . New York: Donald I. Fine, Inc., 1992.
• A book with two or more authors : Landis, Jean M. and Rita J. Simon.  Intelligence: Nature or Nurture?  New York: HarperCollins, 1998.

Bibliography Entry for a Periodical

A bibliography entry for a periodical differs slightly in form from a bibliography entry for a book. For a magazine article, start with the author’s last name first, followed by a comma, then the first name and a period. Next, write the title of the article in quotation marks, and include a period (or other closing punctuation) inside the closing quotation mark. The title of the magazine is next, underlined or in italic type, depending on whether you are handwriting or using a computer, followed by a period. The date and year, followed by a colon and the pages on which the article appeared, come last. Here is an example:

Format:  Author’s last name, first name. “Title of the Article.” Magazine. Month and year of publication: page numbers.

• Article in a monthly magazine : Crowley, J.E.,T.E. Levitan and R.P. Quinn.“Seven Deadly Half-Truths About Women.”  Psychology Today  March 1978: 94–106.
• Article in a weekly magazine : Schwartz, Felice N.“Management,Women, and the New Facts of Life.”  Newsweek  20 July 2006: 21–22.
• Signed newspaper article : Ferraro, Susan. “In-law and Order: Finding Relative Calm.”  The Daily News  30 June 1998: 73.
• Unsigned newspaper article : “Beanie Babies May Be a Rotten Nest Egg.”  Chicago Tribune  21 June 2004: 12.

Bibliography Entry for a Web Site

For sources such as Web sites include the information a reader needs to find the source or to know where and when you found it. Always begin with the last name of the author, broadcaster, person you interviewed, and so on. Here is an example of a bibliography for a Web site:

Format : Author.“Document Title.” Publication or Web site title. Date of publication. Date of access.

Example : Dodman, Dr. Nicholas. “Dog-Human Communication.”  Pet Place . 10 November 2006.  23 January 2014 < http://www.petplace.com/dogs/dog-human-communication-2/page1.aspx >

After completing the bibliography you can breathe a huge sigh of relief and pat yourself on the back. You probably plan to turn in your work in printed or handwritten form, but you also may be making an oral presentation. However you plan to present your paper, do your best to show it in its best light. You’ve put a great deal of work and thought into this assignment, so you want your paper to look and sound its best. You’ve completed your research paper!

Sample Bibliography

An APA format bibliography lists all of the sources that might be used in a paper. A bibliography can be a great tool to help you keep track of information during the research and writing process. In some cases, your instructor may require you to include a bibliography as part of your assignment.

At a Glance

A well-written APA format bibliography can help you keep track of information and sources as you research and write your psychology paper. To create a bibliography, gather up all of the sources that you might use in your paper. Create an APA format reference for each source and then write a brief annotation. Your annotation should be a brief summary of what each reference is about. You can quickly refer to these annotations When writing your paper and determine which to include.

What Is an APA Format Bibliography?

An APA format bibliography is an alphabetical listing of all sources that might be used to write an academic paper, essay, article, or research paper—particularly work that is covering psychology or psychology-related topics. APA format is the official style of the American Psychological Association (APA). This format is used by many psychology professors, students, and researchers.

Even if it is not a required part of your assignment, writing a bibliography can help you keep track of your sources and make it much easier to create your final reference page in proper APA format.

Creating an APA Bibliography

A bibliography is similar in many ways to a reference section , but there are some important differences. While a reference section includes every source that was actually used in your paper, a bibliography may include sources that you considered using but may have dismissed because they were irrelevant or outdated.

Bibliographies can be a great way to keep track of information you might want to use in your paper and to organize the information that you find in different sources. The following are four steps you can follow to create your APA format bibliography.

Start on a New Page

Your working bibliography should be kept separate from the rest of your paper. Start it on a new page, with the title "Bibliography" centered at the top and in bold text. Some people use the title "References" instead, so it's best to check with your professor or instructor about which they prefer you to use.

Gather Your Sources

Compile all the sources you might possibly use in your paper. While you might not use all of these sources in your paper, having a complete list will make it easier later on when you prepare your reference section.

Gathering your sources can be particularly helpful when outlining and writing your paper.

By quickly glancing through your working bibliography, you will be able to get a better idea of which sources will be the most appropriate to support your thesis and main points.

Reference Each Source

Your references should be listed alphabetically by the author’s last name, and they should be double-spaced. The first line of each reference should be flush left, while each additional line of a single reference should be a few spaces to the right of the left margin, which is known as a hanging indent.

The format of each source is as follows for academic journals:

• Last name of first author (followed by their first initial)
• The year the source was published in parentheses
• The title of the source
• The journal that published the source (in italics)
• The volume number, if applicable (in italics)
• The issue number, if applicable
• Page numbers (in parentheses)
• The URL or "doi" in lowercase letters followed by a colon and the doi number, if applicable

The following examples are scholarly articles in academic journals, cited in APA format:

• Kulacaoglu, F., & Kose, S. (2018). Borderline personality disorder (BPD): In the midst of vulnerability, chaos, and awe.  Brain sciences ,  8 (11), 201. doi:10.3390/brainsci8110201
• Cattane, N., Rossi, R., & Lanfredi, M. (2017). Borderline personality disorder and childhood trauma: exploring the affected biological systems and mechanisms.  BMC Psychiatry,   18 (221). doi:10.1186/s12888-017-1383-2

Visit the American Psychological Association's website for more information on citing other types of sources including online media, audiovisual media, and more.

Create an Annotation for Each Source

Normally a bibliography contains only references' information, but in some cases you might decide to create an annotated bibliography. An annotation is a summary or evaluation of the source.

An annotation is a brief description of approximately 150 words describing the information in the source, your evaluation of its credibility, and how it pertains to your topic. Writing one of these for each piece of research will make your writing process faster and easier.

This step helpful in determining which sources to ultimately use in your paper. Your instructor may also require it as part of the assignment so they can assess your thought process and understanding of your topic.

Reasons to Write a Bibliography

One of the biggest reasons to create an APA format bibliography is simply to make the research and writing process easier.

If you do not have a comprehensive list of all of your references, you might find yourself scrambling to figure out where you found certain bits of information that you included in your paper.

A bibliography is also an important tool that your readers can use to access your sources.

While writing an annotated bibliography might not be required for your assignment, it can be a very useful step. The process of writing an annotation helps you learn more about your topic, develop a deeper understanding of the subject, and become better at evaluating various sources of information.

The following is an example of an APA format bibliography by the website EasyBib:

There are many online resources that demonstrate different formats of bibliographies, including the American Psychological Association website . Purdue University's Online Writing Lab also has examples of formatting an APA format bibliography.

Check out this video on their YouTube channel which provides detailed instructions on formatting an APA style bibliography in Microsoft Word.

You can check out the Purdue site for more information on writing an annotated APA bibliography as well.

What This Means For You

If you are taking a psychology class, you may be asked to create a bibliography as part of the research paper writing process. Even if your instructor does not expressly require a bibliography, creating one can be a helpful way to help structure your research and make the writing process more manageable.

For psychology majors , it can be helpful to save any bibliographies you have written throughout your studies so that you can refer back to them later when studying for exams or writing papers for other psychology courses.

How to Write a Bibliography (MLA, APA Examples)

Learn how to easily write a bibliography by following the format outlined in this article.

This resource will help your students properly cite different resources in the bibliography of a research paper, and how to format those citations, for books, encyclopedias, films, websites, and people.

What is a bibliography?

According to Infoplease.com, A bibliography is a list of the types of sources you used to get information for your report. It is included at the end of your report, on the last page (or last few pages).

What are the types of bibliography styles (MLA, APA, etc.)?

The 3 most common bibliography/citation styles are:

• MLA Style: The Modern Language Association works cited page style
• APA Style: The American Psychological Association style
• Chicago Style: The bibliography style defined by the Chicago Manual of Style

We’ll give examples of how to create bibliography entries in various styles further down in this article. 

What sources do you put in a bibliography?

An annotated bibliography should include a reference list of any sources you use in writing a research paper. Any printed sources from which you use a text citation, including books, websites, newspaper articles, journal articles, academic writing, online sources (such as PDFs), and magazines should be included in a reference list. In some cases, you may need or want to cite conversations or interviews, works of art, visual works such as movies, television shows, or documentaries - these (and many others) can also be included in a reference list.

How to get started writing your bibliography

You will find it easier to prepare your MLA, APA, or Chicago annotated bibliography if you keep track of each book, encyclopedia, journal article, webpage or online source you use as you are reading and taking notes. Start a preliminary, or draft, bibliography by listing on a separate sheet of paper all your sources. Note down the full title, author’s last name, place of publication, web address, publisher, and date of publication for each source.

Harvard Guide to Using Sources 

• The Honor Code
• Bibliography

If you are using Chicago style footnotes or endnotes, you should include a bibliography at the end of your paper that provides complete citation information for all of the sources you cite in your paper. Bibliography entries are formatted differently from notes. For bibliography entries, you list the sources alphabetically by last name, so you will list the last name of the author or creator first in each entry. You should single-space within a bibliography entry and double-space between them. When an entry goes longer than one line, use a hanging indent of .5 inches for subsequent lines. Here’s a link to a sample bibliography that shows layout and spacing . You can find a sample of note format here .

Complete note vs. shortened note

Here’s an example of a complete note and a shortened version of a note for a book:

1. Karen Ho, Liquidated: An Ethnography of Wall Street (Durham: Duke University Press, 2009), 27-35.

1. Karen Ho, Liquidated , 27-35.

Note vs. Bibliography entry

The bibliography entry that corresponds with each note is very similar to the longer version of the note, except that the author’s last and first name are reversed in the bibliography entry. To see differences between note and bibliography entries for different types of sources, check this section of the Chicago Manual of Style .

For Liquidated , the bibliography entry would look like this:

Ho, Karen, Liquidated: An Ethnography of Wall Street . Durham: Duke University Press, 2009.

Citing a source with two or three authors

If you are citing a source with two or three authors, list their names in your note in the order they appear in the original source. In the bibliography, invert only the name of the first author and use “and” before the last named author.

1. Melissa Borja and Jacob Gibson, “Internationalism with Evangelical Characteristics: The Case of Evangelical Responses to Southeast Asian Refugees,” The Review of Faith & International Affairs 17, no. 3 (2019): 80-81, https://doi.org/10.1080/15570274.2019.1643983 .

Shortened note:

1. Borja and Gibson, “Internationalism with Evangelical Characteristics,” 80-81.

Bibliography:

Citing a source with more than three authors

If you are citing a source with more than three authors, include all of them in the bibliography, but only include the first one in the note, followed by et al. ( et al. is the shortened form of the Latin et alia , which means “and others”).

1. Justine M. Nagurney, et al., “Risk Factors for Disability After Emergency Department Discharge in Older Adults,” Academic Emergency Medicine 27, no. 12 (2020): 1271.

Citing a book consulted online

If you are citing a book you consulted online, you should include a URL, DOI, or the name of the database where you found the book.

1. Karen Ho, Liquidated: An Ethnography of Wall Street (Durham: Duke University Press, 2009), 27-35, https://doi-org.ezp-prod1.hul.harvard.edu/10.1215/9780822391371 .

Citing an e-book consulted outside of a database

If you are citing an e-book that you accessed outside of a database, you should indicate the format. If you read the book in a format without fixed page numbers (like Kindle, for example), you should not include the page numbers that you saw as you read. Instead, include chapter or section numbers, if possible.

How to write a bibliography

Published March 26, 2021. Updated June 2, 2022.

Bibliography definition

A bibliography is defined as a list of sources written on a particular subject or by a specific author.

Overview of how to write a bibliography

All sources should be appropriately cited both within the text and in the references. The word “bibliography” refers both to reference lists in general and to a list specific to Chicago/Turabian style. Depending on the discipline and paper guidelines, it should be formatted in MLA, APA, or Chicago/Turabian style. An online tool or an official style guide can be used to properly cite the references.

Worried about your writing? Submit your paper for a Chegg Writing essay check , or for an Expert Check proofreading . Both can help you find and fix potential writing issues.

Pick the right citation style

There are three main styles for formatting your essay: MLA, APA, and Chicago/Turabian. Your choice will depend on your teacher, assignment, or discipline. For student papers, consult your teacher or department if you are unsure which to use. If submitting to an academic journal, you should check the guidelines for submission.

Bibliography v. Works Cited v. References

“Bibliography” is both the generic term for a list of sources and the term for the Chicago/Turabian end citations.

The main difference between the two is that a Chicago bibliography lists all works used in writing the paper, both works cited and works consulted. On the other hand, MLA and APA use reference lists instead of bibliographies, which only list works directly cited within the body of the paper. An MLA reference list is headed “Works Cited.” An APA list is headed “References.”

Resources available

When crafting your bibliography, use a manual or style guide. Even if you’ve memorized the basic formatting and most common entries, you may want to look up the format for less common source types.

Naming authors in MLA citations

If there is only one author, write the full name: Last name, First name. If there are two authors, list them in the order they appear on the book cover with only the first inverted. If there are three or more authors, list only the first, followed by the Latin phrase “et al.”

Book citation

In general, an MLA citation for a book follows this format:

Last Name, First Name. Book Title . Publisher City*, Publisher, Publication Year.

Norgren, Jill. Belva Lockwood: The Woman Who Would Be President . New York University Press, 2008.

*Note the absence of the city of publication. In MLA style, only include it to differentiate between a publisher’s different offices or if the book was published before 1900.

Article citation

In general, an MLA citation for a periodical follows this format:

Author(s). “Article Title.” Periodical Name , Publication date, pages.

If you found the article online or in an online database, you will need to include that information. Use the DOI number if available. If you cannot find it, use a stable URL.

You should also cite the volume and issue number if applicable.

Grossberg, Michael. “Who Gets the Child? Custody, Guardianship, and the Rise of a Judicial Patriarchy in Nineteenth-Century America.” Feminist Studies , vol. 9, no. 2, 1983, pp. 235–260. JSTOR , www.jstor.org/stable/3177489.

Because the amount and type of information available can vary so dramatically, the citations for websites can also look quite different from one another. The basic format is

Author (if known). “Webpage Name.”  Website Name . Publisher, Date published (if known), URL or DOI, Date accessed (if applicable).

The following citation is for a blog entry on the Women at the Center website published by the New York Historical Society and Library:

Mogulescu, Laura. “Eliza Webster’s Seneca Village and 19th-Century Black Life in NYC.” Women at the Center , New York Historical Society Museum & Library, 17 Feb. 2021, womenatthecenter.nyhistory.org/eliza-websters-seneca-village-and-19th-century-black-life-in-nyc/.

Sample Works Cited page

The following provides an example of an MLA reference list with several different kinds of entries.

Works Cited

Harmon, Amy, and Danielle Ivory. “Fight Over Health Conditions and Vaccine Eligibility Emerges in US.” New York Times , 9 Mar. 2021, p. A1.

McAllister, Ward. “A Glimpse of High Society.” Empire City: New York Through the Centuries , edited by Kenneth T. Jackson and David S. Dunbar, Columbia University Press, 2002, pp. 356–361.

APA style is the second most commonly used citation style for student papers and the most used in academic publishing.

An APA reference list accompanies a paper with in-line parenthetical citations. Unlike MLA, APA cites the date of the source rather than the page of the material referenced: (Author, date).

The general formatting for an APA reference page resembles an MLA Works Cited page.

Naming and alphabetizing authors in APA citations

Write each author’s last name, as well as their first and middle initial. Unlike in MLA citations, list all authors up to (and including) twenty. If there are more than twenty authors, use an ellipsis after the first nineteen and end with the final author.

Alphabetize reference entries by the author’s last name. However, if there is more than one work by the same author, arrange those entries chronologically, beginning with the oldest and ending with the most recent.

Capitalizing titles

Instead of using title case, only capitalize proper nouns, the first word of the title, and the first word after a colon and a dash if applicable.

APA distinguishes between academic journals and other kinds of sources. Because of this, journal titles are the only exception to the above rule. Capitalize all major words.

The general APA format for citing a book is

Last Name, First Initial. Middle Initial. (Publication Year). Book title . Publisher.  

Norgren, J. (2008). Belva Lockwood: The woman who would be president . New York University Press.

Scholarly journal article citation

The general APA format for citing an article in a journal is

Last Name, First Initial. Middle Initial. (Publication Year). Article title. Journal Name, volume (issue), pages. DOI or URL

Use the DOI number if available. If you cannot find it, use a stable URL

Website citation

The general APA format for citing a website is

Chicago/Turabian Style

Chicago style is most commonly used for published works. Turabian style is a modified version of Chicago style for higher-level student papers.

Chicago-style papers can either use a parenthetical citation that greatly resembles APA style citation, or they can use foot or endnotes and a bibliography.

A Chicago bibliography often lists works consulted, as well as works cited.

Begin on a new page after the last page of your essay. Keep the same one-inch margins, header, and page number format as the rest of the text.

Unlike MLA and APA reference lists, the entries have half-inch hanging indents but are single-spaced. Leave an extra line between entries.

At the top of the page, center the word “Bibliography” (not in quotation marks). Leave two lines between this heading and your first entry.

Naming authors in Chicago citations

In footnotes, cite up to three. Use “et al.” if there are more than three. In the bibliography, list up to ten authors.

If you list more than one work by the same author, only write out the author’s name for the first one. Thereafter, use three m-dashes: —.

The basic Chicago format for a book is

Last name, First name.  Title . Place of publication: Publisher, Year of publication.

Unlike in MLA style, provide the place of publication for all entries.

Norgren, Jill. Belva Lockwood: The Woman Who Would Be President . New York: New York University Press, 2008.

Scholarly Journal Article citation

The basic Chicago format for an article is

Last name, First name. “Article title.” Journal Name Volume, Issue (Publication date): pages. DOI or URL.

The basic Chicago format for webpage citation is

Last Name, First Name. “Webpage title.” Website Name. Publisher Publication or revision date. Access date if no other date is available. URL.

How to Write an Annotated Bibliography, With Examples

An annotated bibliography is a type of bibliography that includes a comment by the author about the source in addition to the source’s publishing information. The author’s notes, or annotations, can discuss anything relevant to the topic, such as the source’s accuracy, the context in which it was written, or even your personal views on the source.

Annotated bibliographies are sometimes a requirement in assignments, so it’s a good idea to learn their rules. Below, we explain how to write an annotated bibliography in APA, MLA, and Chicago formats. We even include an annotated bibliography example for each.

What is an annotated bibliography?

Annotated bibliographies are a type of bibliography with notes from the author on each source. These notes are called “annotations” and generally run around 50–150 words . The notes themselves have a very specific format, depending on the style guide used, as explained below.

What do annotated bibliography notes talk about?

Annotations in bibliographies can discuss anything relevant to the paper’s or book’s topic or give context to the reader so they can better understand the source. There are no formal restrictions on what annotations can be about, but in general, they usually fall into these categories:

• a brief overview of the source
• the background of the source’s author
• context about how or why the source was written
• the accuracy of the source
• any biases the source shows
• anything the source doesn’t address
• elements of the source that are particularly useful, like graphs or charts
• your personal views on the source

How to cite sources in an annotated bibliography

Annotated bibliographies cite their sources the same way as any other type of bibliography , including a works cited page or reference list . Simply follow the standard rules for whatever format you’re using when writing the full citation.

If you need help, Grammarly’s auto-citation feature can automatically create a citation if you’re using one of the ten most popular online source websites: Wikipedia, Frontiers, PLOS One, ScienceDirect, SAGE Journals, PubMed, Elsevier, DOAJ, arXiv, or Springer. Otherwise, feel free to use our free citation generator to create a full citation in whatever style you need.

How to write an annotated bibliography in APA, MLA, and Chicago

How to write an annotated bibliography in apa.

Annotated bibliographies in APA follow the same rules for page margins, font, and line spacing as other pages in the APA format , which you can find in the link.

The annotations for an annotated bibliography in APA, however, follow specific formatting rules:

• Annotations appear underneath the source they refer to.
• Use an indentation of 0.5 inches from the left margin (1.5 inches from the edge of the page) for all lines of the annotation, just like a block quote.
• The first line of an annotation does not get indented any further; use the same indentation as the other lines.
• If the annotation spans more than one paragraph, use an extra indentation of 0.5 inches (2 inches from the edge of the page) for the first line of any paragraphs after the first. Again, this follows the same format as block quotes.
• Sources are organized in alphabetical order by the creator’s surname, or last name (which comes first in citation entries).

How to write an annotated bibliography in MLA

The MLA format offers guidelines on both the formatting and content of annotations:

• Annotations should “describe or evaluate sources.” They should not discuss minor details, cite evidence, quote the source, or re-list the points in the source’s argument.
• Annotations can be written in either complete or incomplete sentences.
• Place annotations underneath the citation.
• Indent your annotation an additional 1 inch from the start of the entry (2 inches from the edge of the page). This differentiates it from the citation’s first indent (1 inch from the edge of the page) and its hanging indent (1.5 inches from the edge of the page).
• If the annotation spans more than one paragraph, use an extra indentation of 0.5 inches (2.5 inches from the edge of the page) for the first line of any paragraphs after the first.
• Title the page either “Annotated Bibliography” or “Annotated List of Works Cited.”
• You can choose whether to organize sources by the subject, date of publication, or alphabetically by author or title.

How to write an annotated bibliography in Chicago

Because the Chicago format is designed to be flexible, its rules for annotated bibliographies are more open-ended than the other formats. Here are the guidelines for how to write an annotated bibliography in Chicago style:

• If annotations are short and/or not included for every source, you can place annotations in brackets directly after the full citation, on the same line. If annotations are more detailed, start them on a new line underneath the full citation.
• Each line of an annotation is indented an additional 0.5 inches from the start of the entry (1.5 inches from the edge of the page). It should be equal to the hanging indent of the full citation.
• Annotated bibliographies may contain an author’s note at the top of the page. This should provide context about why the author chose these sources or how the page is organized.

Annotated bibliography examples

Annotated bibliography example for apa.

Diamond, J. (1997). Guns, Germs, and Steel: The Fates of Human Societies . W. W. Norton & Company. This book, which won the Pulitzer Prize, attempts to answer the question of why some civilizations succeeded while others faded away into history. Author Jared Diamond emphasizes the environmental and geographical influences on a civilization as factors for success, more than a civilization’s culture or race. While this book proves scientifically that race is inconsequential in the success of a civilization, critics accuse Diamond of reducing the whole of human history down to “environmental determinism.”

Author Jared Diamond emphasizes the environmental and geographical influences on a civilization as factors for success, more than a civilization’s culture or race. While this book proves scientifically that race is inconsequential in the success of a civilization, critics accuse Diamond of reducing the whole of human history down to “environmental determinism.”

Annotated bibliography FAQs

An annotated bibliography is a type of bibliography that includes a comment by the author about each source in addition to the source’s publishing information. The author’s notes, or annotations, discuss anything about the source that’s relevant to the topic, such as its accuracy, bias, or the context in which it was written.

How does it differ from a regular bibliography?

Just like other bibliographies, annotated bibliographies list the sources cited in the work, along with their publishing details. The difference is that annotated bibliographies also include notes from the author with extra information, whereas regular bibliographies do not.

How is an annotated bibliography structured?

The structure of annotated bibliographies depends on the formatting style: APA, MLA, or Chicago. Although each style has its own formatting rules, in general, the annotation comes after the full citation and is often indented in the same manner as block quotes.

APA Format is the official writing style of the American Psychological Association, and is primarily used in subjects such as psychology, education, and the social sciences.

It specifies how to format academic papers and citations for publication in journals, periodicals, and bulletins.

This guide will show you how to prepare and format a document to be fully compliant with APA Format in 2020.

Before You Start Writing...

There are several steps you must take to prepare a new document for APA style before you start writing your paper:

• Make sure the paper size is 8.5" x 11" (known as 'Letter' in most word processors).
• Set the margin size to 1" on all sides (2.54cm).
• Change the line spacing to double-spaced .
• Add page numbers to the top-right corner of every page.
• Add a running head to the top-left corner of every page.

How to Cite Sources | Citation Generator & Quick Guide

Citing your sources is essential in  academic writing . Whenever you quote or paraphrase a source (such as a book, article, or webpage), you have to include a  citation crediting the original author.

Failing to properly cite your sources counts as plagiarism , since you’re presenting someone else’s ideas as if they were your own.

The most commonly used citation styles are APA and MLA. The free Scribbr Citation Generator is the quickest way to cite sources in these styles. Simply enter the URL, DOI, or title, and we’ll generate an accurate, correctly formatted citation.

Citation examples and full guides, frequently asked questions about citing sources.

Citations are required in all types of academic texts. They are needed for several reasons:

• To avoid plagiarism by indicating when you’re taking information from another source
• To give proper credit to the author of that source
• To allow the reader to consult your sources for themselves

A citation is needed whenever you integrate a source into your writing. This usually means quoting or paraphrasing:

• To quote a source , copy a short piece of text word for word and put it inside quotation marks .
• To paraphrase a source , put the text into your own words. It’s important that the paraphrase is not too close to the original wording. You can use the paraphrasing tool if you don’t want to do this manually.

Citations are needed whether you quote or paraphrase, and whatever type of source you use. As well as citing scholarly sources like books and journal articles, don’t forget to include citations for any other sources you use for ideas, examples, or evidence. That includes websites, YouTube videos , and lectures .

Discover proofreading & editing

Usually, your institution (or the journal you’re submitting to) will require you to follow a specific citation style, so check your guidelines or ask your instructor.

In some cases, you may have to choose a citation style for yourself. Make sure to pick one style and use it consistently:

• APA Style is widely used in the social sciences and beyond.
• MLA style is common in the humanities.
• Chicago notes and bibliography , common in the humanities
• Chicago author-date , used in the (social) sciences
• There are many other citation styles for different disciplines.

If in doubt, check with your instructor or read other papers from your field of study to see what style they follow.

In most styles, your citations consist of:

• Brief in-text citations at the relevant points in the text
• A reference list or bibliography containing full information on all the sources you’ve cited

In-text citations most commonly take the form of parenthetical citations featuring the last name of the source’s author and its year of publication (aka author-date citations).

An alternative to this type of in-text citation is the system used in numerical citation styles , where a number is inserted into the text, corresponding to an entry in a numbered reference list.

There are also note citation styles , where you place your citations in either footnotes or endnotes . Since they’re not embedded in the text itself, these citations can provide more detail and sometimes aren’t accompanied by a full reference list or bibliography.

A reference list (aka “Bibliography” or “Works Cited,” depending on the style) is where you provide full information on each of the sources you’ve cited in the text. It appears at the end of your paper, usually with a hanging indent applied to each entry.

The information included in reference entries is broadly similar, whatever citation style you’re using. For each source, you’ll typically include the:

• Author name
• Publication date
• Container (e.g., the book an essay was published in, the journal an article appeared in)
• Location (e.g., a URL or DOI , or sometimes a physical location)

The exact information included varies depending on the source type and the citation style. The order in which the information appears, and how you format it (e.g., capitalization, use of italics) also varies.

Most commonly, the entries in your reference list are alphabetized by author name. This allows the reader to easily find the relevant entry based on the author name in your in-text citation.

In numerical citation styles, the entries in your reference list are numbered, usually based on the order in which you cite them. The reader finds the right entry based on the number that appears in the text.

Because each style has many small differences regarding things like italicization, capitalization , and punctuation , it can be difficult to get every detail right. Using a citation generator can save you a lot of time and effort.

Scribbr offers citation generators for both APA and MLA style. Both are quick, easy to use, and 100% free, with no ads and no registration required.

Just input a URL or DOI or add the source details manually, and the generator will automatically produce an in-text citation and reference entry in the correct format. You can save your reference list as you go and download it when you’re done, and even add annotations for an annotated bibliography .

Once you’ve prepared your citations, you might still be unsure if they’re correct and if you’ve used them appropriately in your text. This is where Scribbr’s other citation tools and services may come in handy:

Add a citation whenever you quote , paraphrase , or summarize information or ideas from a source. You should also give full source details in a bibliography or reference list at the end of your text.

The exact format of your citations depends on which citation style you are instructed to use. The most common styles are APA , MLA , and Chicago .

The abbreviation “ et al. ” (Latin for “and others”) is used to shorten citations of sources with multiple authors.

“Et al.” is used in APA in-text citations of sources with 3+ authors, e.g. (Smith et al., 2019). It is not used in APA reference entries .

Use “et al.” for 3+ authors in MLA in-text citations and Works Cited entries.

Use “et al.” for 4+ authors in a Chicago in-text citation , and for 10+ authors in a Chicago bibliography entry.

The Scribbr Citation Generator is developed using the open-source Citation Style Language (CSL) project and Frank Bennett’s citeproc-js . It’s the same technology used by dozens of other popular citation tools, including Mendeley and Zotero.

You can find all the citation styles and locales used in the Scribbr Citation Generator in our publicly accessible repository on Github .

APA format is widely used by professionals, researchers, and students in the social and behavioral sciences, including fields like education, psychology, and business.

Be sure to check the guidelines of your university or the journal you want to be published in to double-check which style you should be using.

MLA Style  is the second most used citation style (after APA ). It is mainly used by students and researchers in humanities fields such as literature, languages, and philosophy.

What is a Bibliography?

What is an annotated bibliography, introduction to the annotated bibliography.

• Writing Center
• Writer's Reference Center
• Helpful Tutorials
• the authors' names
• the titles of the works
• the names and locations of the companies that published your copies of the sources
• the dates your copies were published
• the page numbers of your sources (if they are part of multi-source volumes)

Ok, so what's an Annotated Bibliography?

An annotated bibliography is the same as a bibliography with one important difference: in an annotated bibliography, the bibliographic information is followed by a brief description of the content, quality, and usefulness of the source. For more, see the section at the bottom of this page.

What are Footnotes?

Footnotes are notes placed at the bottom of a page. They cite references or comment on a designated part of the text above it. For example, say you want to add an interesting comment to a sentence you have written, but the comment is not directly related to the argument of your paragraph. In this case, you could add the symbol for a footnote. Then, at the bottom of the page you could reprint the symbol and insert your comment. Here is an example:

This is an illustration of a footnote. 1 The number “1” at the end of the previous sentence corresponds with the note below. See how it fits in the body of the text? 1 At the bottom of the page you can insert your comments about the sentence preceding the footnote.

When your reader comes across the footnote in the main text of your paper, he or she could look down at your comments right away, or else continue reading the paragraph and read your comments at the end. Because this makes it convenient for your reader, most citation styles require that you use either footnotes or endnotes in your paper. Some, however, allow you to make parenthetical references (author, date) in the body of your work.

Footnotes are not just for interesting comments, however. Sometimes they simply refer to relevant sources -- they let your reader know where certain material came from, or where they can look for other sources on the subject. To decide whether you should cite your sources in footnotes or in the body of your paper, you should ask your instructor or see our section on citation styles.

Where does the little footnote mark go?

Whenever possible, put the footnote at the end of a sentence, immediately following the period or whatever punctuation mark completes that sentence. Skip two spaces after the footnote before you begin the next sentence. If you must include the footnote in the middle of a sentence for the sake of clarity, or because the sentence has more than one footnote (try to avoid this!), try to put it at the end of the most relevant phrase, after a comma or other punctuation mark. Otherwise, put it right at the end of the most relevant word. If the footnote is not at the end of a sentence, skip only one space after it.

What's the difference between Footnotes and Endnotes?

The only real difference is placement -- footnotes appear at the bottom of the relevant page, while endnotes all appear at the end of your document. If you want your reader to read your notes right away, footnotes are more likely to get your reader's attention. Endnotes, on the other hand, are less intrusive and will not interrupt the flow of your paper.

If I cite sources in the Footnotes (or Endnotes), how's that different from a Bibliography?

Sometimes you may be asked to include these -- especially if you have used a parenthetical style of citation. A "works cited" page is a list of all the works from which you have borrowed material. Your reader may find this more convenient than footnotes or endnotes because he or she will not have to wade through all of the comments and other information in order to see the sources from which you drew your material. A "works consulted" page is a complement to a "works cited" page, listing all of the works you used, whether they were useful or not.

Isn't a "works consulted" page the same as a "bibliography," then?

Well, yes. The title is different because "works consulted" pages are meant to complement "works cited" pages, and bibliographies may list other relevant sources in addition to those mentioned in footnotes or endnotes. Choosing to title your bibliography "Works Consulted" or "Selected Bibliography" may help specify the relevance of the sources listed.

The Importance of an Annotated Bibliography

An Annotated Bibliography is a collection of annotated citations. These annotations contain your executive notes on a source. Use the annotated bibliography to help remind you of later of the important parts of an article or book. Putting the effort into making good notes will pay dividends when it comes to writing a paper!

Good Summary

Being an executive summary, the annotated citation should be fairly brief, usually no more than one page, double spaced.

• Focus on summarizing the source in your own words.
• Avoid direct quotations from the source, at least those longer than a few words. However, if you do quote, remember to use quotation marks. You don't want to forget later on what is your own summary and what is a direct quotation!
• If an author uses a particular term or phrase that is important to the article, use that phrase within quotation marks. Remember that whenever you quote, you must explain the meaning and context of the quoted word or text. 

Common Elements of an Annotated Citation

• Summary of an Article or Book's thesis or most important points (Usually two to four sentences)
• Summary of a source's methodological approach. That is, what is the source? How does it go about proving its point(s)? Is it mostly opinion based? If it is a scholarly source, describe the research method (study, etc.) that the author used. (Usually two to five sentences)
• Your own notes and observations on the source beyond the summary. Include your initial analysis here. For example, how will you use this source? Perhaps you would write something like, "I will use this source to support my point about . . . "

How to Write a Bibliography

In this post

A bibliography is nothing more than a written list of your sources, outlining everything you used in the creation of the work, even if you didn’t cite it directly. This is something that almost all students will be asked to compile and add to their works at some point. Bibliographies are generally used in academic documents and from a student’s point of view they are most commonly used within your undergraduate or master’s dissertation. But what does a bibliography actually look like? When is a bibliography used? And how do you create a bibliography for your essay or research paper? Here’s everything you need to know about how to write a bibliography:

What is a Bibliography?

For many students creating a bibliography can be a daunting prospect, and part of the reason for this is that many students aren’t sure what a bibliography is. The good news is that a bibliography is much simpler than it sounds. A bibliography is nothing more than a list of all of the sources that you have used to help you write an essay or other extensive document. This includes not only the sources that you have directly quoted or referred to in your essay but also any works that you have read throughout your research for the piece. Even if a work is not cited directly, if you have read it as part of your essay preparation, or if your essay has otherwise been influenced by the work then it should be included and cited in your bibliography.

Bibliographies are commonly used in academic documents , such as at the end of an undergraduate or master’s level dissertation. But brief and less formal versions of bibliographies can also be used at the end of a journalistic piece, presentation, or video to lend them legitimacy and to visibly demonstrate that they have been well-researched. But academia is the main focus of the bibliography. So, if you’re thinking of pursuing further education and studying at degree level then it’s important that you understand what a bibliography is and how to create one. If an undergraduate essay or dissertation doesn’t include a properly cited and formatted bibliography, then it isn’t completed. As the way students access information has changed, so too has the information that you can include in your bibliography. Traditionally these were lists of books, essays and articles, but now websites, videos, and other multimedia sources should be cited in your bibliography too if they are accessed as part of your research.

There are many benefits of using a bibliography. These include:

• Demonstrating to your tutor, instructor, or anyone else assessing your essay that you have conducted the necessary research for your assignment and that you know how to put together a robust and comprehensive bibliography.
• Crediting the authors of any source materials that you have based your piece on for the research that they have conducted, ensuring that your piece does not appear plagiarised because all source materials used in your piece have been fully cited.
• Finally, as well as benefitting the authors you have cited and your tutor, the primary reason a bibliography should be included in your work is to benefit your readers. It will make it much easier for them to find the sources you have cited, read those works themselves, and conduct their own research on the same topic too. Bibliographies play an essential role in sharing knowledge and advancing understanding of a subject.

When is a Bibliography Used?

We have established that bibliographic information is descriptive information about a piece of work. Now we need to assess when we will need this bibliographic information: when is a bibliography used? Bibliographies are generally used in a wide range of academic research projects and disciplines. Secondary school students, college students and distance learning students, university students and postgraduate students may all be required to create bibliographies in their academic works. The bibliography in a research paper or project is typically one of the last pages of the paper adding to the piece after your own content but before any appendices.

The terms bibliography, references and cited works are often used interchangeably, but these three are actually unique ways of referencing your work and your sources. A “Works Cited” list is an alphabetical list of works cited or sources you specifically called out while composing your paper. This differs from a bibliography because you don’t need to include any additional sources that you have read or that may have otherwise influenced your piece in a works cited list. As a general rule, this means that works cited lists are much shorter than bibliographies. Reference lists are very similar to works cited lists, but they are written in APA (American Psychological Association) format, whilst bibliographies often use the Harvard referencing system . Reference lists are arranged alphabetically by the author’s last name. Whilst cited works and reference lists are similar, bibliographies are very different. A bibliography should list all the material you have consulted in preparing your essay, whether you have actually referred to and cited the work or not. So even if you only read a page or two or a text, and don’t directly reference it in your work, it should still be included in your bibliography. For this reason, bibliographies include longer references and are significant blocks of text.

Primary and Secondary Sources

The sources that you will cite within your academic works fall into two main categories: primary sources and secondary sources. But students often have difficulty differentiating between the two. However, the differences between primary sources and secondary sources are easy to work out. If you are quoting a first-hand account of something, or an original work, then this is a primary source.

Some examples of primary sources include: news articles, photographs, autobiographies, novels and short stories, letters and diary entries, and original works of art. From a multimedia point of view, documentaries, radio broadcasts and podcasts, and recordings of music or speeches are also considered to be primary sources. Working with a primary source means that you examine the source material, analyse it, and then reach your own conclusions. If you read a novel and then write an essay about its themes, for example, then you are using the novel as your primary source and you draw your own conclusions from it. In science-based subjects, any research or data you gather for yourself, by conducting your own studies or research, is considered to be a primary source. But if you are analysing data that has been gathered by someone else then this is then considered to be a secondary source. This example is important because it demonstrates that primary sources don’t always have to be documents you have created yourself: if you’re taking raw data that has been produced by someone else then this is still considered a primary source.

Secondary sources differ from primary sources because they are further removed from them. If a piece of art is the primary source, for example, then an essay analysing that piece of art would be considered to be a secondary source. Other examples of secondary sources include: textbooks that discuss other concepts, theories, or source material, biographies written about other famous figures, works written by critics or other academics and key political commentary. In short, a primary source provides direct access to material which you can then discuss and analyse, whilst a secondary source requires you to look at the material through the lens of another person or another point of view. If you are reading another critic’s analysis of a work, then their perspective is likely to have some influence on your critical approach or opinion. For this reason, many academics believe primary sources to be more reliable than secondary sources. But that is a one-dimensional approach: working with secondary sources can be beneficial because it allows you to understand how others perceive the work you are discussing. It also provides a clear insight into the cultural perspective that surrounds the work.

Types of Bibliography

There is no singular type of bibliography: different kinds of academic work require different kinds of bibliography, and they are each laid out and formatted slightly differently. Some of the main types of bibliography that you need to be aware of include:

• Analytical bibliography. This is a bibliography that analyses the route that a work makes from its initial manuscript stage to publication. When creating an analytical bibliography you should not only detail the high-level information about a cited source, such as the title and the name of the author, but also more specific details about the work, such as its number of pages, any illustrations it includes, and even the type of binding it is held together with.
• Annotated bibliography. As the name suggests, this type of bibliography includes annotations. An annotation is a short note that concisely and clearly explains why you chose each of your sources. Each annotation included within an annotated bibliography is usually just a few sentences long but will provide your readers with valuable insight into your view of the source. Although they are similar to literature review bibliographies, annotated bibliographies do not discuss how the research is conducted in the same level of depth.
• National bibliography. Source material is categorised into groups depending on where they were published, or the time period in which they were published. Often texts in a national bibliography are organised by region or nation.
• Personal bibliography. If you have included a range of pieces in your essay that are unpublished works, or hard-to-find works, then a personal bibliography is the best way to list these. This type of bibliography is best used for academic pieces that focus on multiple works by the same author: biographically focused pieces, for example.
• Corporate bibliography. As the name implies, a corporate bibliography will group sources in relation to specific organisations or corporations.
• Subject bibliography. Finally, sources within subject bibliographies are grouped depending on which subjects they cover. Generally, these bibliographies list primary and secondary sources, which makes them more in-depth. Other bibliographies on this list may not always outline both primary and secondary sources in this way.

Information Required from Print Sources

All of the bibliographic material that you will need from print sources can be found on their title page. The information that you will need to include in your citation will depend on the type of bibliography that you are compiling, but regardless of what citation style is being used, there are key pieces of information that you will always need to collect in order to create the citation in a bibliography. This information is:

• The name of the author you are citing.
• The title of the publication you are citing.
• Article title (if using a journal or magazine article).
• The volume number of the journal, magazine or encyclopaedia you are citing, or the edition you are citing in the case of a printed publication.
• Date of publication.
• Place of publication.
• Page number(s) relevant to your research, and that you are citing within your work.

Information Required from Web Sources

The way in which you will cite a website or other web sources differs from the way in which you would cite a traditional printed text. The way in which you will cite a web source will depend on whether you are citing an online article or a web page. In the case of a web article, you will need to share:

• The author and/or editor name of the web piece that you are citing.
• The title of the website that you are citing.
• Company or organisation that owns or posts to the website.
• URL (website address).
• The date that you accessed the information you are citing and, where possible, the date that the information you are citing was originally published.

How to write a bibliography essay: a step-by-step guide

There are three main approaches that you need to follow if you want to cope with the task yourself:

• A brief story;
• A thorough analysis;
• A complete library research.

Start with noting down or taking photos of the books, documents, other papers or any other resources that you have on the list. You will have plenty at the end to choose from. You will use these notes and photos to express your thoughts the right way.

There are two major types of the style that you can use in your academic papers: APA or MLA It’s good to find out which one you have to use before you start as you will spend much time trying to correct everything. The difference between the styles is in the position of the name of the author, book title, the publishing year and so on. The format for the annotation is one for both styles. The length of the annotation can be from one sentence to a few pages. The best way to find out how much you need to write is to ask you professor.

Don’t rush and think critically regarding the information that is presented in the book or the article. The process of evaluation is the following:

• You like it or not;
• You get the core message of the book or not;
• The information is related to the topic or not;
• The information is reliable or not;
• There are phrases or sentences for citations or not;
• There are any evaluation reviews for this source or not;
• You can find out the author’s credentials or not;
• The source is upt-date or not;
• Your professor approves this source or not.

Start writing your bibliography essay with a summary of the book. Think of the main ideas, arguments and topics that are described in the source. Ask yourself what this very source is about and think how would you answer to someone else. Think if it provides any value for people. Mention why you have chosen this source and if the information in it is reliable. Write how this source is related to the topic of your research and add a few words how it helped you to research the topic.

It’s an obvious step but there are many students that ignore it. The thing here is that you should be pretty much attentive to every period, coma, bracket or any other punctuation mark that you are using. The bibliography can be short and easy for revising. But if you have a list of 50 sources with long annotations, you will need a few days for proofreading.

You won’t be able to use any software. You will need to check every single detail especially if it’s your first try. Once you think that the job is done, take a nap or rest a while and come back to proofreading again. We recommend you to do at least three checks with some rest in between. This will make your brain notice even the slightest drawbacks.

It’s better to take this step before you write your own text or when you feel you’ve run out of ideas. You can see the style and you can see the way someone has crafted the annotation. Keep in mind that the bibliography for essay differs from the one in dissertation. Take a look at the structure of the annotation, what comes first and how the author expresses personal position. Of course, you can find some bad samples that will guide you to the wrong way, so don’t treat all the samples to be examples to follow.

Most of the students feel unsure about the value of their own work. Of course, you can choose the annotated bibliography writing service to assist you, but let’s talk about the evaluation of your own work. The first thing to do is reading your annotation as if you were someone else. Read aloud and record your reading. Ask anyone from your friends to listen to your reading. If you think that everything is awful, have some rest and show your annotation to your professor. And you will surely know what to do next.

Whether you are tackling formal essay writing or writing an undergraduate or master's dissertation, many students find it daunting the first time they are required to write a bibliography at the end of a piece of work. Fear not – not only is it much less complicated and scary than you might think, but we have compiled a list of the most important basic pointers on how to write a bibliography. Read on to get on your way to the best dissertation bibliography…

What is a bibliography?

A bibliography is more simple than it sounds. It is a list, usually at the end of an undergraduate or master's dissertation , of all the sources you have used to help you write the essay. This includes both the sources you may have referred to or quoted already in the essay and also any further works you read whilst preparing or researching the essay, even if you didn’t specifically cite them.

Using a separate line for each new text listed, simply write out the details of each of your texts in the following order: Author (surname, initials), year of publication, title of book (in italics or underlined), edition (if there have been more than one), publisher, place of publication. For example:

Jones, AK, 2004, The Artists of Antiquity , 2nd edition, Virago, London

Writing a bibliography: primary and secondary sources

If you are writing a dissertation on a particular author or poet, you may want (or be required) to divide your bibliography into primary and secondary sources. In this case, works by the author himself that have formed the basis of the texts you have studied are primary sources, whilst critical reference books or other material are secondary sources. For example, in a dissertation on Austen, Pride and Prejudice would be a primary source, whilst Austen’s narrative voice: A companion would be a secondary source.

Bibliography styles: Harvard and others

There are several different accepted styles of bibliography, which have slight variations on the information included and the order in which it is presented . The method described above is a standard, widely accepted format, but when you are writing a bibliography make sure you check exactly what stylistic requirements are stipulated by the University or course provider. Remember, one of the most important tips on how to write a bibliography is to remain consistent – whatever method you choose, stick to it throughout and keep the style the same for every reference.

Style and Grammar Guidelines

APA Style provides a foundation for effective scholarly communication because it helps writers present their ideas in a clear, concise, and inclusive manner. When style works best, ideas flow logically, sources are credited appropriately, and papers are organized predictably. People are described using language that affirms their worth and dignity. Authors plan for ethical compliance and report critical details of their research protocol to allow readers to evaluate findings and other researchers to potentially replicate the studies. Tables and figures present information in an engaging, readable manner.

The style and grammar guidelines pages present information about APA Style as described in the Publication Manual of the American Psychological Association, Seventh Edition and the Concise Guide to APA Style, Seventh Edition . Any updates to APA Style are noted on the applicable topic pages. If you are still using the sixth edition, helpful resources are available in the sixth edition archive .

NATIONAL PORTRAIT GALLERY

National Portrait Gallery Announces Winner of the 2024 Director’s Essay Prize for Scholars in the Field of Portraiture

Laura Katzman Receives $3,000 and Will Present Lecture Oct. 15

Gabrielle Obusek

The Smithsonian’s National Portrait Gallery has announced Laura Katzman, professor of art history at James Madison University, as the winner of its 2024 Director’s Essay Prize. Her essay, “Lorenzo Homar’s Cine Alba : An Intimate Portrait of North American Artists in Nineteen-Fifties Puerto Rico,” was chosen for its interdisciplinary contributions to the fields of American art, biography, history and cultural identity. The text was published in the book  La mirada en construcción: Ensayos sobre cultura visual (2022), which was edited by José Orlando Sued and René Rodríguez-Ramírez.

Founded in 2019, the Director’s Essay Prize fosters leading research in the field of visual biography and American portraiture. The 2024 prize was juried by PORTAL, the Portrait Gallery’s scholarly center. Its advisors include Martha S. Jones, the Society of Black Alumni Presidential Professor, professor of history and a professor at the SNF Agora Institute at Johns Hopkins University, and Julio Capó, associate professor of history at Florida International University.

“In mining numerous public and private archives, Katzman unveils new understandings and an astute analysis of the work, the artist and his subjects and their lives. In so doing, she offers a nuanced reading of the work and demonstrates how it reflects key social, political and cultural moments in Puerto Rican history and, especially, its place in cultural nationalism. Katzman’s engaging, beautifully written essay is a masterwork in interdisciplinary research and analysis, and the text will serve as an excellent model for future works on portraiture.”

Katzman was the Terra Foundation Visiting Professor at the Freie Universität Berlin from 2018 to 2019 and served as a postdoctoral fellow at the Smithsonian American Art Museum’s Research and Scholars Center. An internationally recognized scholar of 20th-century documentary photography on the U.S. continent and in Puerto Rico, she curated the widely acclaimed retrospective “Ben Shahn, On Nonconformity” for the Museo Nacional Centro de Arte Reina Sofía in Madrid (2023–2024). She is the editor of The Museum of the Old Colony: An Art Installation by Pablo Delano , principal author of Re-viewing Documentary: The Photographic Life of Louise Rosskam, and co-author of the award-winning Ben Shahn’s New York: The Photography of Modern Times . Katzman’s current research examines a post-World War II photographic archive that U.S. artists created for the Puerto Rican government at a time of profound industrial transformation in the Caribbean nation and in the context of its complex colonial relations with the United States.

“The Director’s Essay Prize offers the exciting opportunity to bring wider attention to the extraordinary work of Lorenzo Homar and his collaborations with North American artists at a critical period in Cold War history—a fateful moment for Puerto Rico’s ambiguous political status, distinct cultural identities and long-standing struggles for self-determination.”

Katzman will deliver a lecture on her prize-winning essay , “Lorenzo Homar’s Cine Alba: An Intimate Portrait of North American Artists in Nineteen-Fifties Puerto Rico” Tuesday, Oct. 15, at 5:30 p.m. in the Nan Tucker McEvoy Auditorium at the National Portrait Gallery, Eighth and G Streets N.W., Washington, D.C.

The Director’s Essay Prize complements the Portrait Gallery’s Outwin Boochever Portrait Competition , a triennial juried contemporary art exhibition established in 2006. The prize is specifically dedicated to supporting the next wave of written scholarship on portraiture.
