The basics of apa.

We’re going to start from the beginning for all of you newbies out there, or for those of you looking for a refresher.

APA is an abbreviation which stands for American Psychological Association. This is a massive organization, responsible for creating and sharing psychology-related publications, research, and databases.

Basically, they keep psychologists and other similar roles in the loop with what’s happening in the world of psychology. With close to 120,000 members, this is THE leading world organization related to psychology.They are not officially associated with this guide, but the information here talks about their citing format and rules in depth.

Why were APA citations created and why did my teacher ask me to use this style?

Are you scratching your head, wondering what is APA style is and how this all relates to your research project? To make a long story short, the American Psychological Association did something really cool. Back in 1952, they created a way for ALL psychology researchers to structure their citations. This standard method did three things:

• Psychology researchers were all able to display the sources they used in a systematic way.
• Readers were able to easily understand the information shown in citations.
• There was enough information displayed in the citations for readers to go out and find the exact sources on their own.

APA citations were such a hit, they were so good, that other science disciplines soon adopted the citation format as well. In fact, other disciplines outside of the science world use APA style today, too. So, whether you’re creating a psychology-related research project or not, there’s a good chance you were asked to create your citations in APA style.

Currently in its 7th edition, the Publication Manual of the American Psychological Association is one of the most frequently used style guides for academic writing today!

With the 7th edition just coming onto the scene in 2020, the American Psychological Association does not expect to see widespread usage of the 7th edition until later in 2020. This is why you should always double-check with your teacher on whether they want you to use the 6th edition or the 7th edition for your projects.

Click here for more basics on this style.

Another widely used style is MLA format . Believe it or not, there are thousands of other styles, so perhaps your teacher or professor requested a completely different one. If you’re in that boat, head to EasyBib.com to check out more styles . While you’re at it, poke around and check out our APA reference generator. It may be just what you’re looking for.

References vs. Citations – What’s the difference?

References and citations are two terms that are thrown around a lot and quite often mean the same thing. A reference, or citation, shows the reader that a piece of information originated elsewhere. But, along came APA and decided to throw a curveball at us. In APA, the two terms have two different meanings.

A citation is found in the actual writing of an APA research paper.

In-text citation example:

“Lecture-rooms are numerous and large, but the number of young people who genuinely thirst after truth and justice is small” (Einstein, 2007, p. 5).

A reference is found on the reference page, which is the last page of a research paper. 

Reference Page Example:

Einstein, A. (2007). The world as I see it. Google Books. https://books.google.com/books?id=aNKOo94tO6cC&source=gbs_navlinks_s (Original work published 1934)

The information included in an APA citation is just a snapshot of the information found in the full reference. For more information on when it’s appropriate to include a citation in your paper, head to section 8.1-8.10 of the Publication manual.

Now, what makes things even trickier is that most teachers and professors use the term “APA citations” when they’re actually talking about the full references. How many times have you heard your teacher say, “Make sure you have your citations on the last page!”

Eek! So, to stay on the same page as your teacher, this guide shows you how to make references for an APA reference page, but we’re calling the page “APA Citations.” Someone’s gotta give in, right? Looks like it’s us.

If you’re looking for a quick read on the citations found in the body of the paper, check out our APA Parenthetical Citation page. It’s just one of the many free APA citation guides available on EasyBib.com. Need an APA citation generator? You can find one at EasyBib.com as well!

A rundown on references

Before we get into the nitty-gritty details on how to structure references for your APA paper, let’s get one more quick piece of information off the table.

References are added to research papers and projects only when a source is included in the writing itself.

We don’t add references to a reference page if we want to simply suggest other, similar titles. No! We create references when an actual piece of information from another source is added into the project.

Does your paper include a piece of data from a report? Great! You copied a line of text from a case study and put it in your project (with quotation marks around it)? Perfect! You included a bar graph you found in a brochure? Fantastic! Make sure you create an APA citation in the text of your paper and include the reference on the final page.

The only exception to the above rule is if you’re creating an “annotated bibliography.” For more on that, check out our APA annotated bibliography page.

In case you were wondering, the same goes for MLA in-text & parenthetical citations on the MLA works cited page.

Ready to get started? The next section of the guide is going to explain, step-by-step, how to structure every nook and cranny of your references.

But, if you’re dreaming of an APA citation maker to help make the pain go away from building your references from scratch, you’re in luck. EasyBib.com has an APA citation maker! In just a few clicks, our technology structures and styles each and every APA citation for you. If you don’t know much about it, head to the EasyBib homepage to learn more.

Fundamentals of an APA citation

This entire section goes into detail on each component of a reference. If you’re looking to learn how to style the names of the authors, the title, publishing information, and other aspects related to the reference, this section is for you!

If you want to skip the small talk and see an APA style paper example, go to the “Citation Resources” menu on this page and select “APA Format Guide.” It includes a title page example, an APA paper example, and an APA reference page example.It’s all there for you and the best part about it is it’s free! Do yourself a favor and take a peek at it now!

Author information

The very first piece of information in most references is the author’s name(s). We say “most,” because some sources may not have an author (such as websites, the Bible…). If your source doesn’t have an author, do not include any information about an author in your reference.

Citing a Source with 1 Author

Apa structure:.

Last name of the Author, First initial. Middle initial.

APA Example:

To see some examples, scroll down to the bottom half of this page.

Citing a Source with 2 Authors

Does your source have two authors? Do not put the names in alphabetical order. They should be written in the order they’re displayed on the source.

Last name of the 1st listed Author, First Initial. Middle Initial., & Last name of the 2nd listed Author, First initial. Middle initial.

Doe, J. B. & Chen, W. I.

For an example of a reference with two authors according to the 7th edition of the Publication manual , scroll down to the “Journal Articles found in Print” section, or check out section 9.7-9.12 in the Publication manual.

Citing a Source with 3 to 20 Authors

Does your source have three to twenty authors? The American Psychological Association has made some updates on how to list multiple authors in your citations. If you have between three to twenty authors, list all the authors names (Last Name, Initials). Put them in the same order they’re listed in the source. Commas separate names, and put an ampersand right before the last name.

Bos, G., Hajek, S., Kogman-Appel, K., & Mensching, G. (2019). A Glossary of Latin and Italo-Romance Medico-Botanical Terms in Hebrew Characters on an Illustrated Manuscript Page (Ms. Oxford, Bodleian Opp. 688, fol. 177b). Aleph: Historical Studies in Science and Judaism 19 (2), 169-199. https://www.muse.jhu.edu/article/747571

Citing a Source with 21+ Authors

If your source has over twenty authors, list the last name and initials of the first 19 authors, placing a comma between each name. After the name of the 19th author, use an ellipsis in place of the remaining authors’ names. Then, list the final author’s name in front of it.

Here’s a formatting example for 21+ names using the U.S. presidents (this is NOT a reference example):

Washington, G., Adams, J., Jefferson, T., Madison, J., Monroe, J., Adams, J. Q., Jackson, A., Van Buren, M., Harrison, W. H., Tyler, J., Polk, J., Taylor, Z., Fillmore, M., Pierce, F., Buchanan, J., Lincoln, A., Johnson, A., Grant, U. S., Hayes, R. B., … Trump, D. J.

Citing an Author that is an organization or company

If your source is written by an organization or company:

Some sources are written and released by companies, not necessarily individual people. For example, most brochures at museums only display the institution’s name. Advertisements also only show the company’s name. If the source you’re attempting to cite only shows a group or organization’s name, place it in the reference in the place you’d normally include an individual person’s name.

Write out the name of the group in full; do not use abbreviations. For example, it may seem okay to use USDA, but APA writing style prefers you write out United States Department of Agriculture.

If you’re looking for information on how to style your own name in APA headings, find the example paper on EasyBib.com.

Formatting Titles & Dates

Formatting the date of publication.

The date the source was published is the next item shown in a reference. It’s directly after the author’s name.

For the majority of sources, include only the year in parentheses.

If you’re citing an article in a magazine, include the year and the month.

Peterzell, J. (1990, April). Better late than never. Time, 135 (17), 20–21.

Check out the examples towards the bottom of the page, or head to sections 9.13-9.17 of the Publication manual to see how dates are displayed.

Title rules and capitalization

Titles are the next piece of information shown in a reference. Titles are often tricky for people to style. Students often wonder, “Should I type out the title as it’s shown on the source?” “Should the title be written in italics or underlined?” Here are the answers to (hopefully) all of your title-related questions:

Which letters are capitalized?

Most titles are written with a capital letter in these places:

• At the beginning of the title
• At the beginning of a proper noun
• At the beginning of the subtitle

It may be tempting to write the title as you see it shown on the source, or with capital letters at the beginning of every important word, but that’s not how APA referencing does it.

Here are a few examples of proper lettering:

• A star is born
• Spider-Man: Into the spiderverse
• Harry Potter and the deathly hallows

The only source types that are written with a capital letter at the beginning of every important word are periodicals. Some examples include the titles of newspapers, journals, and magazines.

• The New York Times
• School Library Journal,

How should I style the title?

• Anything that stands alone is written in italics. When we say “stands alone,” we mean it isn’t part of a larger collection. Most books are a single source, so they’re written in italics. Other examples include movies, brochures, dissertations, and music albums.
• Sources that are part of a collection are written without italics. Website pages, journal articles, chapters in books, and individual songs (from an album) are written without italics.
• Remember, the styling information above is for the APA reference page only! Citations in the text of the paper are styled differently. If you need to see a full APA sample paper, check out the other resources on EasyBib.com!

Check out some of the examples below to see how the titles are typed out and styled. You can also head to section 9.18-9.22 of the Publication Manual for more details

If it’s not the actual title, but an APA title page for your paper that you need help with, check out the Title Page APA creator on the homepage of EasyBib.com! Or, check out the main guide for this style, which includes an APA cover page template.

Additional information about a source

It can be difficult to understand a source type just by looking at an APA style citation. Sometimes it isn’t clear if you’re looking at a citation for a presentation, a blog post, lecture notes, or a completely different source type.

To clear up any confusion for your reader, you can include additional information directly after the title. This additional information about the source type is written in brackets with the first word having a capital letter.

Wilson, T. V. & Frey, H. (2019, May 13). Godzilla: The start of his story [Audio podcast]. iHeart Radio. https://www.missedinhistory.com/podcasts/godzilla-the-start-of-his-story.htm

Thanks to the information in the brackets, the reader can easily see that the source is an audio podcast.

Check out the various examples towards the bottom of this page.

Publication information

Publication information includes the name of the publisher. In most cases, the publication information is only included for print sources. Check out the book reference below to see the publication information in action.

Citing a chapter in an edited book in print in APA

An edited book is one that was compiled by an author. Each individual chapter, or section, is written by someone else. Since you’re probably citing the specific chapter, rather than the whole entire book, place the name of the chapter’s author in the first position.

Citing The Bible in APA

Since the bible is considered a “classical work,” and widely known, it is not necessary to create a full reference. Only include a citation in the text of the paper.

Two items need to be included:

• The title and version of the source, such as the New Living Bible
• The names, verses, chapters, or any numbers associated with the section you’re referring to.

“Then the king asked her, “What do you want, Esther? What is your request? I will give it to you, even if it’s half the kingdom” (Esther 5:5 New Living Translation).

Citing a Source on the Internet in APA

Citing digital sources in this style is much easier than other styles. If you’re wondering why, it’s because a lot of information isn’t included in the reference.

For most digital sources, only five items are usually needed:

• The name of the author
• The date the source was published
• The title of the source
• The medium (blog post, audio file, pdf, etc.)
• The website address

Here’s some more information related to web content:

• Only include the medium if it’s unique or if it will help the reader understand the source type.
• Include the website address at the end of the citation.
• Do not place a period at the end of the website address.

Have a digital source? Need to cite APA? Check out some of the examples below.

Citing online encyclopedias & dictionaries – Group author

If you conducted or watched a personal interview and the transcript or audio is not available for the reader, then there really isn’t any point to create a full reference. These types of sources are not recoverable and the reader would be unable to find the interview on their own. Instead, only create a citation in the text of the paper. Use the first initial, middle initial, and last name of the person being interviewed, along with “personal communication,” and the date of the interview.

Institution or organization name. (n.d.). Entry title. In Title of Website or reference . Retrieved Month Day, Year, from URL

Merriam-Webster. (n.d.). Doleful. In Merriam-Webster.com dictionary. Retrieved March 1, 2020, from https://www.merriam-webster.com/dictionary/doleful

Citing online encyclopedias & dictionaries – Known author

If there is a known author, cite the source this way:

Last name, F. M. (Date published). Entry title. In F. M. Last name (ed.), In Title of Website or reference . Retrieved Month Day, Year, from URL

Mann, M. E. & Selin, H. (n.d.). Global warming. In Encyclopaedia Britannica . Retrieved March 1, 2020, from https://www.britannica.com/science/global-warming

Citing Wikipedia

Citing Media Sources in APA

Citing a song or music listened to online in apa.

Note: include a URL in the reference if that location is the only means of retrieval (like if they only post their music to SoundCloud or on their own specific website). If the song is available across multiple platforms, no URL is needed.

APA Structure for a modern song:

Artist’s Last Name, F. M. (Year published). Song’s title [Song].  On Title of album . Publisher(s).

Grande, A. (2019). 7 rings [Song]. On thank u, next . Republic Records.

Solution #3: How to ensure that an auto-generated citation in APA style is correct

• Ensure that the correct number of people are accredited by counting the names in the source and the website citation.
• Ensure that all names are spelled correctly.
• If 2-20 authors are used, ensure that an ampersand is used before the last name.
• If more than twenty authors are used, ensure that an ellipsis is used before the final author.
• Check to make sure that the date is correct and that the month or year do not need to be adjusted.
• Generally, works cited as a whole, such as books, are written in italics, while shorter works that are part of a bigger work, such as a chapter in a book or articles from a periodical (e.g., journal, magazine, newspaper, etc.), are usually in regular font.
• The title of webpages are italicized, while the title of the site they are on is in regular font.
• Social media post citations use the written post content (up to 20 words) as the title. This “title” should be italicized.
• If using a chapter, make sure that the editor is accredited.
• If using an article, make sure that the journal number is italicized and that the volume number is in parentheses.
• Make sure that your links are active and that they bring you to the correct location. You may need to rewrite the link.

Appropriate Level of Citation

The number of sources you cite in your paper depends on the purpose of your work. For most papers, cite one or two of the most representative sources for each key point. Literature review papers, however, typically include a more exhaustive list of references.

Provide appropriate credit to the source (e.g., by using an in-text citation) whenever you do the following:

• paraphrase (i.e., state in your own words) the ideas of others
• directly quote the words of others
• refer to data or data sets
• reprint or adapt a table or figure, even images from the internet that are free or licensed in the Creative Commons
• reprint a long text passage or commercially copyrighted test item

Avoid both undercitation and overcitation. Undercitation can lead to plagiarism and/or self-plagiarism . Overcitation can be distracting and is unnecessary.

For example, it is considered overcitation to repeat the same citation in every sentence when the source and topic have not changed. Instead, when paraphrasing a key point in more than one sentence within a paragraph, cite the source in the first sentence in which it is relevant and do not repeat the citation in subsequent sentences as long as the source remains clear and unchanged.

Figure 8.1 in Chapter 8 of the Publication Manual provides an example of an appropriate level of citation.

Determining the appropriate level of citation is covered in the seventh edition APA Style manuals in the Publication Manual Section 8.1 and the Concise Guide Section 8.1

A Quick Guide to Referencing | Cite Your Sources Correctly

Referencing means acknowledging the sources you have used in your writing. Including references helps you support your claims and ensures that you avoid plagiarism .

There are many referencing styles, but they usually consist of two things:

• A citation wherever you refer to a source in your text.
• A reference list or bibliography at the end listing full details of all your sources.

The most common method of referencing in UK universities is Harvard style , which uses author-date citations in the text. Our free Harvard Reference Generator automatically creates accurate references in this style.

Referencing styles, citing your sources with in-text citations, creating your reference list or bibliography, harvard referencing examples, frequently asked questions about referencing.

Each referencing style has different rules for presenting source information. For in-text citations, some use footnotes or endnotes , while others include the author’s surname and date of publication in brackets in the text.

The reference list or bibliography is presented differently in each style, with different rules for things like capitalisation, italics, and quotation marks in references.

Your university will usually tell you which referencing style to use; they may even have their own unique style. Always follow your university’s guidelines, and ask your tutor if you are unsure. The most common styles are summarised below.

Harvard referencing, the most commonly used style at UK universities, uses author–date in-text citations corresponding to an alphabetical bibliography or reference list at the end.

Harvard Referencing Guide

Vancouver referencing, used in biomedicine and other sciences, uses reference numbers in the text corresponding to a numbered reference list at the end.

In-text citations should be used whenever you quote, paraphrase, or refer to information from a source (e.g. a book, article, image, website, or video).

Quoting and paraphrasing

Quoting is when you directly copy some text from a source and enclose it in quotation marks to indicate that it is not your own writing.

Paraphrasing is when you rephrase the original source into your own words. In this case, you don’t use quotation marks, but you still need to include a citation.

In most referencing styles, page numbers are included when you’re quoting or paraphrasing a particular passage. If you are referring to the text as a whole, no page number is needed.

In-text citations

In-text citations are quick references to your sources. In Harvard referencing, you use the author’s surname and the date of publication in brackets.

Up to three authors are included in a Harvard in-text citation. If the source has more than three authors, include the first author followed by ‘ et al. ‘

The point of these citations is to direct your reader to the alphabetised reference list, where you give full information about each source. For example, to find the source cited above, the reader would look under ‘J’ in your reference list to find the title and publication details of the source.

Placement of in-text citations

In-text citations should be placed directly after the quotation or information they refer to, usually before a comma or full stop. If a sentence is supported by multiple sources, you can combine them in one set of brackets, separated by a semicolon.

If you mention the author’s name in the text already, you don’t include it in the citation, and you can place the citation immediately after the name.

• Another researcher warns that the results of this method are ‘inconsistent’ (Singh, 2018, p. 13) .
• Previous research has frequently illustrated the pitfalls of this method (Singh, 2018; Jones, 2016) .
• Singh (2018, p. 13) warns that the results of this method are ‘inconsistent’.

The terms ‘bibliography’ and ‘reference list’ are sometimes used interchangeably. Both refer to a list that contains full information on all the sources cited in your text. Sometimes ‘bibliography’ is used to mean a more extensive list, also containing sources that you consulted but did not cite in the text.

A reference list or bibliography is usually mandatory, since in-text citations typically don’t provide full source information. For styles that already include full source information in footnotes (e.g. OSCOLA and Chicago Style ), the bibliography is optional, although your university may still require you to include one.

Format of the reference list

Reference lists are usually alphabetised by authors’ last names. Each entry in the list appears on a new line, and a hanging indent is applied if an entry extends onto multiple lines.

Different source information is included for different source types. Each style provides detailed guidelines for exactly what information should be included and how it should be presented.

Below are some examples of reference list entries for common source types in Harvard style.

• Chapter of a book
• Journal article

Your university should tell you which referencing style to follow. If you’re unsure, check with a supervisor. Commonly used styles include:

• Harvard referencing , the most commonly used style in UK universities.
• MHRA , used in humanities subjects.
• APA , used in the social sciences.
• Vancouver , used in biomedicine.
• OSCOLA , used in law.

Your university may have its own referencing style guide.

If you are allowed to choose which style to follow, we recommend Harvard referencing, as it is a straightforward and widely used style.

References should be included in your text whenever you use words, ideas, or information from a source. A source can be anything from a book or journal article to a website or YouTube video.

If you don’t acknowledge your sources, you can get in trouble for plagiarism .

To avoid plagiarism , always include a reference when you use words, ideas or information from a source. This shows that you are not trying to pass the work of others off as your own.

You must also properly quote or paraphrase the source. If you’re not sure whether you’ve done this correctly, you can use the Scribbr Plagiarism Checker to find and correct any mistakes.

Harvard referencing uses an author–date system. Sources are cited by the author’s last name and the publication year in brackets. Each Harvard in-text citation corresponds to an entry in the alphabetised reference list at the end of the paper.

Vancouver referencing uses a numerical system. Sources are cited by a number in parentheses or superscript. Each number corresponds to a full reference at the end of the paper.

APA In-Text Citations and Sample Essay 7th Edition

This handout focuses on how to format in-text citations in APA.

Proper citation of sources is a two-part process . You must first cite each source in the body of your essay; these citations within the essay are called in-text citations . You MUST cite all quoted, paraphrased, or summarized words, ideas, and facts from sources. Without in-text citations, you are technically in danger of plagiarism, even if you have listed your sources at the end of the essay.

In-text citations point the reader to the sources’ information on the references page. The in-text citation typically includes the author's last name and the year of publication. If you use a direct quote, the page number is also provided.

More information can be found on p. 253 of the 7th edition of the Publication Manual of the American Psychological Association.

Citation Rules

Direct quotation with the author named in the text.

Heinze and Lu (2017) stated, “The NFL shifted its responses to institutional change around concussions significantly as the field itself evolved” (p. 509).

Note: The year of publication is listed in parenthesis after the names of the authors, and the page number is listed in parenthesis at the end of the quote.

Direct Quotation without the Author Named in the Text

As the NFL developed as an organization, it “shifted its responses to institutional change around concussions significantly” (Heinze & Lu, 2017, p. 509).

Note: At the end of the quote, the names of the authors, year of publication, and page number are listed in parenthesis.

Paraphrase with 1-2 Authors

As the NFL developed as an organization, its reactions toward concussions also transformed (Heinze & Lu, 2017).

Note: For paraphrases, page numbers are encouraged but not required.

Paraphrase with 3 or More Authors

To work toward solving the issue of violence in prisons begins with determining aspects that might connect with prisoners' violent conduct (Thomson et al., 2019).

Direct Quotation without an Author

The findings were astonishing "in a recent study of parent and adult child relationships" ("Parents and Their Children," 2007, p. 2).

Note: Since the author of the text is not stated, a shortened version of the title is used instead.

Secondary Sources

When using secondary sources, use the phrase "as cited in" and cite the secondary source on the References page.

In 1936, Keynes said, “governments should run deficits when the economy is slow to avoid unemployment” (as cited in Richardson, 2008, p. 257).

Long (Block) Quotations

When using direct quotations of 40 or more words, indent five spaces from the left margin without using quotation marks. The final period should come before the parenthetical citation.

At Meramec, an English department policy states:

To honor and protect their own work and that of others, all students must give credit to proprietary sources that are used for course work. It is assumed that any information that is not documented is either common knowledge in that field or the original work of that student. (St. Louis Community College, 2001, p. 1)

Website Citations

If citing a specific web document without a page number, include the name of the author, date, title of the section, and paragraph number in parentheses:

In America, “Two out of five deaths among U.S. teens are the result of a motor vehicle crash” (National Center for Injury Prevention and Control, 2004, Overview section, para. 1).

Here is a print-friendly version of this content.

MLA Works Cited: Electronic Sources (Web Publications)

Welcome to the Purdue OWL

This page is brought to you by the OWL at Purdue University. When printing this page, you must include the entire legal notice.

Copyright ©1995-2018 by The Writing Lab & The OWL at Purdue and Purdue University. All rights reserved. This material may not be published, reproduced, broadcast, rewritten, or redistributed without permission. Use of this site constitutes acceptance of our terms and conditions of fair use.

The MLA Handbook highlights principles over prescriptive practices. Essentially, a writer will need to take note of primary elements in every source, such as author, title, etc. and then assort them in a general format. Thus, by using this methodology, a writer will be able to cite any source regardless of whether it’s included in this list.

However, this guide will highlight a few concerns when citing digital sources in MLA style.

Best Practices for Managing Online Sources

Because online information can change or disappear, it is always a good idea to keep personal copies of important electronic information whenever possible. Downloading or even printing key documents ensures you have a stable backup. You can also use the Bookmark function in your web browser in order to build an easy-to-access reference for all of your project's sources (though this will not help you if the information is changed or deleted).

It is also wise to keep a record of when you first consult with each online source. MLA uses the phrase, “Accessed” to denote which date you accessed the web page when available or necessary. It is not required to do so, but it is encouraged (especially when there is no copyright date listed on a website).

Important Note on the Use of URLs in MLA

Include a URL or web address to help readers locate your sources. Because web addresses are not static (i.e., they change often) and because documents sometimes appear in multiple places on the web (e.g., on multiple databases), MLA encourages the use of citing containers such as Youtube, JSTOR, Spotify, or Netflix in order to easily access and verify sources. However, MLA only requires the www. address, so eliminate all https:// when citing URLs.

Many scholarly journal articles found in databases include a DOI (digital object identifier). If a DOI is available, cite the DOI number instead of the URL.

Online newspapers and magazines sometimes include a “permalink,” which is a shortened, stable version of a URL. Look for a “share” or “cite this” button to see if a source includes a permalink. If you can find a permalink, use that instead of a URL.

Abbreviations Commonly Used with Electronic Sources

If page numbers are not available, use par. or pars. to denote paragraph numbers. Use these in place of the p. or pp. abbreviation. Par. would be used for a single paragraph, while pars. would be used for a span of two or more paragraphs.

Basic Style for Citations of Electronic Sources (Including Online Databases)

Here are some common features you should try to find before citing electronic sources in MLA style. Not every web page will provide all of the following information. However, collect as much of the following information as possible:

• Author and/or editor names (if available); last names first.
• "Article name in quotation marks."
• Title of the website, project, or book in italics.
• Any version numbers available, including editions (ed.), revisions, posting dates, volumes (vol.), or issue numbers (no.).
• Publisher information, including the publisher name and publishing date.
• Take note of any page numbers (p. or pp.) or paragraph numbers (par. or pars.).
• DOI (if available, precede it with "https://doi.org/"), otherwise a URL (without the https://) or permalink.
• Date you accessed the material (Date Accessed). While not required, saving this information it is highly recommended, especially when dealing with pages that change frequently or do not have a visible copyright date.

Use the following format:

Author. "Title." Title of container (self contained if book) , Other contributors (translators or editors), Version (edition), Number (vol. and/or no.), Publisher, Publication Date, Location (pages, paragraphs and/or URL, DOI or permalink). 2 nd container’s title , Other contributors, Version, Number, Publisher, Publication date, Location, Date of Access (if applicable).

Citing an Entire Web Site

When citing an entire website, follow the same format as listed above, but include a compiler name if no single author is available.

Author, or compiler name (if available). Name of Site. Version number (if available), Name of institution/organization affiliated with the site (sponsor or publisher), date of resource creation (if available), DOI (preferred), otherwise include a URL or permalink. Date of access (if applicable).

Editor, author, or compiler name (if available). Name of Site . Version number, Name of institution/organization affiliated with the site (sponsor or publisher), date of resource creation (if available), URL, DOI or permalink. Date of access (if applicable).

A Page on a Web Site

For an individual page on a Web site, list the author or alias if known, followed by an indication of the specific page or article being referenced. Usually, the title of the page or article appears in a header at the top of the page. Follow this with the information covered above for entire Web sites. If the publisher is the same as the website name, only list it once.

“ Athlete's Foot - Topic Overview. ”   WebMD , 25 Sept. 2014, www.webmd.com/skin-problems-and-treatments/tc/athletes-foot-topic-overview.

Citations for e-books closely resemble those for physical books. Simply indicate that the book in question is an e-book by putting the term "e-book" in the "version" slot of the MLA template (i.e., after the author, the title of the source, the title of the container, and the names of any other contributors).

Silva, Paul J.  How to Write a Lot: A Practical Guide to Productive Academic Writing. E-book, American Psychological Association, 2007.

If the e-book is formatted for a specific reader device or service, you can indicate this by treating this information the same way you would treat a physical book's edition number. Often, this will mean replacing "e-book" with "[App/Service] ed."

Machiavelli, Niccolo.  The Prince , translated by W. K. Marriott, Kindle ed., Library of Alexandria, 2018.

Note:  The MLA considers the term "e-book" to refer to publications formatted specifically for reading with an e-book reader device (e.g., a Kindle) or a corresponding web application. These e-books will not have URLs or DOIs. If you are citing book content from an ordinary webpage with a URL, use the "A Page on a Web Site" format above.

An Image (Including a Painting, Sculpture, or Photograph)

Provide the artist's name, the work of art italicized, the date of creation, the institution and city where the work is housed. Follow this initial entry with the name of the Website in italics, and the date of access.

An Article in an Online Scholarly Journal

For all online scholarly journals, provide the author(s) name(s), the name of the article in quotation marks, the title of the publication in italics, all volume and issue numbers, and the year of publication. Include a DOI if available, otherwise provide a URL or permalink to help readers locate the source.

Article in an Online-only Scholarly Journal

MLA requires a page range for articles that appear in Scholarly Journals. If the journal you are citing appears exclusively in an online format (i.e. there is no corresponding print publication) that does not make use of page numbers, indicate the URL or other location information.

Dolby, Nadine. “Research in Youth Culture and Policy: Current Conditions and Future Directions.” Social Work and Society: The International Online-Only Journal, vol. 6, no. 2, 2008, www.socwork.net/sws/article/view/60/362. Accessed 20 May 2009.

How to Cite Sources

Last Updated: July 9, 2024 Fact Checked

This article was co-authored by Diane Stubbs and by wikiHow staff writer, Jennifer Mueller, JD . Diane Stubbs is a Secondary English Teacher with over 22 years of experience teaching all high school grade levels and AP courses. She specializes in secondary education, classroom management, and educational technology. Diane earned a Bachelor of Arts in English from the University of Delaware and a Master of Education from Wesley College. There are 12 references cited in this article, which can be found at the bottom of the page. This article has been fact-checked, ensuring the accuracy of any cited facts and confirming the authority of its sources. This article has been viewed 1,664,701 times.

When you paraphrase or quote information from another source in a research paper, essay, or other written work, cite the original source of the information. Otherwise, your readers believe you are trying to pass this information off as your original thought. Proper citation adds credibility to your work and provides evidence to support any arguments you make. Your citations also give your readers the opportunity to further explore the topic of your work on their own. [1] X Research source

Citation Help

Gathering Information about Your Sources

• Generally, you'll have full citations listed at the end of your paper. The citation list may be called a reference list, bibliography, or Works Cited, depending on the type of citation style you're using.
• Within the body of your paper, use in-text citations to signal that the material preceding the citation is not your original work. The in-text citation allows your reader to find the full citation at the end of your paper. In-text citations may use the in-line parenthetical, footnote, or endnote style.

Tip: Save time and reduce the risk of error by making a photo or screenshot of the title page or top of the article that clearly shows the author and title.

• For a print source, find the publication information on the back of the title page. Look for the copyright information. In print magazines and journals, this information typically appears on the same page as the table of contents, or on the page that lists the periodical's staff.
• For articles online, use the date that appears on the article itself – not the copyright date for the website. To identify the publisher of the website, look for an "about" page. You may also be able to find this information at the bottom of the homepage.
• If you're citing an article that appears in a magazine or journal, write down the pages on which the article appears.

• If you accessed a scholarly article from an online database , it may have a digital object identifier (DOI). Use this number instead of a URL.

Tip: Double-check your online sources the day before you turn your paper in. That way if anything has moved or changed, you can make sure you have the most up-to-date information. Use that date as your date of access in your citations.

Placing In-Text Citations

Note: For some citation styles that use footnotes or endnotes, the superscript number appears immediately after the paraphrased or quoted material, rather than at the end of the sentence. Consult the guide for the citation style you're using to make sure.

• If you include the author's name in your text, put the year in parentheses immediately after their name. For example: Allison (1987) demonstrated that leaving the ground in sod increases the organic matter of the soil by 15 percent in 10 years.
• If you're quoting the source directly, include the page number in your in-text parenthetical citation. For example: Allison (1987) asserted that "leaving the ground in sod increases the organic matter of the soil by 15 percent in 10 years" (p. 45).

Example: Leaving the ground in sod increases the organic matter of the soil by 15 percent in 10 years (Allison, 1987).

• Generally, you'll separate the elements of the citation with commas rather than periods. Publication information typically is set off in parentheses. The only period in a Chicago-style footnote occurs at the very end. For example: Kent Portney, Taking Sustainable Cities Seriously (Cambridge: MIT Press, 2003).

Example: Leaving the ground in sod increases the organic matter of the soil by 15 percent in 10 years. 1

• If the source you're citing doesn't have an author, use a shortened version of the title instead. Use enough of the title that your reader could easily find the full reference entry in your Works Cited. Put the title in quotation marks. For example, if you were creating a parenthetical citation for a source called "Taking Sustainable Cities Seriously," and it didn't have an author, you might use: ("Sustainable Cities" 57).

Example: Leaving the ground in sod increases the organic matter of the soil by 15 percent in 10 years (Alison 45).

Writing a Reference Entry

• The most common format for author's names is to place the last name first, followed by a comma, then the first name. Typically you will close this portion of the reference entry with a period. For example: Hawking, Stephen.
• For some citation styles, such as APA style, only include the author's first initial in your reference entry, rather than their full first name. For example: Hawking, S. W.
• If you're citing a work with three or more authors in MLA or APA, or one with more than 10 authors in Chicago style, you'll need to cite with cite with "et al." instead of listing all authors.

• For example: Hawking, S. W. (1998).
• For some sources, such as magazines and newspapers, you need a more specific date. Type the year first, followed by a comma. Then type the month and day the article was published. For example: Hawking, S. W. (2005, July).

• Journal article example: Hawking, Stephen. "Information Loss in Black Holes." Physical Review , July 2005.
• Most citation styles require titles in title-case, meaning that all nouns, pronouns, verbs, and adverbs are capitalized. For example: Hawking, Stephen. A Brief History of Time .
• APA style uses sentence-case for titles, capitalizing only the first word and any proper pronouns. For example: Hawking, S. W. (1998). A brief history of time.

• APA example: Hawking, S. W. (1998). A brief history of time. New York: Bantam.
• For print sources, most styles call for the city and state where the source was published (or city and country, for sources published outside the U.S.) to be listed first. The location is typically followed by a colon, after which the name of the publisher is listed. For example: Hawking, Stephen. A Brief History of Time . New York: Bantam, 1998.
• For most citation styles, the year the source was published follows the name of the publisher. Typically only the year is needed, although for periodical publications, such as newspapers or magazines, you may need a more specific date.
• The year of publication typically is the copyright year. However, for online sources, look for a date the specific article was published rather than using the copyright year of the website as a whole.

• Many scholarly articles are available through online databases. If you accessed an article through one of these databases, you'll typically provide the article's unique digital object identification (DOI) number, rather than a URL. For some citation styles, you must also include the name of the database in your reference entry.

Example: Clark, Stuart. "A Brief History of Stephen Hawking: A Legacy of Paradox." New Scientist , 21 March 2018. https://www.newscientist.com/article/mg23731700-100-a-brief-history-of-stephen-hawking-a-legacy-of-paradox/. Accessed 2 October 2018.

How to cite a website in APA, MLA, or Harvard style

There are many different ways to cite a website, depending on which citation style you need to format it in.

 The easy way to cite a website in any citation style

Use our citation generator below to automatically cite a website in any style, including APA, MLA 7 and 8, and Harvard. Just select the style you need, copy the URL into the search box, and press search. We’ll do the rest.

 The manual way to cite a website

To cite a website by hand just follow the instructions below. For the 3 most popular styles–APA, MLA 8, and Harvard–this is as follows:

 In APA style

You need to locate these details for the website: page or article author, page or article title, website name, published date, access date, page URL (web address) .

• The author can typically be found on the page, but if there isn’t one listed you can use the website name in its place.
• The page title can be found near the top of the page, and you can also find it by hovering your mouse over the browser tab.
• The website name can usually be found in the web address or by looking for a logo or similar at the very top of the page.
• There often isn’t a publish date , but if there is it’ll be very close to the page title.
• The access date is the date you took information from the article (usually today).
• The page URL can be copied straight from the address bar of your browser and will start with either http:// or https://.

Then use this template, replacing the colored placeholders with the information you found on the page:

Author last name , author first name initial . ( published year , published month and day ). Page title . Retrieved accessed month and day , accessed year , from article URL .

The final formatted citation should look like this:

Ingle, S. (2018, February 11). Winter Olympics was hit by cyber-attack, officials confirm. Retrieved July 24, 2018, from https://www.theguardian.com/sport/2018/feb/11/winter-olympics-was-hit-by-cyber-attack-officials-confirm.

How do I cite quotations from different pages of a work?

When citing quotations from different pages of a work, some writers are tempted to use a page range as a citation. For example:

Don Quixote’s intention to “do battle” with the “thirty or forty hulking giants” in the distance alarms Sancho Panza, who tells Don Quixote that they “are not giants but windmills” and that no one “could have mistaken them unless he had windmills in his brain” (Cervantes 98–99). Work Cited Cervantes, Miguel de.  Don Quixote of La Mancha . Translated by Walter Starkie, Signet Classic, 1964.

But this method is not preferable in MLA style. There are four quotations in this example, and it’s unclear which ones appear on page 98 and which on page 99, or perhaps on both pages. It’s best to tell readers exactly which page each quotation comes from. The following revision shows how to cite the quotations in MLA style:

Don Quixote’s intention to “do battle” with the “thirty or forty hulking giants” in the distance alarms Sancho Panza (Cervantes 98), who tells Don Quixote that they “are not giants but windmills” and that no one “could have mistaken them unless he had windmills in his brain” (98, 99). Work Cited Cervantes, Miguel de.  Don Quixote of La Mancha . Translated by Walter Starkie, Signet Classic, 1964.

In the revised example, the citation before the comma, (Cervantes 98), indicates that the first two quotations appear on page 98. The citation at the end of the sentence, (98, 99), indicates that the third and fourth quotations appear on pages 98 and 99, respectively.

Oceans without sharks would be far less healthy – new research

Executive Dean of the College of Arts, Sciences & Education and Professor of Biological Sciences, Florida International University

Disclosure statement

Michael Heithaus receives funding from the Shark Conservation Fund and the National Science Foundation.

Florida International University provides funding as a member of The Conversation US.

There are more than 500 species of sharks in the world’s oceans, from the 7-inch dwarf lantern shark to whale sharks that can grow to over 35 feet long. They’re found from polar waters to the equator, at the water’s surface and miles deep, in the open ocean, along coasts and even in some coastal rivers .

With such diversity, it’s no surprise that sharks serve many ecological functions. For example, the largest individuals of some big predatory species, such as tiger and white sharks, can have an oversized role in maintaining balances among species. They do this by feeding on prey and sometimes by just being present and scary enough that prey species change their habits and locations.

In a newly published study , colleagues and I surveyed decades of research on sharks’ ecological roles and considered their future in oceans dominated by people. We found that because sharks play such diverse and sometimes important functions in maintaining healthy oceans, their current decline is an urgent problem. Since 1970, global populations of sharks and rays have decreased by more than 70% .

People are killing many types of sharks at unsustainable rates , mainly through overfishing. We see a need for nations to rethink where and how to conserve sharks for healthy oceans.

How sharks foster seagrasses

Along the remote coast of Western Australia, more than two decades of work shows that the mere presence of tiger sharks shapes the entire seagrass ecosystem by changing where and how big grazers, such as sea turtles and sea cows, feed.

Having tiger sharks nearby protects wide swaths of seagrass from being overgrazed, allowing it to grow into thick underwater meadows that provide habitat for juvenile fish and shellfish. These species are important food for other animals and for humans.

In places where tiger sharks have declined and turtle populations have expanded, seagrasses are being overgrazed. In Bermuda, for example, the exploding turtle population has led to an almost total collapse of seagrasses .

White sharks produce some of the same effects. Along the California coast, where white shark numbers are increasing , otters are spending more time in the safety of protected inland waters and less time in the open waters of Monterey Bay. The otters prey on crabs, which in turn feed on grazing invertebrates such as sea slugs that clean algae from seagrasses. More otters means fewer crabs, more grazers and healthier seagrasses .

Kelp forests and reefs

Kelp forests are dense stands of large brown algae that grow in shallow zones near coasts. Along the U.S. West Coast, overhunting drove local populations of sea otters to extinction by the early 1900s . This caused huge kelp forest losses by allowing sea urchins – a favorite food of otters – to spread and consume kelp .

Over the past 50 years, otter populations have rebounded with federal protection . But as white sharks expand their ranges northward, they are preventing otters from expanding their range because there aren’t kelp forests for the otters to hide in.

The otters will likely expand their ranges only once kelp forests become established. This complicates restoration efforts, since otters won’t be removing enough urchins for kelp to become established.

When sharks are present near coral reefs, fish avoid the sharks by sticking close to the safety of the reef. This reduces grazing on seagrasses and algae across wide areas . There is still much to learn, however, about when, where and how sharks might be important for coral reef health.

Food and nutrient sources

Sharks can also be prey. Some, including large species like white sharks , are important food sources for some killer whale populations around the world . Smaller sharks, including blacktip sharks, can be key menu items for larger sharks, such as great hammerheads.

As sharks consume prey in one place and excrete waste elsewhere, they move nutrients throughout the ocean. In the Pacific, for example, gray reef sharks move nitrogen from the offshore waters where they feed to the coral reefs where they spend their days, providing important fertilizer for ocean food webs.

In Florida’s coastal waters , young bull sharks feed during brief visits to the ocean, then return to safer, nearly freshwater rivers, where they spend most of their time and release nutrients in their waste.

Sometimes sharks’ presence helps other fish. In the open ocean, sharks’ rough scales make perfect scratching posts for fish to remove parasites.

Protecting sharks’ roles

Our review makes clear that sharks play diverse roles in maintaining healthy oceans. We see important implications for shark conservation.

Step 1 would be to set goals beyond simply ensuring that there are sharks in the oceans and to target species that have key ecological roles.

Within populations, it is important to protect certain types of individual sharks. For example, the largest tiger sharks are the ones that shape the behavior of turtles and sea cows, benefiting seagrass ecosystems. Intensive fishing worldwide makes it extremely challenging for large sharks that can live for decades or even centuries to survive and grow to ecologically important sizes.

Working with local communities in coastal areas could build support for protecting these large ocean predators, much as conservationists are working on land to protect iconic predators such as wolves . Nations could build networks of large protected areas that forbid shark fishing, focusing on key areas where individual sharks may roam.

Research shows that sharks benefit from creating protected areas, limiting shark catch outside these zones and restricting use of fishing gear that does the most harm to sharks , such as gill nets and longlines . With a clearer understanding of sharks’ ecological value, my colleagues and I hope to see focused action at all levels to protect these essential animals.

The Emotion I Didn’t Expect as a New Parent: Regret

By Miguel Macias

A journalist, audio producer and public radio reporter based in Spain.

This essay is part of How to Live With Regret, a series exploring the nature of regret and the role it plays in all our lives. Read more about this project here .

When friends ask me how I’m feeling 18 months after having a baby, I usually tell them that it has been wonderful. Sometimes, though, if I’m feeling particularly confessional, I will smile coyly and say: “Well, this is not the life I wanted. But the life I had before was not the life I wanted, either.” I say it in a cheeky, half-joking way, hoping the gravity of the comment will go unnoticed. But it’s not a joke.

Since my daughter, Olivia, was born, I have cycled through a huge range of emotions. I expect many of them would be familiar to any parent: joy, exhaustion, deep love, confusion, wonder, exasperation, happiness, sadness. But there is another, quieter, emotion that comes up every now and then. It’s a feeling that’s so difficult to talk about, so universally taboo, that I feel nervous expressing it even to the people closest to me: regret.

Since I was a teenager, I knew that I did not want to have kids. I did not budge for decades, and I had quite the battery of reasons for feeling this way, from the emotional to the practical — the biggest one being that there were simply too many things I wanted to accomplish in life, and a baby would surely get in the way.

When I was young I dreamed of becoming a famous filmmaker, traveling the world making documentaries. It hardly seemed like a good way to raise a kid. But I also just never had any interest in babies or kids. Rather, I felt resolved, ironclad in my conviction that I would never be a father.

But things change. I settled down. And at 47, my life didn’t look like the one I had once envisioned for myself. To be clear, I have a lot to be proud of. I do work that I care about as a radio producer and reporter, and I’ve been fairly successful. But I didn’t set the world on fire. I am not traveling the globe chasing major stories and winning Oscars. And over time the reasons I’d held onto for why I did not want to have children slowly faded.

Brazil central bank will do 'whatever is necessary' to control inflation, director says

Brazil's central bank will do "whatever is necessary" to control inflation, monetary policy director Gabriel Galipolo said on Thursday, adding that risks appeared to be to the upside of its 3% target.
