How to Reference a Person With a PhD

How to sign your name when you have a bachelor of science in criminal ....

As you have probably noticed, many authors of books and articles are learned individuals who have received doctorates. Therefore, you may sometimes find that you need to cite authors who have the suffix "Ph.D." listed after their names. However, if you listed "Ph.D." after the name of every author who had one, your term paper would quickly devolve into alphabet soup. Both American Psychological Association (APA) and Modern Language Association (MLA) styles agree on this point: never include the suffix "Ph.D." after an author's name when you are citing sources.

Omit the suffix "Ph.D." from the author's name when citing sources in your reference list. For example, a book authored by Jordan Jones, Ph.D. would be listed as being authored by Jordan Jones. In MLA style this would appear as: Jones, Jordan. In APA style, this would appear as: Jones, J.

Omit as well any titles such as "Ph.D." from the names of translators, editors, or any other names that might appear in your reference list entries.

Omit titles such as "Ph.D." from your in-text citations as well. Use only the last names of authors, editors and other persons in parenthetical citations. In MLA style, an in-text citation for the work of Jordan Jones, Ph.D. should appear as follows: (Jones 86). In APA, the same citation should appear as follows: (Jones, 2009, p. 86).

How to Cite Doctors in APA

Although you may think explaining that an author of one of your research paper's sources holds a professional degree like Doctor of Medicine, the American Psychological Association, or APA, style does not include indications such as M.D. in either in-text citations or the references list at the end.

Formatting Requirements

In APA style, in-text citations include only the author's last name along with the date. First initials only appear if you have multiple authors with the same last name. Therefore, no professional degree indications appear.

A citation from a doctor would look like this: (Hazu, 2014). You may instead include information within a signal phrase to indicate the source's expertise, such as, "Dr. Hazu, an internist with 30 years' experience at the Mayo Clinic, disagrees."

Likewise, no indication of the doctor's professional degree appears on the references entry. The entry for Dr. Hazu would follow this structure:

Hazu, D. (2014). Pandemics in the 21st century. American Medical Journal, 13 (3), 24-29.

Are titles such as doctor included in author's name on the References page?

Author titles such as MD and PhD are not included on the References page or in-text citations in APA Style.

From the APA Blog:

If mentioning an author’s academic credentials or professional title in the text because it is relevant to the discussion, use the format without periods (for example PhD, not Ph.D.)

• Titles may be used in the body of the paper, according to some Instructors at Baker College.
• If the professor at your college says otherwise, follow their advice.

• The answer given about the use of titles in text has been difficult to find. A professor at a different college told me to never use authors titles such as "PhD" or "Dr." However, this site states otherwise. Is information about the use of titles in text on an APA website so that I can check for verification? Thanks! by Mary-Ann on Apr 17, 2017
• You are correct that titles are not used in APA for in-text citations or on the References page. A faculty person in the English department at Baker College said that titles may be used in the body of the paper if you wish, but if your professor says otherwise, follow his or her advice. by ASK US on Apr 18, 2017
• What about situations in evaluations when you are noting how a patient was seen by a physician? Example: Which is correct: A: "JohnnyBoy is seen regularly by his pediatrician, Jane Doe, MD., who referred him to optometrist, Isee More, OD." B: "JohnnyBoy is seen regularly by his pediatrician, Dr. Jane Doe, who referred him to optometrist, Dr. Isee More." C: "JohnnyBoy is seen regularly by his pediatrician, Jane Doe, who referred him to optometrist, Isee More." by fosgate3 on Sep 03, 2019
• I found this on the APA Blog: Note that if you do want to mention an author’s academic credentials or professional title in the text because it is relevant to the discussion, you should use the format without periods (e.g., PhD, not Ph.D.) So, your answer of A above is correct, except there would not be period after the MD. by ASK US Librarian on Sep 18, 2019

What is APA?

APA style was created by the American Psychological Association. It is a set of rules for publications, including research papers.

In APA, you must "cite" sources that you have paraphrased, quoted or otherwise used to write your research paper. Cite your sources in two places:

• In the body of your paper where you add a brief in-text citation.
• In the Reference list at the end of your paper where you give more complete information for the source.

Two copies of the print edition of APA 7 are available at the Help Desk for onsite use only.

What's New in the Seventh Edition?

Here's a summary of major changes in the 7th edition of the APA Publication Manual.

Essay Format:

• Font  - While you still can use Times New Roman 12, you are free to use other fonts. Calibri 11, Arial 11, Lucida Sans 10, and Georgia 11 are all acceptable.
• Headers  - No running headers are required for student papers.
• Tables and Figures  - There is a standardized format for both tables and figures.

Style, Grammar, Usage:

• Singular "they" required in two situations: when used by a known person as their personal pronoun or when the gender of a singular person is not known.
• Use only one space after a sentence-ending period.

Citation Style:

• New "Four Elements of a Reference" (Author, Date, Title, Source) to help writers create references for source types not explicitly examined in the APA Manual.
• Three or more authors can be abbreviated to First author, et al. on the first citation.
• Up to 20 authors are named in the References List.
• Publisher location is not required for books.
• Ebook platform, format, or device is not required for eBooks.  
• Library database names are generally not required.
• No "doi:" prefix, simply include the doi.
• All hyperlinks retain the https://
• Links can be "live" in blue with underline or black without underlining

How to Cite a Thesis or Dissertation in APA

In this citation guide, you will learn how to reference and cite an undergraduate thesis, master’s thesis, or doctoral dissertation. This guide will also review the differences between a thesis or dissertation that is published and one that has remained unpublished. The guidelines below come from the 7th edition of the Publication Manual of the American Psychological Association (2020a), pages 333 and 334. Please note that the association is not affiliated with this guide.

Alternatively, you can visit EasyBib.com for helpful citation tools to cite your thesis or dissertation .

Guide Overview

Citing an unpublished thesis or dissertation, citing a published dissertation or thesis from a database, citing a thesis or dissertation published online but not from a database, citing a thesis or dissertation: reference overview, what you need.

Since unpublished theses can usually only be sourced in print form from a university library, the correct citation structure includes the university name where the publisher element usually goes.

Author’s last name, F. M. (Year published). Title in sentence case [Unpublished degree type thesis or dissertation]. Name of institution.

Ames, J. H., & Doughty, L. H. (1911). The proposed plans for the Iowa State College athletic field including the design of a reinforced concrete grandstand and wall [Unpublished bachelor’s thesis]. Iowa State University.

In-text citation example:

• Parenthetical :  (Ames & Doughty, 1911)
• Narrative :  Ames & Doughty (1911)

If a thesis or dissertation has been published and is found on a database, then follow the structure below. It’s similar to the format for an unpublished dissertation/thesis, but with a few differences:

• The institution is presented in brackets after the title
• The archive or database name is included

Author’s last name, F. M. (Year published). Title in sentence case (Publication or Document No.) [Degree type thesis or dissertation, Name of institution]. Database name.

Examples 1:

Knight, K. A. (2011). Media epidemics: Viral structures in literature and new media (Accession No. 2013420395) [Doctoral dissertation, University of California, Santa Barbara]. ProQuest Dissertations Publishing.

Trotman, J.B. (2018). New insights into the biochemistry and cell biology of RNA recapping (Document No. osu1523896565730483) [Doctoral dissertation, Ohio State University]. OhioLINK Electronic Theses & Dissertations Center.

In the example given above, the dissertation is presented with a Document Number (Document No.). Sometimes called a database number or publication number, this is the identifier that is used by the database’s indexing system. If the database you are using provides you with such a number, then include it directly after the work’s title in parentheses.

If you are interested in learning more about how to handle works that were accessed via academic research databases, see Section 9.3 of the Publication Manual.

In-text citation examples :

• Parenthetical citation : (Trotman, 2018)
• Narrative citation : Trotman (2018)

Author’s last name, F. M. (Year Published). Title in sentence case [Degree type thesis or dissertation, Name of institution]. Name of archive or collection. URL

Kim, O. (2019). Soviet tableau: cinema and history under late socialism [Doctoral dissertation, University of Pittsburgh]. Institutional Repository at the University of Pittsburgh. https://d-scholarship.pitt.edu/37669/7/Olga%20Kim%20Final%20ETD.pdf

Stiles, T. W. (2001). Doing science: Teachers’ authentic experiences at the Lone Star Dinosaur Field Institute [Master’s thesis, Texas A&M University]. OAKTrust. https://hdl.handle.net/1969.1/ETD-TAMU-2001-THESIS-S745

It is important to note that not every thesis or dissertation published online will be associated with a specific archive or collection. If the work is published on a private website, provide only the URL as the source element.

In-text citation examples:

• Parenthetical citation : (Kim, 2019)
• Narrative citation : Kim (2019)
• Parenthetical citation : (Stiles, 2001)
• Narrative citation : Stiles (2001)

We hope that the information provided here will serve as an effective guide for your research. If you’re looking for even more citation info, visit EasyBib.com for a comprehensive collection of educational materials covering multiple source types.

If you’re citing a variety of different sources, consider taking the EasyBib citation generator for a spin. It can help you cite easily and offers citation forms for several different kinds of sources.

To start things off, let’s take a look at the different types of literature that are classified under Chapter 10.6 of the Publication Manual :

• Undergraduate thesis
• Master’s thesis
• Doctoral dissertation

You will need to know which type you are citing. You’ll also need to know if it is published or unpublished .

When you decide to cite a dissertation or thesis, you’ll need to look for the following information to use in your citation:

• Author’s last name, and first and middle initials
• Year published
• Title of thesis or dissertation
• If it is unpublished
• Publication or document number (if applicable; for published work)
• Degree type (bachelor’s, master’s, doctoral)
• Thesis or dissertation
• Name of institution awarding degree
• DOI (https://doi.org/xxxxx) or URL (if applicable)

Since theses and dissertations are directly linked to educational degrees, it is necessary to list the name of the associated institution; i.e., the college, university, or school that is awarding the associated degree.

To get an idea of the proper form, take a look at the examples below. There are three outlined scenarios:

• Unpublished thesis or dissertation
• Published thesis or dissertation from a database
• Thesis or dissertation published online but not from a database

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 .

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.

Plagiarism means passing off someone else’s words or ideas as your own. It’s a serious offense in academia. Universities use plagiarism checking software to scan your paper and identify any similarities to other texts.

When you’re dealing with a lot of sources, it’s easy to make mistakes that could constitute accidental plagiarism. For example, you might forget to add a citation after a quote, or paraphrase a source in a way that’s too close to the original text.

Using a plagiarism checker yourself before you submit your work can help you spot these mistakes before they get you in trouble. Based on the results, you can add any missing citations and rephrase your text where necessary.

At college level, you must properly cite your sources in all essays , research papers , and other academic texts (except exams and in-class exercises).

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.

Basic Principles of Citation

APA Style uses the author–date citation system , in which a brief in-text citation directs readers to a full reference list entry. The in-text citation appears within the body of the paper (or in a table, figure, footnote, or appendix) and briefly identifies the cited work by its author and date of publication. This enables readers to locate the corresponding entry in the alphabetical reference list at the end of the paper.

Each work cited must appear in the reference list, and each work in the reference list must be cited in the text (or in a table, figure, footnote, or appendix).

Both paraphrases and quotations require citations.

The following are guidelines to follow when writing in-text citations:

• Ensure that the spelling of author names and the publication dates in reference list entries match those in the corresponding in-text citations.
• Cite only works that you have read and ideas that you have incorporated into your writing. The works you cite may provide key background information, support or dispute your thesis, or offer critical definitions and data.
• Readers may find a long string of citations difficult to understand, especially if they are using assistive technology such as a screen reader; therefore, include only those citations needed to support your immediate point.
• Cite primary sources when possible, and cite secondary sources sparingly.
• Cite sources to document all facts and figures that you mention that are not common knowledge.
• To cite a specific part of a source , provide an author–date citation for the work plus information about the specific part.
• Even when sources cannot be retrieved (e.g., because they are personal communications ), still credit them in the text (however, avoid using online sources that are no longer recoverable).

Basic principles of citation are covered in the seventh edition APA Style manuals in the Publication Manual Sections 8.1 to 8.36 and the Concise Guide Sections 8.1 to 8.34
