APA Bibliography: complete guide for your thesis or dissertation

The APA bibliography is one of the most common sources of stress for master’s and doctoral students. You have spent months (sometimes years) on your research, and now you have to format dozens of references according to precise rules, at the risk of losing marks or having to rework your document before the final submission.

This guide explains everything you need to know about the APA bibliography (7th edition): in-text citations, reference list, concrete examples and mistakes to avoid.

Why is the APA bibliography essential in a thesis?

Bibliographic rigour is a non-negotiable academic requirement. A well-built bibliography:

  • Adds credibility to your work by showing that your arguments rest on reliable sources
  • Protects against plagiarism by clearly attributing each idea to its author
  • Makes verification easier for the members of your committee and for readers who want to dig deeper into your topic
  • Meets your institution’s requirements: several graduate studies faculties check bibliographic compliance before accepting the final submission

Among the common bibliographic styles (APA, MLA, Chicago, Vancouver), APA (American Psychological Association) is the dominant standard in the social sciences, psychology, education and many related disciplines.

APA standards, 7th edition: what changed

The 7th edition of the APA manual, published in 2019, brings several important changes compared with the 6th edition:

  • Up to 20 authors can be listed in a reference (compared with 6 previously)
  • DOIs are now active hyperlinks: https://doi.org/10.xxxx
  • The place of publication has been removed for books
  • Publisher names are simplified (you drop “Inc.”, “Ltd.”, and so on)
  • Journal and newspaper titles stay in italics with a capital letter on each important word

If your supervisor or your institution still uses the 6th edition, check before you begin.

In-text citations (parenthetical): rules and examples

The APA bibliography works with an author-date system: each source cited in the text is accompanied by a short parenthetical reference that points to the full reference list at the end of the document.

Basic format

SituationFormatExample
One author(Name, year)(Tremblay, 2021)
Two authors(Name1 & Name2, year)(Martin & Bouchard, 2020)
Three authors or more(First name et al., year)(Dupont et al., 2019)
Direct quotation(Name, year, p. X)(Lefebvre, 2022, p. 45)
Organization as author(Acronym or name, year)(WHO, 2023)

Direct quotations vs paraphrasing

Direct quotation: reproduces the exact words of the source, in quotation marks:

“Working memory plays a central role in learning processes” (Gauthier, 2021, p. 73).

Paraphrase: restates the idea in your own words, without quotation marks:

Learning processes depend largely on working memory (Gauthier, 2021).

Reference list: format and examples

The APA reference list goes at the end of the document, on a new page titled References (not “Bibliography” or “Bibliography and references”). It must be:

  • Sorted alphabetically by the first author’s last name
  • With a hanging indent of 1.27 cm for each entry
  • In double spacing throughout

Common mistakes and how to avoid them

Even rigorous students make these mistakes in their APA bibliography:

1. Mixing APA editions

Using both the 6th and 7th editions in the same document creates inconsistencies. Choose one edition from the start and stick with it.

2. Forgetting the DOI or using the wrong format

In APA 7, DOIs must appear as a hyperlink: https://doi.org/10.xxxx. A missing or badly formatted DOI is a frequent error during automated verification.

3. Incorrect capitalization of titles

In APA, only the first word of the title, the first word after a colon, and proper nouns take a capital letter in the titles of articles and books. Journal titles, on the other hand, keep capital letters on each important word.

Incorrect: “The Effects of Anxiety on Academic Performance” Correct: “The effects of anxiety on academic performance”

4. Confusing “and” and ”&”

In parenthetical citations in English, some writers use “and”, but APA uses ”&” between authors. Check your institution’s policy: some allow “and” in the running text, but the reference list always uses ”&“.

5. References in the list but not in the text (and vice versa)

Every source cited in the text must appear in the reference list. Every entry in the reference list must have at least one citation in the text. Any discrepancy will be flagged by verification software.

6. Forgotten spacing and hanging indent

The formatting of the reference list is just as important as its content. The hanging indent and double spacing are part of the APA standards.

Tools to automate your APA citations

Managing dozens or hundreds of references by hand is a source of errors. These tools will save you precious time:

Zotero (free)

The most popular reference manager in academia. Zotero automatically detects bibliographic information on web pages and in PDFs, generates APA citations with one click, and syncs with Word or LibreOffice.

Mendeley (free)

An alternative to Zotero, developed by Elsevier. Similar features, with an emphasis on sharing libraries among members of a team.

Citation Machine / BibGuru

Online tools to quickly generate APA references from a DOI, an ISBN or a URL. Handy for a one-off source, less suited to managing a complete bibliography.

Uniformat

Uniformat goes further than simple reference management: it checks the overall compliance of your thesis or dissertation with your institution’s requirements, including the APA bibliography. If an entry does not follow the standards, or if an in-text citation has no matching reference, Uniformat detects it automatically.
