An APA citation connects a statement in your paper to the source behind it. Usually, you need two pieces: a short author-and-year citation beside the borrowed idea and a fuller reference entry at the end. Start with the source you actually read, collect its publication details, and build those two pieces together.
This guide follows APA seventh-edition guidance for common books, webpages, and journal articles. All sample authors, titles, publishers, quotations, and publication details below are fictional teaching examples. They demonstrate formatting, not evidence you can cite in an assignment.
How does an in-text citation work?
For one author, a parenthetical citation looks like (Rivera, 2024). A narrative citation makes the author part of your sentence: Rivera (2024) describes several note-taking approaches. The name and year direct the reader to the matching reference entry.
For two authors, write (Rivera & Chen, 2024) in parentheses, but Rivera and Chen (2024) in a sentence. For three or more authors, the usual form is (Rivera et al., 2024), including the first citation. If that abbreviation would make two different sources indistinguishable, include enough names to clarify which one you mean. See APA’s author–date guidance.
Keep the citation close enough to show which idea belongs to the source. A paragraph that switches between your interpretation and several writers’ findings needs clearer attribution than one that discusses a single study throughout.
When do you need a page number?
A paraphrase restates an idea in your own wording and still needs attribution. A page number is optional for an ordinary paraphrase, but useful when directing readers to a particular passage in a long book. APA’s paraphrase guidance explains how to keep attribution clear across several sentences.
A direct quotation needs a locator. Here is a fictional short quotation: “Record the question before collecting the answer” (Rivera, 2024, p. 18). For a passage spanning pages, use “pp.” and the page range. Short quotations take quotation marks; quotations of 40 words or more use an indented block without quotation marks. See the quotation rules for placement and punctuation.
If the source has no page numbers, use an appropriate alternative, such as a paragraph number or a section heading with a paragraph number. For example, a fictional locator might be (Chen, 2025, Planning section, para. 3). Do not invent a page number from your browser’s print preview. APA provides locator examples for unpaginated sources.
How do you build a book reference?
For a straightforward authored book, collect the author, year, title, edition if relevant, and publisher. Put the surname before the initials, italicize the book title, and use sentence case for that title. Include a DOI when the book has one; do not add the publisher’s city. Consult APA’s book examples for edited books and other variations.
Fictional print-book example, with no DOI:
Rivera, L. (2024). Notes that lead to questions (2nd ed.). Cedar Study Press.
The corresponding citation is (Rivera, 2024). Notice that the edition information follows the italicized title but is not italicized itself. A chapter by a different author in an edited collection needs a chapter reference, rather than this whole-book pattern.
How do you reference a webpage?
Identify the credited person or responsible organization, the publication or relevant update date, the page title, the website name, and the URL. The page title is italicized. Omit the website name when it repeats the author. A review date does not necessarily indicate changed content. APA’s webpage examples cover these distinctions.
Fictional webpage template:
Chen, M. (2025, March 6). Planning a library research session. Campus Learning Desk. [Insert the actual page URL]
The bracketed URL instruction is a placeholder to replace, not text to leave in a finished reference. Its in-text citation would be (Chen, 2025), without the month and day. Choose the source category by what the work is: a journal article found online remains a journal article.
How do you reference a journal article?
Record the authors, year, article title, journal name, volume, issue, pages or article number, and DOI when available. The article title uses sentence case without italics. The journal name and volume are italicized; the issue number is not. Compare your entry with APA’s journal article examples.
Fictional print-journal example, with no DOI:
Patel, R., & Moss, J. (2023). Comparing two note-review routines. Journal of Study Practice, 8(2), 21–34.
Its parenthetical citation is (Patel & Moss, 2023). For a real article with a DOI, append the verified DOI in https://doi.org/ format. Never construct an identifier from a title or guess one because a citation generator left that field empty.
What if information is missing?
Check the source before filling gaps. If no author is identifiable, move the title into the author position and cite the title in text. If no date is available, use n.d. in both places. Do not treat the current year as the publication year. APA’s missing-information guide shows combinations of missing elements.
A missing DOI is not automatically an error. A print work without one needs no URL. Many journal articles retrieved from academic databases also omit database URLs when no DOI exists. An article on a public journal website may need its direct URL instead. Follow the DOI and URL guidance for the source type.
Check the source, then check the formatting
Before submitting, compare each reference against the original publication. Match every author spelling and year to its in-text citation, open each link, and verify quotation wording and locators. Treat citation-generator output as a draft: a perfectly punctuated entry can still point to the wrong edition or misidentify a webpage’s author.
