If you searched for “how to in text citation a book apa”, you want to know how to cite a book inside your essay or research paper using APA style. In-text citations in APA tell your reader exactly which source supports a claim, and they link directly to the full reference at the end of your paper. This guide walks you through the basic format, citations for one author, two authors, and three or more authors, and the common mistakes to avoid.
The Basic APA In-Text Citation Format
An APA in-text citation for a book has two parts: the author’s surname and the year of publication. In a parenthetical citation, both go inside brackets at the end of the sentence, like this: (Smith, 2020). In a narrative citation, the author’s name appears in the sentence itself and only the year goes in brackets: Smith (2020) argues that reading habits shape memory.
When you quote directly from a book, you must also include the page number: (Smith, 2020, p. 45). For a quotation that spans several pages, use pp. instead of p., for example (Smith, 2020, pp. 45-47). Page numbers are not required for paraphrases, but they are always required for direct quotations.
Citing a Book With One Author
A book with a single author is the simplest case. Use the author’s surname and the year every time you refer to the work. The first time you cite it and every later time, the format stays the same. There is no need to shorten or change it.
For example, if you paraphrase an idea from a book by Johnson published in 2019, you would write (Johnson, 2019). If you quote a sentence from page 112, you would write (Johnson, 2019, p. 112). The full details of the book then appear in your reference list at the end of the paper.
Citing a Book With Two Authors
When a book has two authors, name both authors every time you cite it. In a parenthetical citation, join the names with an ampersand: (Johnson & Lee, 2021). In a narrative citation, use the word “and”: Johnson and Lee (2021) found that study groups improve exam scores.
This rule applies in the seventh edition of APA style, which is the current edition used by most universities. Earlier editions shortened citations after the first mention, but the seventh edition keeps both names throughout, which is simpler and clearer for readers.
Citing a Book With Three or More Authors
For a book with three or more authors, use only the first author’s surname followed by “et al.” from the very first citation. A parenthetical citation looks like this: (Garcia et al., 2022). A narrative citation looks like this: Garcia et al. (2022) describe the method in detail.
The abbreviation “et al.” is Latin for “and others”, and it always ends with a full stop after “al.”. Do not italicise it in APA style. In your reference list, however, you must list up to twenty authors in full before using an ellipsis, so the reference entry is longer than the in-text citation.
Citing Edited Books and Book Chapters
Sometimes you cite a chapter written by one author inside a book edited by someone else. In that case, your in-text citation names the chapter author, not the editor. For example, a chapter by Patel in a book edited by Williams would be cited as (Patel, 2023).
If you refer to the whole edited book rather than a single chapter, cite the editors instead, with “Eds.” noted in the reference list entry. In the text itself, the citation looks the same as any other author citation: (Williams, 2023). The distinction matters mainly in the reference list, where the editor’s role is shown.
Common APA Citation Mistakes to Avoid
One common mistake is forgetting the year. Every APA in-text citation needs a year, even when the author’s name is in the sentence. Another is using the author’s first name or initials in the text; APA uses surnames only. A third is placing the citation after the full stop instead of before it. The citation belongs inside the sentence, before the final full stop.
Students also sometimes cite a book they have not actually read, having only seen it quoted in another source. In that case, APA asks you to cite the secondary source: mention the original author in the text and cite the source you actually read in brackets, for example (as cited in Lee, 2021). Use secondary citations sparingly, and always try to read the original.
APA Book In-Text Citation Examples
| Situation | Parenthetical | Narrative |
|---|---|---|
| One author | (Smith, 2020) | Smith (2020) |
| Two authors | (Johnson & Lee, 2021) | Johnson and Lee (2021) |
| Three or more authors | (Garcia et al., 2022) | Garcia et al. (2022) |
| Direct quotation | (Smith, 2020, p. 45) | Smith (2020, p. 45) |
| Chapter in edited book | (Patel, 2023) | Patel (2023) |
Citing Ebooks and Translated Books in APA
Books now come in many formats, and APA treats most of them the same in the text. An ebook, an audiobook, or a print book by the same author is cited identically in the body of your paper: author and year, with a page or location marker for quotations. For ebooks without fixed page numbers, use a chapter number, section heading, or paragraph number instead, for example (Smith, 2020, Chapter 4) or (Smith, 2020, para. 3). The goal is always the same: help your reader find the exact passage.
Translated books follow a similar pattern. In the text, cite the author of the original work and the year of the translation you used, for example (Garcia Marquez, 2003). The reference list entry then shows the translator and the original publication year, so readers can trace the work back to its source. If you discuss the translation itself, for instance comparing two translations of the same novel, mention the translator in your text as well, so the reader knows which version you mean.
Republished books and new editions also need care. Cite the year of the edition you actually consulted, not the year of the first edition, because page numbers and content may have changed. If the edition matters to your argument, name it in your text: “In the third edition, Smith (2020) revises the earlier claim.” This small detail prevents confusion when a reader opens a different edition and cannot find your quotation.
Building the Matching Reference List Entry
Every in-text citation must match a full entry in your reference list, and the reference list entry for a book follows a fixed pattern: author surname and initials, year in brackets, book title in italics and sentence case, and publisher. For example: Smith, J. (2020). The reading mind. Academic Press. The in-text citation (Smith, 2020) is simply the shortest possible pointer to this entry.
Getting the reference entry right matters because markers and readers check citations both ways. A citation in the text with no matching reference looks like an error, and a reference with no citation in the text looks like padding. Before submitting, cross-check the two lists: every name and year in the text should appear in the reference list, and every reference should be cited at least once. Reference management software can automate this check, but a manual read-through of a short paper takes only a few minutes and catches mistakes that software sometimes misses, such as two authors with the same surname.
A Quick Checklist Before You Submit
Before submitting any paper, run through a short citation checklist. First, confirm that every in-text citation has a matching reference list entry, and that the author names and years agree exactly. Second, check that direct quotations include page numbers or location markers. Third, confirm that et al. is used only for three or more authors, and that two-author citations name both authors every time. Fourth, read each narrative citation aloud to make sure the grammar still works with the year in brackets. These four checks catch the large majority of citation errors, and they take only a few minutes even for a long paper.
What ‘how to in text citation a book apa’ Means
Students search for this term when an assignment requires APA style and a book source must be cited inside the text.

When in doubt, check your institution’s own APA guide, since departments occasionally add local requirements.
Frequently Asked Questions
Do I need a page number when paraphrasing a book in APA?
No. Page numbers are required only for direct quotations. For paraphrases, the author and year are enough, although adding a page number can help readers find the passage.
How do I cite a book with no author in APA?
Use the first few words of the book title in place of the author, in italics if the title is italicised in the reference list. For example: (A Guide to Gardening, 2018).
What if two books by the same author share a year?
Add a lowercase letter after the year, in the order the books appear in your reference list: (Smith, 2020a) and (Smith, 2020b).
Conclusion
Learning how to do an in-text citation for a book in APA comes down to three pieces of information: the author’s surname, the year, and, for quotations, the page number. One author or two, name them all; three or more, use the first name plus et al. Keep these patterns in mind, match every in-text citation to a reference list entry, and your academic writing will meet APA standards with confidence.
