How to Cite a Book in APA Format

Referencing can feel confusing, especially when your professor hands back an assignment with marks deducted for incorrect citations. APA (American Psychological Association) format is one of the most widely used citation styles in universities across New Zealand and around the world. Whether you are working on a nursing assignment, a management assignment, or a dissertation, getting your book citations right is non-negotiable. This guide walks you through everything you need to know.

What Is APA Format and Why Does It Matter?

APA format is a set of rules developed by the American Psychological Association for writing and referencing academic work. It is used extensively in social sciences, psychology, nursing, education, and business disciplines.

Why universities require APA:

• It gives credit to original authors and avoids plagiarism
• It allows readers to locate your sources independently
• It shows academic credibility and research depth
• It demonstrates attention to detail — a core academic skill

Students in subjects like social science, economics, and marketing are frequently required to follow APA 7th edition, the current and most up-to-date version.

Understanding APA 7th Edition (Latest Update)

APA released its 7th edition in 2019, and this is the version most NZ universities now follow. The key changes from the 6th edition include:

• Running heads are no longer required for student papers
• Up to 20 authors can be listed before using an ellipsis
• DOI (Digital Object Identifier) is formatted as a hyperlink
• Publisher location is no longer required in book references
• Singular "they" is accepted as a gender-neutral pronoun

Always confirm which edition your university requires before you begin writing. If you are unsure, your thesis assignment help provider or academic supervisor can clarify.

The Basic APA Format for a Book

The standard structure for citing a book in APA 7th edition is:

Author Last Name, First Initial. (Year of Publication). Title of book: Subtitle if any. Publisher.

Example:

Brown, B. (2018). Dare to lead: Brave work, tough conversations, whole hearts. Random House.

Key rules to remember:

• Only the first word of the title and subtitle, and any proper nouns, are capitalised
• The title is italicised
• The year goes in parentheses immediately after the author's name
• No publisher location is needed in APA 7th edition

How to Cite Different Types of Books

Citing a Book with One Author

Format: Author, A. A. (Year). Title of work: Capital letter also for subtitle. Publisher.

Example: Gladwell, M. (2008). Outliers: The story of success. Little, Brown and Company.

Citing a Book with Two Authors

Use an ampersand (&) between author names in the reference list.

Example: Strunk, W., & White, E. B. (1999). The elements of style (4th ed.). Longman.

Citing a Book with Three or More Authors

List all authors up to 20. For 21 or more, list the first 19, then use an ellipsis (…) before the final author's name.

Example: Kotler, P., Kartajaya, H., & Setiawan, I. (2021). Marketing 5.0: Technology for humanity. Wiley.

Citing a Book with an Editor (Not an Author)

When a book has an editor instead of an author, place "(Ed.)" or "(Eds.)" after the editor's name.

Format: Editor, E. E. (Ed.). (Year). Title of book. Publisher.

Example: Smith, J. A. (Ed.). (2020). Qualitative psychology: A practical guide to research methods (3rd ed.). SAGE Publications.

This format is common in computer science assignments and engineering assignments where edited technical handbooks are frequently cited.

Citing a Chapter in an Edited Book

When you cite a specific chapter written by one author within an edited book, use this format:

Format: Chapter Author, A. A. (Year). Title of chapter. In E. E. Editor (Ed.), Title of book (pp. page range). Publisher.

Example: Harman, G. (2019). Object-oriented ontology. In R. Braidotti & M. Hlavajova (Eds.), Posthuman glossary (pp. 289–291). Bloomsbury Academic.

Citing an E-Book or Online Book

For e-books, include a DOI or URL at the end of the reference. No DOI or URL is needed if the e-book was accessed through a general library database.

Example: Dweck, C. S. (2006). Mindset: The new psychology of success. Ballantine Books. https://doi.org/10.XXXX

Citing a Book with No Author

When no author is listed, move the title to the author position.

Example: Merriam-Webster's collegiate dictionary (11th ed.). (2003). Merriam-Webster.

How to Format In-Text Citations for Books

In APA, every time you mention information from a source in your writing, you must include a brief in-text citation alongside the full reference in your reference list.

Basic In-Text Citation Format

(Author Last Name, Year)

• Paraphrase: According to Brown (2018), vulnerability is a core leadership skill.
• Direct quote: "Vulnerability is not winning or losing" (Brown, 2018, p. 4).

In-Text Citation with Two Authors

Always use both names, separated by an ampersand inside parentheses or "and" in running text.

• Example: (Strunk & White, 1999)
• In running text: Strunk and White (1999) argue that brevity is essential.

In-Text Citation with Three or More Authors

Use only the first author's name followed by "et al." from the very first citation.

• Example: (Kotler et al., 2021)

This is particularly important when writing finance assignments or business communication assignments that draw on multiple co-authored textbooks.

Common APA Referencing Mistakes Students Make

Even careful students make errors. Here are the most frequent mistakes to avoid:

• Wrong capitalisation — only the first word of the title (and subtitle) is capitalised, not every major word
• Forgetting italics on the book title
• Using the 6th edition rules when your university requires the 7th
• Adding publisher location — this is no longer required in APA 7th edition
• Incorrect in-text format — missing the year or page number for direct quotes
• Not including DOI for digital or online books
• Listing authors incorrectly — always Last Name, First Initial format

Students working on case study assignments often lose marks on referencing even when their analysis is strong. Correct citation habits can make a significant difference to your final grade.

APA Reference List vs. Bibliography: Know the Difference

Many students confuse these two terms:

In APA format, you always use a Reference List, not a bibliography.

Quick APA Book Citation Checklist

Before submitting your assignment, run through this checklist:

• Author(s) listed as Last Name, First Initial
• Year in parentheses after author
• Book title italicised
• Only first word of title/subtitle capitalised (plus proper nouns)
• Edition number included if not the first edition
• Publisher name listed without location
• DOI or URL added for e-books
• In-text citations match reference list entries
• Reference list is in alphabetical order by author's last name
• Hanging indent applied (second line indented)
