To cite a book, you need two things: a short in‑text citation and a full entry in your bibliography or reference list.

Below are the basics for the three most common styles.

Core details you always need

From the title and copyright pages, note:

  • Author or editor name(s)
  • Year of publication
  • Full title and subtitle
  • Edition (if not the first)
  • Publisher
  • Place of publication (needed in Chicago)

Think of these as the building blocks that each style rearranges differently.

MLA style (often used in humanities)

Works Cited entry

General pattern:

Author last name, First name. Title of the Book. Publisher, Year.

Example:

Austen, Jane. Pride and Prejudice. Penguin Classics, 1813.

Key points:

  • Title in italics, headline capitalization (most main words capitalized).
  • No place of publication required in current MLA.
  • For e‑books, you can add a label like “e‑book” before the publisher if needed.

In‑text citation

Pattern: (Author last name page).

Example: (Austen 52).

If you mention the author in the sentence, just put the page number in parentheses.

APA style (often used in social sciences)

Reference list entry

General pattern for a whole book:

Author last name, Initials. (Year). Title of the book: Subtitle. Publisher.

Key ideas:

  • Only the first word of the title and subtitle and proper nouns are capitalized.
  • Year goes in parentheses right after the author’s name.
  • No city of publication in current APA.

In‑text citation

Basic pattern: (Author last name, Year).

  • Parenthetical: (Smith, 2020).
  • Narrative: Smith (2020) argues that…

If you quote directly, add a page: (Smith, 2020, p. 45).

Chicago style (often used in history and some humanities)

Chicago has two systems: Notes & Bibliography (footnotes) and Author–Date.

Notes & Bibliography – bibliography entry

Pattern for a book:

Author last name, First name. Title of the Book: Subtitle. Place of publication: Publisher, Year.

Example:

Rhys, Jean. Wide Sargasso Sea. London: Penguin, 1996.

You then use footnotes or endnotes that point to this full entry.

Author–Date – reference list entry

Similar to APA:

Author last name, First name. Year. Title of the Book. Place of publication: Publisher.

Example:

Smith, James. 2012. Example Book. New York: Norton.

In‑text, you use (Smith 2012, 45) for a specific page.

Style Reference / Bibliography format In‑text pattern
MLA Author last name, First name. Title of the Book. Publisher, Year. (Author last name page). Example: (Austen 52).
APA Author last name, Initials. (Year). Title of the book: Subtitle. Publisher. (Author last name, Year) or Author last name (Year). Add page for quotes: (Smith, 2020, p. 45).
Chicago (Notes & Bib.) Author last name, First name. Title of the Book: Subtitle. Place of publication: Publisher, Year. Footnote or endnote with full/shortened details; no parenthetical by default.
Chicago (Author–Date) Author last name, First name. Year. Title of the Book. Place of publication: Publisher. (Author last name Year, page). Example: (Smith 2012, 45).

Simple “plug‑and‑play” example

Say your book is:

  • Author: Maria Lopez
  • Year: 2021
  • Title: Urban Futures: Climate and Cities
  • Publisher: Greenleaf Press
  • City: Boston

Your citations would look like:

  • MLA Works Cited:

Lopez, Maria. Urban Futures: Climate and Cities. Greenleaf Press, 2021.

  • APA Reference:

Lopez, M. (2021). Urban futures: Climate and cities. Greenleaf Press.

  • Chicago Bibliography (Notes & Bib.):

Lopez, Maria. Urban Futures: Climate and Cities. Boston: Greenleaf Press, 2021.

Quick checklist so you don’t lose points

Before you submit, check:

  1. Did you include every required element (author, year, title, publisher, and place if needed)?
  2. Did you match capitalization rules for your style?
  3. Are book titles italicized, not in quotes?
  4. Is punctuation (commas, periods, colons) in the right places for your chosen style?
  5. Do your in‑text citations exactly match the entries in your reference list?

If you tell me which style you must use (MLA, APA, or Chicago) and share your book’s details, I can format the exact citation text for you.
