What is the proper keyword format for citing a book in an academic paper?

There's no single "keyword format" for citing a book in an academic paper. The format depends entirely on the citation style you're required to use. Different styles (MLA, APA, Chicago, etc.) have different requirements for punctuation, order of information, and even the specific pieces of information included.

However, the information typically included in a book citation regardless of style includes:

* Author's name(s): Last name, First initial. Middle initial if available.

* Book title: Usually italicized.

* Edition (if not the first): e.g., 2nd ed.

* Publisher:

* Publication date: Year.

* Location of publisher: (Often city and state, or sometimes just city).

Examples in different styles:

To illustrate the differences, let's use the following hypothetical book:

* Author: Jane Doe

* Title: *The History of Widgets*

* Edition: 3rd edition

* Publisher: Acme Publishing

* Publication Date: 2023

* Location: New York, NY

APA (7th edition):

Doe, J. (2023). *The history of widgets* (3rd ed.). Acme Publishing.

MLA (9th edition):

Doe, Jane. *The History of Widgets*. 3rd ed., Acme Publishing, 2023.

Chicago (author-date):

Doe, Jane. 2023. *The History of Widgets*. 3rd ed. New York, NY: Acme Publishing.

Chicago (notes and bibliography):

[1] Jane Doe, *The History of Widgets*, 3rd ed. (New York, NY: Acme Publishing, 2023), [page number if citing a specific page].

As you can see, the same information is presented differently depending on the style guide. You MUST consult the specific style guide (often a style manual or guide provided by your institution or professor) to learn the correct format for your paper. There are many online resources and style guides available to help you with this.
