Formatting Book Citations
Citations of books in your Reference List should begin with the last name of the book's author, then the author's initials. Next, write the year of publication within parentheses. After the year, list the title of the book in sentence case -- only capitalize the first word of the title and subtitle, if applicable, just as if you were writing a sentence. Italicize the title of the book; don't underline it or any other part of the citation. Finally, list the location, followed by a colon, and then the publisher.
In-Text vs. Citation
You should also italicize the title of a book when you refer to it within the text of your paper. Unlike in your Reference List, however, the title of a book within the text should be in title case. That means you should capitalize the first word of the title and subtitle; all nouns, pronouns, adjectives, verbs and adverbs; and all words that are four letters or longer. For example, within the text of your paper, you would write "Diagnostic and Statistical Manual of Mental Disorders," but in your Reference List, you would write "Diagnostic and statistical manual of mental disorders."
