<human>:  How do I properly cite a book in my essay?
<bot>: To properly cite a book in your essay, you should include the author’s last name, the year the book was published, and the page number of the quote or reference you are citing. For example, if you wanted to cite a quote from J.K. Rowling’s book, Harry Potter and the Sorcerer's Stone, you would write (Rowling, 1997, p. 23).
