<human>:  How do I cite a book in MLA format?
<bot>: To cite a book in MLA format, you need to include the author's last name, the title of the book, the publisher, the year of publication, and the page numbers of the citation. For example, if you wanted to cite J.K. Rowling's Harry Potter and the Sorcerer’s Stone, you would include the following: Rowling, J.K. Harry Potter and the Sorcerer’s Stone. Scholastic, 1998.
