Citing a book requires in-text citations and a reference list, also known as a works cited page or bibliography. There are three common citation styles:
APA: APA style citations include the author's last name and first initials, year of publication, italicized book title, and publisher. Meanwhile, the in-text citation includes the author's last name, publication year, and page number.
MLA: An MLA citation requires the author's name, italicized book title, publisher, and year of publication. The in-text citation only lists the author's last name and page number of the cited book.
Chicago-style: Chicago-style citations use footnotes to cite sources instead of parentheticals. The footnotes include the author's name, book title, edition, location and name of the publisher, and the publication year.
Which citation style you use may depend on your course's specific guidelines, but typically APA style is used in social and behavioral sciences, MLA is used in humanities subjects like English literature, and Chicago-style is used in history and humanities.
