The majority of citation information may be found on a book's copyright page. This is also where the bibliographic record for the work can usually be found. In addition to the copyright page, other places where you might find citation information include the inside front cover, the back cover, and the title page. The information contained on these pages will vary depending on which part of the book they are in but will always include the author(s), the title of the work, and its publication information such as the year published and publisher. Citation details may also be included in the text of the work itself. If so, this would be indicated by italicizing certain words or phrases. These could include names, titles, locations, dates, or any other facts that would help identify the source of information written within the text of the work. Books are often cited using the first word of the sentence followed by "et al." (and including space after the et). For example, if the book was published in 2000 by Wiley Publishing, Inc., then it would be cited as Smith et al., 2000. If the book had more than one author, each would need to be listed separately with their own period at the end.
