Finding Book Chapters, also called Book Articles:

To find chapters within books, search Library OneSearch with a keyword search on your topic, whether your topic is an idea, a period of history, or a person. A keyword search will search multiple fields of the record for books, such as title, author, contents note, etc.

In the Results list, on the upper left is the Refine Results panel.  Look for Format and click on the orange caret to limit your results by format type, including Books and Book Chapters.

Note: Don't forget to use Bibliographies
