From Library Search, type words related to your topic into the main search box. You can limit results to books using the left menu. When you find books that look relevant, click on the title, then click on relevant Subject links for similar titles.
Book reviews can give you important information about significant studies on your topic. Reading what other scholars say about a book will help you quickly evaluate its usefulness and its authority, and give you a summary of the findings or the argument. To find book reviews, enter the title of the book in the library homepage search box, then choose "Articles & More" (this will exclude the actual book and just give you articles about the book).
