When you can't find your books in the WashU Library, Mobius, and Worldcat, another option to obtaining affordable textbooks is to search textbooks websites that offer bargain basement prices for new, used, online, and rented textbooks. Here you might find prices that are more conducive to your budget.

Selected Popular Textbook Price Comparison Websites - (Recommended by Students)

The best way to search these sites is to use the ISBN number or the complete title or the author(s).

Tip: Use the ISBN number (if available). The ISBN number is the unique number assigned to each book. It ensures that the book is the exact one assigned by your instructor. The title, author, year, edition and publisher, match the ISBN number.
