he ASI Book Exchange is a service for CSU Stanislaus students, provided by the Associated Students, Inc. (ASI). ASI Book Exchange gives students the option to buy or sell their new and used books at a discounted price. The Book Exchange is held in the fall and spring semesters every year.

Students submit their new and used books to the ASI Book Exchange for other students to purchase. ASI asks that the books being submitted are priced at least 10-15 % lower than the used book price in the Book Store. Once the book is sold, the student (vendor) receives the full amount for which the book was priced. Book Exchange gives students an opportunity to receive a reasonable refund for their used textbooks, while providing other students with lower priced textbooks.
