How to find your Textbooks: Your course textbooks have been carefully placed on the shelves by: First, alphabetically, by department acronym. Second, numerically, by course number and, finally, by section number. For instance, the first books on our shelves will begin with all the ACCT classes, followed by ARTS, then BIOL and so forth. Be careful to double-check your section number. You do not want to purchase the wrong books.
