Your faculty director will contact you with information about where to buy textbooks. Some books will need to be purchased overseas. For books that need to be purchased in the U.S. before you depart, go to the UD bookstore website (http://www.udel.edu/bookstore) and search for your courses by their course numbers and sections. This site will give you titles, price and availability of all required textbooks in addition to letting you shop on-line. Books and shipping can be paid for via credit card and will be sent to you. If you'd prefer to buy your books in person, stop in at the UD bookstore.
Students from other universities, before you can purchase textbooks, you'll need the numbers and section codes for the courses you'd like to take. Your contact in CFIS or FLL will send this to you via email.
