You are allowed to check out as many library books as you want, but your loan period as a graduate student is 16 weeks. You can renew books up to 3 times online in your My Library Account. As a graduate student, you may check out books at the J.D. Williams Library and the Science library. (Note: The Science Library houses books with the following subjects: pharmacy, chemistry, biochemistry, and materials related to the natural products center). You may return books to either location as well as an outside "Book Drop" metal bin located on the corner of Dormitory Row North and Dormitory Row West (near Weir Hall). Please do not return videos or Interlibrary Loan materials to the book drop - always bring them to the library to check in.
