To renew a book, use the "My Library Account" link on the homepage, or sign in to Search@UW. From there you can view your library fines (if any), see what books you have checked out with their due dates, and renew materials.
Interlibrary loan renewals are done within your Interlibrary Loan Account.
During busy times and after hours, other librarians from our chat consortium will help you. Have a non-library question? See Contact UWM and Campus IT Support.
