Prospector is a unified catalog of sixteen academic, public and special libraries in Colorado and Wyoming. If University Libraries does not own the item or if the item is checked out, with a single search DU Library users can identify and borrow many of the materials from the collections and have them delivered to University Libraries Lending Desk in just two-four days. Whenever possible, use Propsector instead of Interlibrary Loan to request books. Articles are not available through this service.
