Prospector: The Colorado Unified Catalog
Prospector is a unified catalog of sixteen academic, public and special libraries in Colorado and Wyoming. If Penrose 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 Penrose Library in just two-four days. Whenever possible, use Propsector instead of Interlibrary Loan to request books. Articles are not available through this service.
The world's largest bibliographic database presents bibliographic records for books, serials (journals), and all other formats. Use WorldCat to find materials not in University Libraries or Prospector.
