Prospector & MOBIUS Borrowing Update
Due to our library catalog system migration, borrowing through Prospector and MOBIUS has been paused. We are working closely with our partners to resume these services. Until they are resumed, you may be eligible to continue to request through Prospector if you are affiliated with other participating libraries, which include many Colorado public libraries.

Through this service, current CU-Boulder faculty, staff and students may borrow materials through Prospector and MOBIUS consortial catalogs at no cost.

  • 70 items may be requested at a time.
  • Prospector/MOBIUS requests should take three to five working days for materials to arrive.
  • Materials may be picked up and returned only at Norlin or one of the branch libraries.
  • Lost materials will cost $100 ($75 lost book fee plus $25 processing charge).
  • Books check out for three weeks with one renewal allowed; Media (DVDs, CDs, videos and sound recordings) check out for one week with no renewals.
  • PASCAL bound journals check out for one week with no renewals.*

*There’s a $400 lost volume fee for PASCAL journals.
