Students, staff and faculty who are currently enrolled or employed at CU Boulder may use our Interlibrary Loan (ILL) services to request materials. Materials available for request include electronic copies of articles, physical books, microformats and other media. More details about our interlibrary loan service, including available formats, how to request, ILL delivery and renewals, are available via our Interlibrary Loan at CU Boulder page.  

Other affiliates (visiting scholars, etc.) may also be eligible for ILL services according to our borrowing privileges by patron type. Contact for more information. 

Place requests using our ILLiad software. First time users of ILLiad will be asked for some registration information.

Prospector & MOBIUS Borrowing Update
Due to our planned library catalog system migration this summer, borrowing through Prospector and MOBIUS will be paused effective May 19. We expect to be able to resume service for Spring 2024.

Lending to other libraries

We provide interlibrary lending services to libraries and other agencies. Individuals should contact their nearest library to request from us.

Institutions may send requests electronically through OCLC or our ILLiad lending portal. First time lending partners should request login credentials. (More information about lending policies for other libraries)
