Interlibrary Loan

Regis University Library – Resource Sharing Services  


Prospector is our regional borrowing and lending group and includes major academic and public libraries in Colorado as well as the University of Wyoming.  Use this service to request print books, CDs, DVDs, and more!  To view your Prospector requests (and regular Regis loans), please visit your library account. 

Interlibrary Loan (ILL)  

If something is not available locally, use ILL to request items from around the world!  This service can be used to request books, media, articles, and book chapters.   ILL requests are made through ILLiad, the library’s interlibrary loan management system.   

Delivery of Items  

For current students, faculty, and staff within a 12-mile radius of any Regis University campus, physical items can be picked up at your campus of choice.  For the northwest Denver campus, items will be held at the library’s circulation desk for 10 days.   For the Thornton campus, items can be picked up at the front desk.  Please allow up to 7 days for delivery to the Thornton campus. 

For current students, faculty, and staff further than 12 miles from any Regis campus, the library will mail Regis and interlibrary loan items to a home or work address.  The library will pay for shipping to the address. Users are responsible for return shipping costs. Only ILL and Regis items will be mailed. Prospector items must be picked up at a Regis campus location.    

All electronic requests (articles, book chapters, and streaming media) will be delivered electronically to the email provided in your ILL account.

User Responsibilities

Eligibility for ILL services is dependent upon good standing across all library accounts.   Overdue items or fines/fees for any library services will result in a temporary block on your ILL, Prospector, and local account.  This block can be resolved by returning materials and/or paying any fines and fees.    

Users are responsible for all materials on their account and may be charged the cost of replacement or repair for lost or damaged items. For students, charges will be added to your student account.  For faculty and staff, the library will invoice you the amount charged by the lending library.  Non-payment may result in the loss of library privileges.   Questions regarding replacement or repair costs should be directed to the Access Services Librarian.
