OCLC code: COD 

CU Boulder provides interlibrary lending services to libraries and other agencies. Individuals affiliated with CU Boulder are eligible for our Interlibrary Loan/Document Delivery services for borrowing from other libraries. Other individuals should contact their local public library or university-affiliated library to request from us.

Lending to libraries and organizations outside the CU System

Institutions may send requests electronically through OCLC (OCLC Symbol: COD) or our ILLiad lending portal: https://colorado.illiad.oclc.org/illiad/COD/Lending/LendingLogon.html

Colorado institutions that do not use OCLC may work with us directly to enable lending and borrowing. First time users should contact us at cu-ill@colorado.edu to verify that you do not already have an account, and to request login credentials. Thereafter, those institutions may log in to request loans or scans via our ILLiad lender portal.

Formats and lending limits

We lend most formats to libraries and organizations. Institutions may request digital scans of up to 100 pages; book loans; theses and dissertations; most newspapers; maps; government publications, DVDs and VHS tapes. Dissertations dated 2005 and newer may only be available for purchase through ProQuest. Six volumes of a multi-volume set or reels of microfilm may be requested on one request.
