The Archives of Special Collections and Archives contain more than 1500 collections and 50,000 linear feet of materials, including manuscripts, correspondence, files, diaries, photographs, posters, newspapers and published works. Established in 1917, the Archives holds internationally renowned manuscript, photograph, records and media collections relating to Colorado, the Rocky Mountain West and transnational subjects. It also serves as a repository for the records of the University of Colorado Boulder.


We have more than 1500 collections and most have finding aids. You can find abstracts of these collections in A Guide to the Manuscript Collections.

Please note that many materials housed in the Archives do not have online records in the Libraries' catalog.  Access to those materials is provided here on this site, and in the card catalog and finding guides kept in the SCA reading room. Finding aids can also be located in the Rocky Mountain Online Archive (RMOA).


There are numerous photographs, films, artwork and audio/video materials located within many of our collections. We're constantly working on providing easy access to them through our CU's Digital Library. However, many of these images remain in their original form.  Please contact sca@colorado.edu to learn more about how to locate them within our collections.


SCA staff will conduct up to one hour of research toward your inquiry. If your request is extensive and you cannot come to SCA to conduct research, we recommend that you hire an outside researcher to aid you in your inquiries.
