The library has four closed collections: the Colorado Room, the Ruth Marie Colville Room, the Jack Cooper Room, and the Archive Room.
- The Colorado Room contains newspaper clippings, obituary files, and maps related to the San Luis Valley and to Colorado.
- Materials in the Ruth Marie Colville Room trace the history of southern Colorado and northern New Mexico in general, and the San Luis Valley in particular.
- The Jack Cooper Collection was donated to the library upon the death of Jack Kyle Cooper (1932-2006). It is Cooper's personal collection containing over one thousand volumes on a variety of topics, including Colorado history.
- The Archives Collection contains historical materials related to Adams State College, as well as older books.
Because many of these items are unique and cannot be replaced, the library has adopted the following guidelines for the use of these collections to insure their preservation for future use.
- The materials belonging to a closed collection are kept in locked rooms and are not allowed to be checked out from the building. Also, they are not open for browsing.
- Materials may be accessed only by requesting the assistance of a reference librarian. It is recommended patrons make appointments ahead of time in order to insure that a librarian will be available. Call 719-587-7879 to speak with a reference librarian, or send e-mail.
- Up to three items may be retrieved for use at one time.
- If materials are intact and usable (some items are too fragile to use), then these items may be used in the reference area. Permission to photocopy will be granted, or denied, on a case-by-case basis.
- All materials pulled for use will need to be signed out and a current, valid picture ID will be held during their use.
- Exceptions to the above policy must be approved by the library director, David Goetzman. He may be reached by calling 719-587-7820 or by e-mailing him at firstname.lastname@example.org.
