History Colorado's Archives collection includes books, manuscript collections, maps and atlases, architectural drawings, newspapers, serial publications and directories, oral histories, sound recordings and transcriptions, and ephemera and subject collections. The collection is particularly strong on subjects relating to early immigration and migration, mining, railroads, and the documentation of the mid-nineteenth century population boom, the growth of cities, and continued migration to Colorado.

Archival materials are available for research at the Hart Research Library. More information on archival collections can be found by searching our online collection catalogs.
