Our vast collection brings the rich documentary legacy of Colorado’s past to researchers here and around the world. Our newspaper collection alone—the largest collection of Colorado newspapers anywhere—has helped genealogists to find their ancestors’ birth, marriage, and death records; architectural historians to identify early buildings; lawyers to prepare legal cases; and novelists and filmmakers to discover new story ideas and historical background.
You will find everything from historic maps to teapots, vehicles, and clothing in our collection, as well as a photography collection containing more than a million images dating from as early as the 1850s. Our library also offers free access to Ancestry Library Edition and Newsbank’s historic Colorado newspapers database.
Visitors will primarily encounter librarians in the Hart Research Library. We are also supported by a large department of professionals dedicated to the careful cultivation and preservation of our collection. Our archivists, curators, collection managers, and registrars manage everything from acquisition of collection items to arrangement, processing, cataloging, digitization, physical preservation, and exhibit research and development. They are also available to assist researchers with questions of collection provenance and access to artifact collections not served through the Hart Research Library.
