Our vast collections bring the rich documentary legacy of Colorado's past to researchers here and around the world. Our newspaper collection alone—the largest in Colorado—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 to discover new story ideas.
Our librarians, archivists, curators, and collection managers have assisted students, historians, reporters, and movie producers with questions ranging from the colors of the Colorado state flag to the fine points of early territorial maps.
Our documentary holdings include books, maps, architectural drawings, private and business correspondence, family albums, photographic prints, magazines and newspapers, and a wealth of other historical resources.
While our documents cannot be accessed online, the library's catalog, other indexes, and research services may allow remote researchers to locate the right document, collection, or historical fact.
Most of the collection is readily available in the Library & Research Center. However, the following formats are not immediately available:
