This collection of photographic prints was assembled and arranged by various librarians at the Denver Public Library as a way to increase the accessibility of images prior to the use of computer databases. The collection contains items dating from around 1870 to 2000, with the bulk of the materials dating between 1900 and 1980. Photographs have been arranged into series by subject and then arranged alphabetically. Subjects include: Biographies, Denver, General Subjects, Railroads, States and Cities, and Visual Materials. The Visual Materials index is a new addition covering previously unindexed resources from a collection of late 19th and early 20th century illustrations (mostly woodcuts) and photographs.
