Two of the primary digital collections in Colorado which are available online are the Denver Public Library's History and Genealogy Photo Collection and the Colorado Digitization Program, which offers two primary collections:

"Heritage West is a database that brings together thousands of digital objects from the collections of museums, libraries, historical societies and archives from throughout the Western United States. Included in this database are photos, documents, artifacts, costumes, diaries, oral histories and manuscripts representing the West's cultural, scientific and historic heritage."

"Colorado Historic Newspapers Collection (CHNC) currently includes more than 500,000 digitized pages, representing 163 individual newspaper titles published in Colorado from 1859 to 1923. Due to copyright restrictions, CHNC does not generally include newspapers published after 1923."
