Colorado Historic Newspapers Collection This link opens in a new windowA service of the Colorado State Library, the Colorado Historic Newspapers Collection (CHNC) currently includes more than 2.9 million digitized pages, representing more than 650 individual newspaper titles published in Colorado from 1859 up thru 2022. Due to copyright restrictions, the CHNC does not always include newspapers published after 1927, but the CHNC can digitize beyond 1927 if publisher permission can be secured. And best of all the CHNC can be browsed and searched for free!
