  • "Colorado State Archives Finding Aids Quick Index" - A Project of the Colorado Council of Genealogical Societies. Click on the link to download the index. The Colorado State Archives maintains records from the State and Territory of Colorado, counties, mu­nicipalities, special districts, private entities and a few federal agencies. Many of their records have been indexed and can be searched through the Historical Records Da­tabase. Each of the record sets that are available in the database has a description that should help you decide if an individual record will have the information you are looking for. Many more record sets have not been indexed to date. This list of our holdings will help you get an idea of what’s available.
