About this Database:
The Colorado State Archives is endeavoring to provide on-line indexes to many of our collections. This searchable database is an effort to provide an index that is searchable by name, record type or by time span. It will be especially valuable to researchers and family historians. New indexes will be added periodically to the database. Many of these indexes can also be found on our On-line Indexes page.

The indexes have been compiled from original sources at the State Archives. We cannot be responsible for omissions or errors in the original records nor can we "fix" the indexes that were compiled from the original records unless it was a transcription error. An earnest effort was made to transcribe each name correctly. However, some of the handwritten entries were hard to read, making it difficult to ensure that the spelling of the name is accurate. Please check similar or closely spelled names, as this may help you in your search. If you suspect that a name has been transcribed onto the database erroneously, please let us know and we will check the original record.

In most cases the records from which the indexes were compiled will have more information than what is on the index entry. The Records Description List will help you decide if the records may have the additional information that you need.

We do have search, handling, and copy fees. Please contact us in order to find out the charges for your request or follow the instructions on the Index
Search Page to submit a request from there.
