What's New

We would like to acknowledge the incredible indexing work of Gerald Sherard, Connie and Jesse Ryan. These volunteers have been tireless for us and have added most significantly to our Historical Records Database. Our database, at almost 900,000 entries, would not be what it is without them! Thank you so much!

These web pages have been added to our site or significantly modified to improve public access to Colorado's archival records:

October 27, 2009 - Since April, 2009 we have put almost 100,000 more entries into our Historical Records Database. Notable indexes include the Denver Birth and Death Indexes from 1906-1909; non-fatal mine accidents 1883-1900, probate records from several counties, school census records for several school districts including Dearfield, which was a black colony established in 1910; and business incorporations (66,000 entries). We now have 870,363 entries in our database. We are endeavoring to put more school census, probate, and naturalization indexes up as well as other miscellaneous lists.

April 3, 2009 - We have begun to put naturalization indexes onto the Historical Records Database. Just completed is the Larimer County index that spans 1885-1958. We plan on adding additional indexes in the near future for other counties. As of this date we have 773,933 entries in the database.

February, 2009 - We have processed almost 200,000 entries from the Arapahoe County/Denver Lot and Block Index into the Historical Records Database. The index documents property ownership from 1862-1917 in the Denver area. The index, itself, can help researchers find information about particular property and the owners in the time period. It also refers to the deed books where the actual deed is recorded. It is an invaluable index for house/neighborhood historians.

February 9, 2009 - 98 Mine Location Certificate entries were added to the Historical Records Database. These document mining claims on State land from 1905-1910.

January 5, 2009 - 1442 entries were added to the Historical Records Database from Summit County probate records.

January 1, 2009 -- An interesting record group originating with the Secretary of State's Office (licensing) exists. It is the Record of  Prohibition arrests made during the Roaring Twenties when prohibition was causing many people to go underground with their liquorous pursuits. We have uploaded the index to this record series onto the Historical Records Database.

January 1, 2009 -- The Historical Records Database  now has over 566,000 entries. We will be adding numerous records, especially probate indexes in the near future.
