Digital Volunteering

Transcribing the Collection

Join our digital volunteer network on Zooniverse and help us transcribe documents. As a way to make our collection more accessible, this work will create additional resources and knowledge about Colorado history and will have significant impact for researchers throughout the world. 


Out of the Archives

This project includes 10 sets of record-keeping ledgers for the archive collection. History Colorado has collected for over 140 years and holds millions of archive items including approximately 30,000 books, 3,000 maps, and other unique items and each has a corresponding entry in one of these ledgers. These ledgers date back to the early 1900s and are History Colorado's first records for the archive collections and contain information about when they came in, from whom, and other pertinent data. Help us transcribe each one of these ledgers so we can better preserve these ledgers and match the provenance to each item.
