Colorado Encyclopedia

The Colorado Encyclopedia is a nationally ranked online reference with more than 700 primary entries about Colorado’s history and culture. Colorado’s 4–12th grade students are one of the Encyclopedia’s primary audiences. Many of the entries are designed for student use, with accompanying resource sets and inquiry cards for their teachers.

In 2019, with funding from the National Endowment for the Humanities and the History Colorado State Historical Fund, the Encyclopedia entered its second phase of development. Several hundred new entries will be added, including a series that focuses on the centennial of Colorado’s 1920 ratification of the 19th Amendment to the U.S. Constitution, which gave all American women the right to vote.

The primary goal of the Colorado Encyclopedia is to “to offer a reliable resource for all those interested in learning about this extraordinary state.”
