The internet is a powerful tool for finding information—if you can separate the facts from the pants-on-fire lies. That’s why William Wei, a history professor at the University of Colorado Boulder, dreamed up the Colorado Encyclopedia, a website that posts academic-approved accounts of the Centennial State’s past. Funded by a National Endowment for the Humanities grant and the State Historical Fund, the site goes live this month with 500 articles about everything from Denver founder William Larimer Jr. to our state’s history of lynchings. (Sometimes facts are ugly.) Unlike Wikipedia, the Colorado Encyclopedia’s entries are written by experts and vetted by professors from local universities. Moreover, Wei enlisted a veteran educator to write accompanying lesson plans for teachers. The only issue? Explaining what an encyclopedia is to the Google generation.
