Join History Colorado\'s Curator of Archives Shaun Boyd and Denver Public Library\'s Senior Special Collections Librarian Craig Haggit for a lively, fun exploration of their institutions\' map collections. Both collections feature thousands of maps covering very similar areas, from the explorer\'s trails documented before Colorado became a state, through water and geographical features of the West, to ski runs of the 20th century. Denver Public Library began collecting western history in 1935, currently holding about 20,000 maps, with particularly strong Colorado collections on mining and the gold rush, railroads, transportation. As a City agency, the library holds a strong collection of Denver maps from its founding to the present, and is one of the top five public library map collections in the United States. History Colorado has been collecting since 1879, and its eclectic map collection includes many copies of well-documented maps, as well as some true gems.\ \ Craig Haggit began working directly with map collections at the University of Wyoming in the 1980s. Since obtaining his MLIS from the University of Kentucky in 1994, he has since administered the geospatial collections at MapQuest Publishing, Lancaster Public Library (PA), and now Denver Public Library\'s Special Collections and Digital Archives Dept.\ \ Shaun Boyd has been the Curator of Archives at History Colorado for 2 years, where she takes care of all the paper-based and/or information-intensive \"stuff\". Prior to that, she spent 19 years as an Archivist with the Douglas County Libraries in Castle Rock. She received her MA in History from Colorado State University, and a Master\'s of Library and Information Science from Emporia State University.
