The Map Librarian pursues further exchange agreements with agencies both within the U.S. and abroad. Gifts provide a valuable supplement to the Map Room. However, the Map Librarian should evaluate all gifts prior to accepting them, in order to ensure that the items within the gift fit the needs of the Library and its patrons. The maps, books and other items selected support the areas of strength in the Arthur Lakes Library. All major geographic and subject areas are covered by basic cartographic materials.
Priority is given to materials based on geographic area and thematic content.
Though there are no chronological limitations, only current maps are actively collected. The thematic emphasis is on, but not limited to, geology, mining, energy resources, mineral resources, water resources, geophysics, engineering, and environmental sciences. Aerial photography is limited to Colorado. Worldwide topographic coverage is maintained. Only the latest version of each topographic sheet is kept.
