The Library has several copiers on the 2nd level. The Library does NOT have an engineering, or oversized, copier. In order to copy a large map, you can do it in pieces and then put them together. Or you may check out the map, and take it to a local copy store that has an engineering copier. If you wish to purchase a general road map of a particular state or of the Denver region, try a local bookstore.
Some larger stores have maps of foreign countries too.
There are many full-time map stores in the Denver Region. Acquiring maps of foreign countries can be difficult. There are 2 major map dealers in the United States that specialize in foreign maps, MapLink and Omni Resources. The office hours of the Map Room are Monday through Friday, 8am to 5pm. The Map Room itself, and the Map Collection are open all hours the Library is open.
