On my recent visit to the Rocky Mountain Philatelic Library (RMPL) I got a chance to see RMPL’s map room which includes maps from the U.S. and the world. The collection is maintained by Steve Schweighofer, a library volunteer who contributed many of the maps himself. The RMPL has been able to acquire map cases that are designed to store large maps flat. Maps can be a valuable resource for the postal historian. The RMPL map collection includes highway maps, topographical maps, railroad maps, and others. Steve continues to work to organize the maps in the most useful manner possible. Thanks for taking time to show me this great resource Steve.
