United States and North America Historic Maps on CD - Explore our world through ancient maps. We offer a large number of map collections on CD which are sure to please map history buffs. Maps from the 14th century to the 19th century are included in the collections.
All maps are in MrSid format and the MrSID software is included on the CD. This format allows you to see the entire map on your computer screen or drill down to see the smallest details. The original maps are often quite large, as much as 36" long or larger and very detailed. With the MrSID software, you can manipulate the map to print the entire map in great detail or zoom into a portion of the map in full detail for viewing or printing.
