Maps are in MrSid format, which 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 quite 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. You could even bring the images to a local print shop to have the maps reprinted in their full size. The software is included on the CD. This is a must have collection for any historic map or American Indian history buff!

To use this software, you must install the free ExpressView MrSid software which is included on the CD. This is a 30 second process and will allow you to view and manipulate/print all the maps in this CD collection in full detail. There is a version for Windows platforms and full installation instructions are included on the CD.
