John,

The Mid-Continent Public Library (Kansas City area - Missouri side) offers access to the complete collection of black and white Sanborn maps for the U.S.

If you are not a resident of the district, you must apply in person for a card and pay a yearly fee based on their FAQ. They also limit card issuance to U.S. addresses. I do not know if they have special rules for military members out of country.

Their web site is and you could contact someone at the library system to get more information.
