Garth et al,

 

A couple of comments regarding LOC Sanford Maps.

 

  1. The index page for each Volume has a change history shown.  If you look at that page you can see the original (copyright) date as well as the history of the dates that changes were made.
  2. All of the digitized LOC maps are in color and are available for free download in several file formats and resolutions from the LOC.

Bill and friends,

 

Some cautions with the Sanborn maps are in order.

 

Some of the colorful paper originals had updates pasted in over the years, so a book issued with a particular date might actually contain later information. Of course, this is hard to see on a digitized version, and IIRC, they paste-ins were not dated.
