There are 10 volumes in this series. The ad for these books describes these volumes as "Nearly 50,000 locations comprise the 10-Volume set, all sites pinpointed on large, easy to read state highway maps..." Each state map contains numbered dots which corresponds to a list identifying a ghost town, historical site, or potential treasure location. It then becomes the responsibility of the reader to research the site(s) of interest and determine whether the location is an actual viable site.
