[Rockhounds] USGS Folios

[Alan Goldstein]

I was handed about 40 to 50 USGS folios published between 1900 and 1929 - from Maine to California, North Dakota to Alabama. Unfortunately, none are undamaged. Most look good from the outside, but the inside has old water damage (minor to moderate on the upper edge) and mold spots along the same edge. These documents are about 3-feet tall and 2-feet wide. Most run 10 to 20 pages and all have maps inside. Any thoughts on what to do with them?
