At the very least, the books may serve as a checklist and will give you an idea of how complex your retro-conversion/reclass project will be! Map index to topographic quadrangles of the United States, 1882-1940, by Riley Moore Moffat. c1985 (WAML Occasional Paper; no.10). A cartobibliography of seperately published U.S. Geological Survey special maps and river surveys, by Peter L. Stark. c1990 (WAML Occasional Paper; no.12).
