Hi Caroline, I'm not sure if this is exactly what you are looking for but here is a link to one of our USGS publications on the "History of the Topographic Mapping Branch " that you can download https://pubs.usgs.gov/circ/1341/pdf/circ_1341.pdf I have also provided a link to our USGS Historic Quadrangle Mapping Project, where we have scanned the majority of maps that we have made over time: http://historicalmaps.arcgis.com/usgs/ alternatively you may find historic maps here: https://ngmdb.usgs.gov/maps/TopoView/ This may provide you with the information that you are looking for. If you need something else please let me know.
