Obtain map
- Go to USGS site http://store.usgs.gov/
- Click Advanced Search
- Enter map number in Old Material
- Click "Search"
- Click on the map image
- Save the PDF file
The maps are already georeferenced but you have to get it into a usable format.
For ArcMap you can use "TerraGo Publisher for ArcGIS" or Global Mapper ($350)
You could convert the PDF into a format (TIFF for example) readable by ArcMap and then georeference it, but that's a lot of work given the PDF is already georeferenced!
