- I am positive that 1990 county boundaries are available in digital forma
- t from
- the USGS... you might also want to try "ftp spectrum.xerox.com". DLG files
- containing
- 1:2,000,000 scale maps of the US are available. The file called s0X.cb.XXX (X
- being some
- variable) should be county boundaries. I remember just looking at a set of them
- recently. The DLG format is pretty easy to convert to other formats you might
- want.
- I know that it requires a small amount of work to make them compatible with
- Arc/Info.
