David Cobb kindly sent this to me a few years ago. I recall deleting some columns of information and rearranging them slightly. Might be worthwhile checking with him to see if there is additional information that might be of use to others (I only wanted W,E,N,S coordinates for creating map cataloging records)

an Excel table with decimal coordinates for every US county. This 411MB

file is available for download at ftp://ftp.loc.gov/pub/gmdndl/. Please

save the file before opening it so to put less stress on our server. Any questions on the data will have to go back to Mary.

I am also going to work on converting this data to the format used in the MARC 034 field. If I succeed, is anyone else interested in this?
