I went through a process similar to what you describe sometime back for a tool I made (i.e. I could find no easily downloadable info). You can download something that will be easier to parse from http://calculate.alptown.com/gac.js It's probably not 100% accurate as I haven't downloaded for quite awhile. But catalogers have me correct errors they discover and there are about 800 unique visitors per day so I assume they notice most things. It would be nice if this kind of data could be provided in a straightforward format. kyle On Wed, Jun 22, 2011 at 2:44 PM, Jonathan Rochkind <[log in to unmask]> wrote: > Can anyone remind me if there's a machine readable copy of the MARC > geographic codes available at any persistent URL? > > They're in HTML at http://www.loc.gov/marc/**geoareas/gacs_code.html<http://www.loc.gov/marc/geoareas/gacs_code.html>.
