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 . I actually had a script that automatically downloaded from there and "scraped" the HTML -- but sometime since I wrote the script, the HTML structure on the page changed and it broke. (I kind of thought that was unlikely since that HTML page itself was machine generated -- but I guess they changed the software that generated it. Certainly I knew that scraping HTML was a bad thing to rely on... which is why I hope LC provides this in some format less likely to change?)
