I like Rhonda's list, but if it's to be for selling maps to libraries you might want to somewhat more restrictive in your definition. It's not too likely that you'll sell maps to places which don't have map libraries. But, on the other hand, I can't tell you how many times somebody has come up to me because they know I'm a geographer and MUST known something about where they can come by a map.

Always my first question is domestic or foreign? If it's domestic I send them to the local AAA office when they're members. If foreign, the AAA also sells city, regional, and national maps for lots of foreign places at not exhorbitant prices. If they're looking for more specialized maps, then there may be issues or point them at Google maps.

Some years ago I began visiting all the units of the National Park Sevice's system of which there were about 350 at the time (now it's about 420 or so). But the point is that the easiest way for me to map my way to drive to all of them in the Lower 48 was Google maps. And, I still have all the maps I printed out from Google maps, including the newly added ones in the Lower 48.

For one thing, random tourists don't normally think of the AAA. They also don't think of "Egad, Amazon!" as a source of maps.

So, I guess my question for Nat is: What is the actual long term purpose of your project? If it's to identify people who want to buy maps that's one thing. But, if you're trying to suck people into a map librarianship program, you'd probably be better off calling up the AAG and asking to buy their directory of geography graduate programs. This is simply because the likelihood of a strong map librarianship program is higher if there's a strong graduate program in geography.

Hope this helps.
