When I was looking at those maps in dealers’ shops or catalogs, I often saw other maps that I thought were fun and interesting. I didn’t quite understand them all—unusual maps, strange maps of different kinds. The kind of maps that dealers refer to as “cartographic curiosities” (which basically means, “This doesn’t fit into one of my pigeon-holes…”). These were kind of fun and interesting, and they were inexpensive so, on a lark, I would buy them when I saw them and then I would kind of try to figure out what they were.
More than 500 maps have just been added to the P. J. Mode Collection of Persuasive Cartography at the Cornell University Library. That’s almost double the number they began with. Via email, P. J. Mode also says that “Cornell has implemented a much-improved image browser with a very robust search function. I hope there are some things that you’ll find new and interesting!”
