----------------------------Original message---------------------------- Hello Maps-L readers! For quite some time I have been an avid collector of maps dealing with urban mass transportation networks--those systems of public transportation in cities which include commuter rail lines, subways, trolleys/trams/light rail, and buses/trolleybuses. These range, of course, from poster-size, colorful schematic diagrams of spider web-like rapid transit lines to the common pocket-sized bus schedule with its accompanying route map. I would be interested to know of any libraries or collections out there which "specialize" in this type of map, and would enjoy "meeting" others who share in my interest. Besides the transit authorities themselves, I would also be interested to know in other sources for such maps. Thank you! Ryan S. Park respond to: [log in to unmask]
