British map dealer Philip Burden — his company is Clive A. Burden Ltd., named for his late father — is in the U.S. on a book tour; the second volume of his massive (and expensive!) bibliographic reference, The Mapping of North America, is now out (volume one was published in 1996). The Raleigh News and Observer has the story; he’s in town to give a talk tomorrow.
