Edgar Allen Beem’s essay in the May/June issue of Humanities serves as a good introduction to the Osher Map Library, a major map collection housed at the University of Southern Maine in Portland. The Osher Map Library turns up a lot in my online cartographic perambulations; it’s good to know the history and origins of the place and the people working there (e.g. faculty scholar Matthew Edney, who also directs the History of Cartography project, and director Ian Fowler, who joined in 2014).
