More on Patents and Cartographic Inventions

Earlier this year I mentioned the publication of Mark Monmonier’s latest book, Patents and Cartographic Inventions. This week at All Over the Map, Betsy Mason does a bit more than mention the book, with a closer look at some of the more unusual patents from Monmonier’s book: an early voice navigation system, a map folding method, and a rural address system. (None of which caught on, of course.)
