Amateur cartographers will spin cartwheels over this map collection, held at the Stephen S. Clark Library at the University of Michigan. Featuring 162 maps from the 17th century onward, the collection is completely public domain and browsable by all. Start anywhere - an 1849 mining map of Keweemaw Point in Michigan, or “A new and correct map of the world,” drawn by Herman Moll in 1732. The zoom function is a great aspect, as one might explore a map of the entire world, drawn perhaps in the 1600s, before narrowing in to the artist’s representation of the coast of Florida. These maps can provide hours of edifying fun.
