A new book collects hand-drawn maps of Manhattan submitted by both anonymous and notable New Yorkers: Becky Cooper’s Mapping Manhattan: A Love (and Sometimes Hate) Story in Maps by 75 New Yorkers.

It started with Manhattan in the summer of 2009 when Becky was still an undergraduate at Harvard University. Inspired by Italo Calvino’s Invisible Cities, as well as her own experience creating a map of New York’s public art, Becky walked the length of Broadway, distributing over a thousand letterpress-printed outlines of the borough to the widest variety of New Yorkers she could find.

The maps she got back have been posted online, and now there’s a book. Fascinating project. Brain Pickings and The New York Times Magazine have profiles (with image galleries). Via io9.
