Manhattan’s Map Room

The New York Post has an item on the Map Room (no relation) of the Borough of Manhattan’s Topographic Bureau, which is responsible for the official maps of New York County (largely defunct and contiguous with Manhattan) since 1748; last week a call was put out for help in preserving roughly 800 of the 4,000 maps — they’re starting to crumble.
