Hudson River Valley Heritage has a collection of historical atlases that cover several counties in the region, plus one atlas for New York to Troy. Several libraries loaned us their physical items for digitization. The majority of the imaging was outsourced. Our summer intern, Adrienne, spent a considerable amount of time creating metadata for maps from three 19th century atlases from Rockland, Sullivan, and Greene Counties. She also created metadata for maps from the 1891 Atlas of the Hudson River Valley from New York City to Troy. All of these maps can be browsed or searched through Hudson River Valley Heritage www.hrvh.org/exhibit/atlas.htm.
