The Lehigh Valley Historical Maps Consortium (LVHMC) is a group of local archivists, librarians, curators, and historians with an interest in historical maps who collaborate with the goal of establishing a collective inventory of maps related to the Lehigh Valley. Ultimately this inventory will provide a centralized resource for the discovery of maps which have been digitized for access over the internet, as well as for those physical maps which remain in map drawers in libraries, museums and historical societies across the Valley.
More information can be found at the Historical Maps of the Lehigh Valley Website.
