Real Estate Atlases - State Library of Massachusetts
"As part of a grant-funded project, the State Library is digitizing the Massachusetts Real Estate Atlases in its collection. These atlases provide information about property boundaries, plot size, ownership, building shapes, and materials and are heavily used by genealogists, architectural consultants, people researching the history of their homes, and others. This project is supported by the Institute of Museum and Library Services under the provisions of the Library Services and Technology Act as administered by the Commonwealth of Massachusetts Board of Library Commissioners."
