The Carpenter Collection is dedicated to nineteenth- and twentieth-century records of land ownership in the U.S.A. It is divided into several sections by format: ca. 1,500 atlases [CCA], mostly county atlases; 28 books [CCB], and ca. 300 separate maps [CCM]. While catalogued and available for consultation at OML, digital access is restricted. Instead, the collection is accessible through Historic Map Works.
Charles and Dalinda Carpenter were long-time residents of Portland, Maine before relocating to the Dominican Republic where their philanthropic efforts were focused in building and equipping primary schools. Having assembled his very large collection of maps, atlases, and gazetteers, Charles Carpenter used them as the foundation for his company, Historic Map Works.
