Connecticut History Online (CHO) is a digital collection of over 15,000 digital primary sources, together with associated interpretive and educational material. Now in its tenth year, CHO is embarking on a collaboration with the Encyclopedia of Connecticut History Online (ECHO) to serve the needs of scholars, K-12 and post-secondary teachers and students, genealogists, and the general public. This new initiative builds upon a very successful collaboration of libraries and museums focusing on digital capture of historical artifacts, including photographs, maps, broadsides, oral histories, manuscripts and oral histories.
The four current CHO partners, the Connecticut Historical Society, Connecticut State Library, Mystic Seaport, and the Thomas J. Dodd Research Center represent three major communities libraries, museums, and historical societies who preserve and make accessible historical collections within the state of Connecticut. Their combined assets include book and periodical volumes, manuscript materials, photographs and graphics, oral histories, maps, artifacts, and broadsides.
