The Newark (N.J.) Archives Project is a comprehensive online source of information about primary materials for all periods and all aspects of Newark history, from Colonial times to the 21st Century. Co-sponsored by the Newark History Society and Rutgers University-Newark, the Project cooperates closely with the staffs of the many libraries and archives it surveys (including Seton Hall). The evaluators are creating detailed descriptions of Newark-related material, both catalogued and un-catalogued, located in repositories in Newark, in New Jersey and New York, and ultimately throughout the United States. This team surveys papers of individuals and families; records of government agencies, organizations, and businesses; photographs and film; audio collections; and more. Their database of collection descriptions is constantly growing as more resources are uncovered. Searching can be conducted via their detailed descriptions of hundreds of archival collections by keyword, by name, by subject, and by time-period.
