The Archives of the Archdiocese of New York preserves records relating to the history of the Roman Catholic Church in New York. The collections include the papers of the former ordinaries, auxiliary bishops, chancellors, vicars general, and the administrative records of various Archdiocesan agencies and programs. In addition, the Archives maintain a vast photograph collection. Also available in the collections of the Archives are parish annual reports, deceased diocesan priest files, parish commemorative books, and other parish and school history documents. The holdings encompass many formats of records such as maps, plans, paintings, sound recordings, video recordings, but it consists primarily of paper records. The main function of the Archives is to serve the administrative needs of the archdiocese, but also recognizes the historical value of the material it holds, and, as such, welcomes visitors to the repository.
