The main tools for identifying processed archival collections beyond NYU include WorldCat, ArchiveGrid, and NUCMC, which are described below. Researchers are encouraged to search all three, even though there will likely be some overlap in search results, to ensure that they have not overlooked relevant collections.
Archive Grid - Database with collection level descriptions of archival holdings and search capability within finding aids contributed by thousands of libraries, museums, and archives.
National Union Catalog of Manuscript Collections (NUCMC) - A gateway for searching OCLC WorldCat (Manuscript materials) provided by the Library of Congress. Contains nearly 1.5 million catalog records describing archival and manuscript collections and individual manuscripts in public, college and university, and special libraries located throughout North America and around the world.
WorldCat - Contains records for more than 1 billion items in more than 10,000 libraries worldwide. Use the advanced search feature to limit results to archival materials.
N.B. All repositories have collections that have not yet been arranged and described. Unprocessed collections will not turn up in searches of these databases and may not appear in a library's own catalog. Contact repositories directly to inquire about the availability of unprocessed archival collections.
