Identifying Archival Collections
Archives and special collections are by their nature difficult to identify with a central database. Small special collections are frequently missed and large collections have material that haven't even been described yet.
It is important to go beyond these indexes and contact libraries and archives that might have relevant resources to speak with the local experts.
Special collections outside of the United States and England often lack central repositories of bibliographic information, so one often needs to approach the collections directly. A lists of many archives in countries around the world is available here and the International Directory of National Archives is available here.
Provides centralized access for searching and retrieval of archival records and finding aids, including finding aids indexed centrally at RLG and others located on servers around the world and records in RLG's AMC (Archival and Mixed Collections) file. AMC provides researchers with timely and comprehensive access to brief, high-level information for nearly half a million collections of manuscripts and archives.
Database containing the records of all material cataloged by OCLC libraries, including hundreds in the United States and some major libraries in other countries. Manuscript collections that are cataloged by these libraries will appear in Worldcat.
