Introduction to the Archivists Toolkit

The Archivists’ Toolkit™, or the AT, is the first open source archival data management system to provide broad, integrated support for the management of archives. It is intended for a wide range of archival repositories. The main goals of the AT are to support archival processing and production of access instruments, promote data standardization, promote efficiency, and lower training costs. Currently, the application supports accessioning and describing archival materials; establishing names and subjects associated with archival materials, including the names of donors; managing locations for the materials; and exporting EAD finding aids, MARCXML records, and METS, MODS and Dublin Core records. Future functionality will be built to support repository user/resource use information, appraisal for archival materials, expressing and managing rights information, and interoperability with user authentication systems. The AT project is a collaboration of the University of California San Diego Libraries, the New York University Libraries and the Five Colleges, Inc. Libraries, and is generously funded by The Andrew W. Mellon Foundation.

Please note that the AT is superseded by ArchivesSpace ( and AT support ended September 1, 2013. This website ( will be available for the next few months as the transition is made to ArchivesSpace. As much documentation as possible, along with the latest source code is also posted on the AT GitHub site:
