The document discusses the Archivists' Toolkit (AT), a tool for archival data management. It summarizes the goals of the AT, which include supporting archival processing, promoting data standardization and efficiency. It then discusses how a collaboration is using the AT to create finding aids for over 200 hidden collections across 23 repositories as part of a Mellon-funded project. While the AT enables standardization and training, it is noted that the interface and digital objects could be improved. A future system called ArchivesSpace aims to combine the best of AT and Archon.
