Archon is an open source, Web-based archive management system for archivists and manuscript curators that automatically publishes archival descriptive information and digital archival objects.
Archon users do not need to encode a finding aid, input a catalog record, or program a stylesheet. Archon operates through scripts that automatically make data elements in the system searchable and browsable on a repository website. Information can be input or edited using simple web forms. Archon automatically uploads the information, publishes the website, and generates EAD and MARC records.
