ArchivesSpace is an open-source, archives information management web application designed for managing descriptive information about archives, manuscripts, and digital objects.

The ArchivesSpace application was first released in September 2013, and it is sustained by an active member community of over 400 organizations. Community collaboration and member contributions support and guide all facets of ArchivesSpace—development, code review, migration support, technical and user documentation—and are key to the advancement of both the ArchivesSpace application and community.

ArchivesSpace's organizational home is LYRASIS.
