Society of American Archivists Annual Conference, 2011 Session 503 Increasingly, archival repositories are collaborating to provide access to records across institutional and geographic boundaries. This session highlights three collaborative, consortial/regional programs that reach out to and partner with a range of institutions--public and private, large and small--to expose hidden collections. Panelists reflect on challenges, solutions and lessons learned within the context of collaboration, including cross-institutional processing projects, shared digital repositories and statewide digitization programs.
