Overview
HOLLIS for Archival Discovery (previously OASIS) is specifically designed for finding special collections and archival materials at 30 Harvard repositories.
These materials include primary sources like letters, photographs, film, 3D objects, and digital content. You can even save and return to your search results so you don’t lose the materials you’ve found.
Not all archival and special collections at Harvard have a finding aid, and are therefore not searchable in HOLLIS for Archival Discovery. To find other materials in special collections, use HOLLIS.
