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 in a variety of formats such as letters, memos, photographs, film and video, three-dimensional objects, and digital content.
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.
