The museum Bulletin was published from 1903-2012. These are all available via JSTOR (please note that from 1903-1938, the publication was called the Pennyslvania Museum of Art Bulletin. The name was changed to reflect the museum's name change). Hard copies from 1903 through 2008 are available in the library reading room.
Alongside the Annual Report and Bulletin, the Board of Trustee (and related committees) minutes are another good resource for learning about staffing changes, major acquisitions, as well as departmental shifts. These records are a part of our archival collection. Please consult the finding aid and contact the archives if you are interested in accessing these records.
