 After his death, his widow, Jean Erdman Campbell, felt that Pacifica would be able to carry Campbell's work into the future and, thus, would be the most appropriate home for his archives.She donated his 3,000-book library and archival collection to the Center for the Study of Depth Psychology, an independent non-profit organization housed at the Pacifica campus, which evolved into the Opus Archives and Research Center.The Joseph Campbell Archives and Library were installed in the school's Seminar Building and the home of the collection was formally dedicated in 1992.
