The Gruen-Gruenebaum Family Collection documents the experiences of family members during the 1930s and 1940s as well as provides some information on the community of Altenkirchen, Germany. The bulk of the collection consists of personal correspondence sent to Walter Gruen (previously Grünebaum). Other material consists of drafts of essays on genealogy and official documents of family members.

The Wolf-Oppenheimer Collection provides details on the lives, both personal and professional of more than three generations of members of the related Wolf and Oppenheimer families. Most prominently represented among the collection's papers are Hermann and Irene (née Oppenheimer) Wolf and their daughter Marlies (née Wolf) and Eugene Plotnik, but the papers relate to many other family members as well. The collection includes personal papers, official and educational documents, family correspondence, photographs, family trees, articles as well as personal family writing, and newspaper clippings.
