The Ettinghausen-Oppenheimer Family Collection holds the papers of members of the Oppenheimer, Ettinghausen and related families. Much of the collection consists of a comprehensive assortment of birth and death certificates, last wills, military documents, school reports, marriage contracts, estate inventories for various family patriarchs, and other financial papers. Notable are two letters of protection (Schutzbriefe) for two family members.

The Oppenheimer and Sander Families Collection provide details of family members' lives via profuse personal correspondence, especially the letters of Emilie Oppenheimer and her daughter Betty. In addition to the many letters and postcards are a family tree, some poems and notes.

The Weinberg Oppenheimer Family Collection contains the papers of these families, with documentation primarily about Zacharias Oppenheimer, Leopold Oppenheimer, and Hermann and Bella (née Oppenheimer) Weinberg. The collection centers on the Weinberg family members' emigration to America as well as Leopold Oppenheimer and Hermann Weinberg's time in World War I. The collection includes many family and wartime photographs and a photo album of Leopold Oppenheimer's fraternity brothers, official documents and other papers used in the Weinbergs' emigration, family and emigration correspondence, documents related to the death of Zacharias Oppenheimer, newspaper clippings, a few diary entries, and other papers.

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.
