Founded in 1969, the American Association for Ethiopian Jews (AAEJ) was instrumental in the international effort to promote recognition of the Beta Israel (known among non-Jewish Ethiopians as "Falashas") by Israeli authorities, and to assist Jewish emigration from Ethiopia to Israel. The extensive files of the AAEJ include case work files, research materials and Jewish artifacts collected in Ethiopia by AAEJ workers. In the wake of the successful evacuation of Ethiopian Jewry to Israel in 1993, the AAEJ decided to disband and voted to deposit its records at the American Jewish Historical Society. Included are correspondence, office files, photographs, slides, videotapes, audiocassettes and other materials which pertain to AAEJ's efforts to raise the consciousness of the American Jewish community about this unique Jewish subculture.

The records of Temple Beth El offer a valuable insight into a small town Southern Jewish community. The community members, composed mainly of German Jews devoted to the Reform movement, participated actively in charity work and mutual benefit societies, and maintained a close relationship with Jewish communities throughout the South. Temple Beth El was one of the first members of the Union of American Hebrew Congregations. Its history reflects the struggles a small town Jewish community experienced in maintaining their Jewish identity as well as the cooperation and acceptance of their non-Jewish neighbors. A significant part of the collection concerns the activities of women in the Helena Jewish community, who were a tight knit group that conducted extensive charity work. The Sisterhood took an active role as member of the Mississippi-Arkansas Federation of Temple Sisterhoods. The records also include minute books for the B'nai B'rith Esther Lodge. The collection contains correspondence, real estate deeds, financial ledgers, minute meetings, news clippings, a scrapbook, and photographs.
