Leo Baeck Institute New York

The Yeshiva University Museum is a teaching museum and the cultural arm of Yeshiva University. Along with the American Jewish Historical Society, the American Sephardi Federation, the Leo Baeck Institute, New York and the YIVO Institute for Jewish Research, it is a member organization of the Center for Jewish History, a Smithsonian Institution affiliate located in New York’s Chelsea neighborhood.

The American Jewish Historical Society (AJHS) was founded in 1892 with the mission to foster awareness and appreciation of American Jewish history and to serve as a national scholarly resource for research through the collection, preservation and dissemination of materials relating to American Jewish history.

The American Sephardi Federation, a founding member of the Center for Jewish History, is a non-profit Jewish organization that strengthens and organizes the religious and cultural activities of Sephardic Jews, preserves Sephardic heritage, tradition and culture in the United States, and assists in the publication of books and literature dealing with the Sephardic culture and tradition. The federation also works to further awareness of the former existence of large Jewish communities in the Muslim and Arab world.

The Center for Jewish History is a partnership of five Jewish history, scholarship, and art organizations in New York City: American Jewish Historical Society, American Sephardi Federation, Leo Baeck Institute New York, Yeshiva University Museum, and YIVO Institute for Jewish Research. Together, housed in one location, the partners have separate governing bodies and finances, but collocate resources. The partners' collections make up the biggest repository of Jewish history in the United States. The Center for Jewish History also serves as a centralized place of scholarly research, events, exhibitions, and performances. Located within the Center are the Lillian Goldman Reading Room, Ackman & Ziff Family Genealogy Institute and a Collection Management & Conservation Wing. The Center for Jewish History is also an affiliate of the Smithsonian Institution.

YIVO (Yiddish: ייִוואָ, [jiˈvɔ]), established in 1925 in Wilno in the Second Polish Republic (now Vilnius, Lithuania) as the Yidisher Visnshaftlekher Institut (Yiddish: ייִדישער װיסנשאַפֿטלעכער אינסטיטוט, pronounced [ˈjidiʃɛr ˈvisn.ʃaftlɛχɛr instiˈtut], Yiddish Scientific Institute), is an organization that preserves, studies, and teaches the cultural history of Jewish life throughout Eastern Europe, Germany, and Russia as well as orthography, lexicography, and other studies related to Yiddish. (The word yidisher means both "Yiddish" and "Jewish.") The English name of the organization was changed to the Institute for Jewish Research after its relocation to New York City, but it is still known mainly by its Yiddish acronym. YIVO is now a partner of the Center for Jewish History. Formerly, they had linguists whose main occupation was deciding on grammar rules and new words, and during this time they were seen in the secular world to serve as the recognized language regulator of the Yiddish language. However, YIVO no longer serves this purpose. Nevertheless, the YIVO system is still commonly taught in universities and known as klal shprakh (spelled in Yiddish:כּלל־שפּראַך) and sometimes "YIVO Yiddish" (spelled in Yiddish:ייִוואָ־ייִדיש).

The International Juridical Association (IJA; 1931–1942) was an association of socially minded American lawyers, established by Carol Weiss King and considered by the U.S. federal government (in the form of the U.S. House Un-American Activities Committee or HUAC) as "another early (communist) front for lawyers. The principal concern about the IJA (and, as of 1942, its successor group, the National Lawyers Guild or NLG) was that it "constituted itself an agent of a foreign principal hostile to the interests of the United States."
