The Society for Handicraft and Agricultural Work among the Jews of Russia, known by its Russian acronym, "ORT," was founded in St. Petersburg, in the Russian Empire, in 1880. Its aim was the promotion and development of skilled trades and agriculture among Jews, especially through support of vocational and agricultural training. At first operating only as a provisional committee, it received legal recognition in Russia in 1906, and subsequently established local divisions in various cities within Russia and, after the First World War, in Poland, Lithuania, and other countries. An ORT committee was formed in Vilna in February 1919; the ORT Society in Vilna helped found an international umbrella organization, the World ORT Union, in 1921, with headquarters in Berlin (until 1933) and, later, Paris. The collection comprises records of the ORT Society in Vilna that, despite their fragmentary nature, broadly reflect the society's activities from its beginnings until its dissolution by the authorities in Soviet-occupied Lithuania, in 1940. The collection contains administrative records, such as bylaws, minutes, reports, membership records, and financial records; outgoing and incoming correspondence, with correspondents including the ORT Central Committee in Poland, Warsaw (founded 1923); records pertaining to the administration of the society's vocational programs, including its Crafts School, which trained Jewish youth as artisans in the fields of carpentry and locksmithing, and various professional advancement courses for adults, in fields such as electrical installation and tailoring (cutting); records concerning activities related to agriculture in the period 1920 to 1923, apparently reflecting the work of an ORT regional committee based in Vilna (loan applications and questionnaires about Jewish families working on farms, in most cases pertaining to localities in the western part of present-day Belarus); and a few items documenting a credit cooperative society founded by the Vilna ORT Society.

The Jewish Vocational (Technical) School of ORT in Vilna, known as the Technicum, opened in Vilna (Wilno, Poland; today, Vilnius, Lithuania) in 1921 and remained in existence until 1940. It trained Jewish young people in the fields of mechanics and electrical engineering over a three-year course of study. The Technicum was subsidized by the ORT Central Committee (Warsaw), the Vilna Jewish Community Council, and the Vilna municipality. The school was equipped with laboratories and workshops, as well as a technical library, and published a series of its own Yiddish-language textbooks for use by students.

The collection comprises a portion of the records of the Jewish community of Ostrów Wielkopolski, today in west-central Poland, in the Greater Poland Voivodeship. The region was annexed by Prussia in 1793, in the Second Partition of Poland; in German the town was known as Ostrowo. The records date mainly from 1834 to 1919, with a few materials from as early as 1822. During this period the town was part of the Posen (Poznań) region of Prussia and, after 1871, of the German Empire; in 1919, it was incorporated into the Second Republic of Poland. The community numbered nearly 2,000 members in the late 19th century and declined steadily thereafter due to migration of members to larger German cities or overseas; only a small Jewish community remained during the interwar period. The records are mainly those of the Jewish communal administration, or council; a small amount of material pertains to several community voluntary organizations. Included are financial records such as budgets, balance sheets, and tax lists; communal minutes and decisions throughout the period; correspondence with the government, and, to a lesser extent, with Jewish organizations and other Jewish communities; records pertaining to community members' naturalizations, marriages, births, and synagogue seat contracts; petitions from individual community members, especially pertaining to charitable aid in the mid to late 19th century; records pertaining to communal educational and religious institutions; records on the hiring and employment of community rabbis,cantors, and other personnel, including application materials from candidates not hired; property records and mortgages; documentation of construction and renovation of communal buildings; records related to court cases, bequests, and estate and guardianship matters; and ephemera such as meeting notices and announcement fliers, as well as scattered clippings.

Young Judaea is the oldest Zionist youth organization in the United States, established as a national organization in 1909 by the Federation of American Zionists.

Young Judaea has remained non-partisan and non-denominational, embracing and recruiting Jewish youth from all backgrounds.
