Hebrew incunabula amount to a rather modest, in terms of number, group of around 150 editions that were printed within the period from the late 60s of the 15th century to January 1, 1501 in Italy, Spain, Portugal and Turkey. Despite such a small number of Hebrew incunabula, the role they played in the history of the formation of European printing cannot be overlooked. Even less possible is to overestimate the importance of Hebrew incunabula for understanding Jewish spiritual life as it evolved in Europe during the Renaissance.

Russian depositories house 43 editions of Hebrew incunabula, in 113 copies and fragments. The latter are distributed as following: the Institute of Oriental Manuscripts of the Russian Academy of Sciences — 67 items stored; the Russian State Library — 38 items; the National Library of Russia — 7 items; the Jewish Religious Community of Saint Petersburg — 1 item. The majority of these books came in public depositories at the late 19th — first half of the 20th century from private collections of St. Petersburg collectors: Moses Friedland (1826—1899), Daniel Chwolson (1819—1911) and David Günzburg (1857—1910). This article looks into the circumstances of how exactly these incunabula were acquired by the depositories. For the first time there are analysed publications of Russian scholars that either include descriptions of Hebrew incunabula (inventories, catalogues, lists) or related to various aspects of Hebrew incunabula studies. The article presents the first annotated bibliography of all domestic publications that are in any way connected with Hebrew incunabula, covering the period from 1893 (the first publication) to the present. In private collections, there was paid special attention to the formation of incunabula collections. It was expressed in the allocation of incunabula as a separate group of books in printed catalogues and the publication of research works on incunabula studies, which belonged to the pen of collectors themselves and haven’t lost their scientific relevance today.
