Зв’язки українських науковців із Національним Закладом ім. Оссолінських у Львові

This article is devoted to the cooperation between Ukrainian scientists and cultural activists and the Ossolineum in Lviv (1827–1939). At the very beginning of its existence this institution collected many documents concerning the history of Ukraine and the Ukrainians. The rich resources of the archives and collection were used not only by the western Ukrainian members of the Scientific Society named by Szewczenko but also scientists from Dnieper Ukraine
