Wykorzystanie zasobów internetowych do odtwarzania dawnych księgozbiorów na przykładzie prywatnej biblioteki Sebastiana Sierakowskiego, rektora Szkoły Głównej Koronnej w latach 1809-1814

Count Sebastian Alojzy Sierakowski (1743-1814) - architect, senator of Free Town Cracow and rector of Main Cracow School (Jagiellonian University) between 1809 and 1814 according to his last will gave the Jagiellonian Library his private library - about 1.000 volumes. Thanks to Ministry of Science and Higher Education Republic of Poland it is possible to reconstruct this collection according to Jerzy Samuel Bandtkie's lists. These lists are preserved in The Jagiellonian Library, but they are incomplet. Internet tools and resources are very helpful to recreate not only the Sierakowski's library, but also others old collections of books. Some of them are described in this paper.
