ENEustachy Tyszkiewicz is known in historiography as a historian, archaeologist, and the founder of the Vilnius Museum of Antiquities. However, he was also a collector: having collected books his entire life, he formed a private library, whose origin, nature and fate have not been sufficiently explored. In this paper, while referring to the surviving library catalogues and lists, book markings (provenances, marginalia), correspondence and bibliographical information, the authors try to reconstruct the world of Tyszkiewicz's books and establish his links with publishers and other contemporaries. The collection of the Lahoysk manor, where Tyszkiewicz was born, and the circumstances of the inclusion of his private library in the Vilnius Museum of Antiquities and its later dissolving, are discussed. Tyszkiewicz used his skills of a collector and bibliographer, which he had acquired while collecting historical and archaeological material at the St. Petersburg Imperial Library in 1832-1835, in organising the library of the Vilnius Museum of Antiquities, and in 1865-1871, while managing the collections of Tyszkiewicz's majorat in Biržai, he compiled a catalogue of the library of the Astravas manor. A question about the role of Tyszkiewicz in rescuing the decaying objects with cultural value from the closed monasteries, and popularising the history and traditions of the historical lands of the Grand Duchy of Lithuania, is also raised.
