ENIn nobility palaces of the Grand Duchy of Lithuania, among opulence and luxury, there were also spiritual assets – library, museum and archival collections. The Rare Books and Manuscripts Department of the Martynas Mažvydas National Library of Lithuania preserves books and documents from libraries and archives of estates of the Counts Kossakowskises in Vaitkuškis as well as the former Lyduokiai Estate. There are documents on purchasing publications and paying for them and administration and storage of funds from the 19th and 20th c. The most significant of them is a catalogue from the library of the Estate of the Vaitkuškis compiled by J.Wolikowska in 1898. This catalogue includes 9 860 storage units, books from 16 thematic sections and other lists of historical books and manuscripts. It mainly lists fiction and linguistic literature, as well as historical books and manuscripts, in French and Polish from the 19th c. It should be noted that in 1907 Mykolas Stanislovas Kossakowskis relocated 2 277 volumes from the Vaitkuškis library to the Lyduokiai Estate. The accurate number of books that were collected by the Kossakowskises and are now preserved at the National Library is hard to estimate, as not all of them have been catalogued yet. The manuscript heritage (1949 storage units) has been available to readers since 1985. Records of manuscripts and documents are integrated into National Library's electronic catalogue, and digital copies of documents compliment the web portal of the cultural heritage "epaveldas.lt".
