Priceless medieval manuscript "Sermones scripti", which was considered as destroyed was passed on November 17 to the National Library in Warsaw. The ceremony was attended by: Minister of Culture and National Heritage prof. Małgorzata Omilanowska, Director of the National Library Tomasz Makowski and representatives of the German side: prof. Thomas Bürger, Director of the Saxon National Library  - Dresden State and University Library and Rolf Nikel, Ambassador of the Federal Republic of Germany in Poland.

The efforts of the Ministry of Culture to recover the manuscript lasted for several months. The manuscript has been identified in the electronic catalog of the University Library in Dresden. After that, The Ministry of Culture sent  an expert to the library to verify the identity of the manuscript. Expert confirmed that this is a lost document from the pre-war National Library.

Since first half of the fifteenth century manuscript had belonged to the vicars library  at the collegiate in Wiślica and was kept there until the early nineteenth century. Then went to the Library of the Warsaw Society of Friends of Science, from where after the collapse of the November Uprising was looted by the tsarist authorities together with other library collections and included in the Tsar's Public Library.

After the Polish-Soviet war, under the Treaty of Riga of 1921, nearly all exported to St. Petersburg manuscripts were returned to Poland, including "Sermones scripti". After returning went to the National Library. After the Warsaw Uprising in October 1944, manuscripts collection of the National Library had been almost completely burned and it was believed that among them was also "Sermons scripti". It turned out, however, that the manuscript was moved along with surviving collections of the National Library to Moscow. In 1958 manuscript was mistakenly revindicated from Moscow to the library in Dresden (SLUB) as it was considered to be a part of the Dresden collection confiscated in 1946  by the Soviet authorities.
