Difficult talks with the Ukrainian side began in 1992. About 70% of the pre-war collections of the Ossolineum remained in Lviv after the war. Voices were heard demanding the return of the pre-war collections of the Ossolineum. In 1993, the deputy directors of the Ossolineum Library and the Stefanyk Library in Lviv signed a Memorandum of Understanding on cooperation between the two libraries, but it was not until the establishment of the Polish-Ukrainian Intergovernmental Commission for the Protection and Restitution of Cultural Property Lost and Illegally Displaced During World War II that the impasse was resolved. During its first meeting (13-16 May 1997 in Lviv), a team of experts on the Ossolineum was appointed. The Director of the National Ossolinski Institute, Dr Adolf Juzwenko, and the Director of the Vasyl Stefanyk Scientific Library of the National Academy of Sciences of Ukraine, Professor Myroslav Romaniuk, became co-chairs of the team.
