The reference work , '' Polsko-angielsko-niemiecki Glosariusz regionalny Województwa Opolskiego '' ( The Polish-English-German Glossary of the Regional Terminology of the Province of Opole ) , written by Tomasz Kamusella was published in 2004 in Opole by the publishing house , Oficyna Piastowska ( ) . The book ’s run of 2000 copies was destroyed by Roman Hlawacz , the owner of the Oficyna Piastowska , on the order of the Self-Governmental Regional Authority ( '' Urząd Marszałkowski '' ) of the Province of Opole , Poland , transmitted to him orally by Ewa Rurynkiewicz , a Deputy President of the Province of Opole . The step was taken , because in the overview of the history of the region the reference , apart from giving the Polish and Soviet view according to which the new German-Polish border was recognized in 1945 at the Potsdam Conference , also included the view propounded by the Western Bloc and West Germany , namely , that the border was finally and fully recognized in light of international law only when the German-Polish Border Treaty ( 1990 ) was ratified in 1992 . Although the glossary was positively reviewed for publication ( including the information on the status of the German-Polish frontier ) by the Opole sociologist , Danuta Berlińska and the Opole politician , Danuta Jazłowiecka , at present a MEP ; Deputy President Ryszard Galla publicly appealed for burning all the copies of the Glossary
