PSB meaning in News & Entertainment ?

Polski Słownik Biograficzny (PSB; Polish Biographical Dictionary) is a Polish-language biographical dictionary, comprising an alphabetically arranged compilation of authoritative biographies of some 25,000 notable Poles and of foreigners who have been active in Poland – famous as well as less-well-known persons – from Popiel, Piast Kołodziej, and Mieszko I, at the dawn of Polish history, to persons who died in the year 2000.

The Dictionary, published incrementally since 1935, is a work in progress. It currently covers entries from A to S and its completion is expected about 2030.

The PSB is, by its own assessment, "at present... one of the world's leading biographical publications." Outside Poland, it is available at the British Library, the Library of Congress, the Vatican Library, the Hoover Institution on War, Revolution and Peace, the University of California at Berkeley, Stanford University, the Getty Museum, and many other national and major research libraries.
