This supplement to the Deutsches Theater-Lexikon , amplifies and extends Volumes I-VII (A-Z), which appeared between 1953 and 2011. Articles have been re-edited with an emphasis on the 20th century, and personalities who were not previously included have been newly added. The lexicon contains bio-bibliographic information about playwrights, composers, theatrical directors, producers, actors, singers, set designers, and costume designers.
