In 1898 the Berlin art dealer Paul Cassirer and his cousin Bruno Cassirer opened an avant-garde art salon with its own publishing house, the Bruno und Paul Cassirer Verlag (1898-1901). Together, within only three years, they acquainted the artistic and literary scene of their day with the latest European trends. In 1908, following the separation from Bruno Cassirer, Paul Cassirer founded the Paul Cassirer Verlag, in addition to the art gallery. Among the artists represented with significant texts and original graphic art were Max Liebermann, Max Slevogt, Ernst Barlach, Max Beckmann, Marc Chagall, Lovis Corinth, Heinrich Mann, Ernst Toller, Frank Wedekind, Georg LukAcs, Ernst Bloch, Ferdinand Lassalle and Else Lasker-SchA1/4ler. This bibliographic reconstruction presents for the very first time Paul Cassirer's entire programme along with all its series and periodicals. The exact bibliographical details of all books and portfolios rely on autopsy and also contain the bibliography of periodicals published by Paul Cassirer Verlag. A total of 886 titles are included - individual editions, variants of bindings of books as well as periodical issues and portfolios. The contents of the appendix include lists of publisher's catalogues, titles announced but never actually published, a chronological table and an index of names.
