Heinz Sarkowski's Bibliography of the Insel Verlag from 1899 to 1999 has been one of the standard works in German publishing and literary history since its first publication in 1970. Out of print for nearly 20 years and continually sought after by antiquarians, collectors, literary scholars, publishing historians, and librarians, the author and publisher are now presenting a revised and expanded edition for the anniversary.

Sarkowski's bibliography provides information in alphabetical order about all publications of the Verlag at its three locations - Leipzig, Wiesbaden, Frankfurt am Main - from 1899 to 1969, including special editions and press prints. It precisely documents editorial design, editors, translators, illustrators, book artists, editions, places of publication, page counts, bindings, and features.
