Fritz-Hüser-Institut, Literary research institute and archive in Bövinghausen, Dortmund, Germany.

The Fritz-Hüser-Institut für Literatur und Kultur der Arbeitswelt is a research institute with a special library, an archive and a picture archive, housed since 2007 on the grounds of the Zeche Zollern in Dortmund. Its library holds around 50,000 volumes, and the archive keeps 120 literary estates of writers, publicists and literary associations of the 19th to 21st centuries.

Fritz Hüser directed Dortmund's municipal library from 1945 and had collected worker literature since 1923. On his retirement in 1973 he donated his 10,000 books, pamphlets and newspaper articles to the city, which in return founded the Institut für deutsche und ausländische Arbeiterliteratur. Hüser led it unpaid until his death. Renamed in 1983 on his 75th birthday, it received its present name later and has occupied premises at the Zeche Zollern site since 2007.

The institute keeps the archives of the Dortmunder Gruppe 61 and the Werkkreis Literatur der Arbeitswelt, two German writers' associations of the industrial world. It also holds an archive on the workers' Esperanto movement and has shown an exhibition titled "To the workers of all countries one language!" in various European cities since 1993.

The institute has been housed on the grounds of the Zeche Zollern colliery since 2007, not near the Westfalenpark. It is open to the public for research and enquiries, and also supports school pupils' Facharbeiten. Check in advance which holdings you need, since the library and archive are consulted on request.

Among the 120 estates are papers of the Dortmunder Gruppe 61 and the Werkkreis Literatur der Arbeitswelt, plus manuscripts by Bertolt Brecht, Hermann Hesse and Stefan Zweig. The institute also keeps an archive of the workers' Esperanto movement and has shown an exhibition titled "To the workers of all countries, one language!" in various European cities since 1993.
