restricted access Julius Hanauer: Bio-Bibliographical Traces of a German Special Librarian, Esperantist, and Documentalist

The German librarian Julius Hanauer, primarily known for his support of decimal classification in the 1920s, was an important link between Germany and the international bibliographic movement and documentation network in the first third of the twentieth century. Working in the early twentieth century at the Institut International de Bibliographie in Brussels, Hanauer had regular contact with members of the documentation community, such as Henri La Fontaine and Paul Otlet, and others outside Belgium, such as Wilhelm Ostwald. Tracing the facets of Hanauer’s activities and connections as an information pioneer mirrored the contemporary world of internationalism and documentation.
