The Esperanto Museum of theAustrian National Library is one of the oldest language museums in the world and one of the major institutions of its kind. Since its founding in 1927, the museum has housed an extensive library, which was designated the Department of Planned Languages in 1990. Over 90 years of continuous collecting has resulted in what is today the world's largest specialized library forEsperanto,planned languages, andinterlinguistics.
The Esperanto Museum was founded in 1927 by Hugo Steiner as an association and integrated into the National Library in 1928 under the name International Esperanto Museum. According to Hugo Steiner, the idea to establish an Esperanto Museum arose during the 19thWorld Esperanto Congress inDanzig in 1927 and traces back to Felix Zamenhof, a brother ofLudwik Zamenhof. After the annexation of Austria the collection was closed by the Gestapo in 1938. It was reopened in 1947 in the St. Michael’s Wing of theHofburg. In 2005, the Esperanto Museum and the Department of Planned Languages moved toPalais Mollard-Clary at Vienna's Herrengasse 9.
With more than 150,000 media items the Department of Planned Languages is the world's largest specialized library for interlinguistics and documents around 500 different planned languages (and projects), includingVolapük,Ido,Interlingue (Occidental), andInterlingua. The collection preserves and provides approximately 45,000 volumes, 30,000 letters and manuscripts, 22,000 photographs, 4,500 different periodical titles, 3,500 museum objects, 1,800 posters, 1,700 audiovisual media, and more than 80 archives from personal and institutional provenance, including holdings fromMarjorie Boulton,Kálmán Kalocsay, Juan Régulo Pérez,Manuel de Seabra,Eugen Wüster, Ludwik Zamenhof, and the archive of theUniversal Esperanto Association. The items can be searched online in the QuickSearch and ÖNB Digital catalogues, with more than 45,000 catalogue entries providing direct links to digital copies.

The multimedia permanent exhibition explores the eventful history of Esperanto, from the publication of theUnua Libro in 1887, through its rapid spread beforeWorld War I, and persecutions underNational Socialism, to its use today. Esperanto has continually advanced in the field of literature, as demonstrated, among other things, by original Esperanto works byGyula Baghy,William Auld, andSpomenka Štimec, which have been translated into several other languages. Interactive multimedia stations also present other planned languages, such as the mysticalLingua Ignota byHildegard von Bingen, the musical languageSolresol, and theKlingon language from the television seriesStar Trek.
