The Austrian National Library's Department of Planned Languages is home to the world’s largest specialist library for interlinguistics, documenting around 500 planned languages. In addition to Esperanto, the most important planned language in the world today, these also include Volapük, Ido, Interlingua and many others. In the department’s reading room you can discover a whole host of books and magazines in planned languages, multifaceted archives and impressive musical recordings and films.

Ever since it was founded in 1927, the Esperanto Museum at the Austrian National Library has held an extensive library, which was given the name “Department of Planned Languages” in 1990. Planned languages – languages that are deliberately created according to specific criteria – are the subject of the scientific discipline that has been known since the start of the 20th century as interlinguistics.
Subdivided by document type, the library holds about 40,000 flyers, 40,000 printed volumes, 25,000 newspaper articles, 22,000 photographs, 20,000 handwritten texts and manuscripts, 4100 journals, 3500 museum artefacts, 1600 posters and 1200 sound recordings.
