Centre de documentation et d'étude sur la langue internationale
From Wikipedia, the free encyclopedia
The Centre de documentation et d'étude sur la langue internationale (CDELI = Center for documentation and study about the international language) in La Chaux-de-Fonds, Switzerland, was founded in 1967. It is the main branch of the city's library and contains more than 20,000 bibliographic units. Interlinguisticly neutral (thus "la langue internationale"), CDELI doesn't contain only Esperanto books and periodicals, but aims to preserve documents in and about all kind of constructed languages: it has the richest collections of materials about Volapük and Occidental, among others.
