About CED – CED

Centre for Research and Documentation on World Language Problems (CED)

The Centre for Research and Documentation on the World Language Problem (CED) was established in 1952 to advance scholarly research on Esperanto “and its multifaceted applications in all spheres of life”; to ensure the compilation and editing of reliable documentation on Esperanto; and to support efforts to present the facts about Esperanto to international organisations, scholarly and specialist associations, and wider publics. Originally, then, CED was conceived as a specialist organisation in support of the worldwide Esperanto movement under the umbrella of the Universal Esperanto Association (UEA).

Gradually, CED’s activities and goals expanded. It also adapted its name to avoid the possible misperception that there is only one “language problem” in the world; it is now called the Centre for Research and Documentation on World Language Problems. Although still formally linked to UEA, its work has long responded to the priorities and initiatives of researchers in the fields of interlinguistics and linguistic justice, rather than to the needs of UEA. Esperanto remains CED’s main working language; for various purposes related to research and documentation, CED has long also used English, French and other languages.
