The annual World Congress of Esperanto (Universala Kongreso), which attracts 2000-5000 people to a different city each year, is held under the direction of UEA. UEA also publishes books and has the largest mail-order Esperanto bookstore in the world (with over 4000 books, CDs, and other items), maintains an information center and a significant Esperanto library. UEA also maintains a network of representatives from around the world, who are available to provide information about their geographical area or professional field.
TEJO, the World Esperanto Youth Organization, is the youth section of the UEA. Similar to the Universala Kongreso of UEA, TEJO organizes an International Youth Congress of Esperanto (Internacia Junulara Kongreso) each year in a different location. The IJK is a week-long event of concerts, presentations, excursions, and general having fun that attracts hundreds of young people from all over the world.
In addition to the UN and UNESCO, UEA also has consultative relations with UNICEF and the Council of Europe and a general working relationship with the Organization of American States. UEA works in an official capacity with the International Organization for Standardization (ISO). UEA is active in public information in the European Union and as necessary at other interstate and international organizations and conferences. UEA is a member of the European Language Council, a common forum of universities and language associations for the awareness of languages and cultures in and outside of the European Union.
