The three major reference works compiled by the UIA are the Yearbook of International Organizations, providing the authoritative overview of international associations; the International Congress Calendar, offering information on around 550,000 meetings and events in the world of international associations; and the Encyclopedia of World Problems and Human Potential, a unique research platform interlinking world problems, action strategies and human values. The Encyclopedia is available as a free public resource, and there are several different options to access the data assembled in the Yearbook and the Congress Calendar.

The International Meetings Statistics Report and the Survey on International Meeting Issues are indispensable for a thorough analysis of the meetings and topical discussions of the international association community. Customized data extractions and statistical reports that highlight tailored data needs on all aspects and activities of international associations are also available upon request.

Past publications are freely available for research purposes, including a complete list of all UIA publications since our foundation in 1907. There is open access to a large number of UIA’s journal, and the entire UIA archives may be consulted by appointment.
