In performing its tasks and functions, ECOSOC has established a number of subsidiary organs. Apart from Functional Commissions and Regional Economic Commissions, there are Permanent Committees and Expert Committees for important tasks, as well as Ad-Hoc Committees.
There has been a considerable increase of such subsidiary organs of ECOSOC and other additional intergovernmental bodies in the economic, social, humanitarian and economic fields.
There are special committees for Non-Governmental Organizations, for Negotiations with Inter-governmental Agencies, for the Transport of Dangerous Goods, on the Globally Harmonized System of Classification and Labelling Chemicals etc.
A web portal to the Special Committees of the Economic and Social Council is posted at the official web site of ECOSOC, section Subsidiary Bodies.
Full text documents can be accessed through the web sites of the subsidiary bodies.
The subsidiary bodies submit an annual report to ECOSOC in the documentary series Supplements to the Official Records of the Economic and Social Council. A complete collection of these supplements in print will be found in the UN Collection of the Dag Hammarskjöld Library, Uppsala, and in the libraries at UN Headquarters in New York and Geneva.
Recent supplements are posted as Reports at the ECOSOC official Web page.
Documents are published electronically from 1993- in the United Nations Document System - ODS.
References to documents with links to full texts for recent years can be retrieved through the UNBISnet - the online catalogue of the UN Libraries in New York and Geneva.
