The Economic and Social Commission oversees five regional commissions headquartered throughout the world.  These commissions include:

• ECE – Economic Commission for Europe. Geneva. (Europe, North America)
• ECLAC – Economic Commission for Latin America and the Caribbean. Santiago, Chile.
• ECA – Economic Commission for Africa. Addis Ababa.
• ESCAP – Economic and Social Commission for Asia and the Pacific. Bangkok.
• ESCWA – Economic and Social Commission for Western Asia. Amman.

Each of the Commissions maintains separate publishing operations out of their headquarters. Their web sites can be informative and include  valuable information and publications about their respective economic regions and member countries. Regional Commissions provide selected sales and masthead documents to all depositories. However, full documentation is provided only to depositories located within the area covered by the appropriate Commission. The Regional Commission documents are selectively indexed in the major UN indexes. However, several Commissions publish separate indexes to their own publications
