Data on the location of members and secretariats of international organizations are presented in the Yearbook of International Organizations. Secretariat staff are unable to deal with requests for contact information of organizations due to time and budgetary constraints, but we suggest the following pointers:

• Use the telephone directory to see if there is a local chapter or regional office in your area.
• Contact telephone directory assistance for local, regional, national or international contact listings.
• Contact the Reference Department of a local public university or non-governmental organization (eg British Council or American Cultural Center).
• Related local organizations should be able to provide you with information concerning regional or international organizations which work on similar issues.
• Websites of organizations related to the organization you are seeking will often provide contact information or a list of relevant links to other websites.
