Intergovernmental Organizations (IGOs) are comprised of member states or other intergovernmental organizations. IGOs are created through treaties that act as a charter for the group. Usually an IGO is formed with a purpose, sometimes broad and sometimes relatively specific. The United Nations, European Union, World Health Organization and International Monetary Fund are examples of well known IGOs, but there are many others, often with much more specific regional concerns.
Publications from IGOs are not the equivalent of scholarly peer reviewed articles, but in many cases they provide important source material for research. IGOs often track issues over a long periods of time, and provide in-depth analysis of issues from a multi-country governmental perspective. Some key sources are listed below. For a full list of IGOs and their websites see the Northwestern University list of IGOs.
Every country collects data a little differently, and may have slightly different definitions for terms. IGOs take information reported by various countries and normalize them so comparisons can be made across countries and across time. If you ever want to compare two countries, IGO data should be your first choice if avaialble. (But it is still important to read about the methodology behind the data!)
If you are studying only one country, or need more detailed data or statistics than is provided by an IGO, the statistical department of a country's government may be your best source. See Northwestern University's list of foreign government websites, including statistical divisions for more.
The SLU Libraries have many relevant books on IGOs. Here is a sample of what we have to get you started. If you're interested in a specific IGO include the name in your catalog search to find books on the organization.
NGOs have no governmental affiliation, and can operate on a national or international level. They usually have a clearly defined mission and will work to achieve that mission through both work on the ground and think tank-like operations. As a result, NGOs can be a rich source of research information from qualitative studies, as well as the statistics they collect through their work. Examples of international NGOs: International Committee of the Red Cross and Democracy International.
To find potentially relevant NGOs see Bond's Membership Directory of over 350 NGOs working in international development.
