Gather basic facts, definitions and background information from reference books-- specialized encyclopedias, dictionaries and atlases. Search within individual books or search multiple books at the same time.
Search for relevant organizations by using keywords for your topic, then the words "and organization." Sometimes the keywords themselves are all you need to see organization websites in your results. Evaluate your results and read the sites carefully to check for bias. Some--but not all--organizational sites have a .org domain name (part of url).
