If you are researching a company, start with Business Source Complete; in there, you can find SWOT analysis, corporate news, product news, etc. If you are researching a country, start with CIA Factbook for background information and more in-depth facts on the country.
You will need to locate three solid resources.
The CIA World Factbook is a useful tool for finding information on specific countries and the issues they face. Use reports to get a sense of the cultural, political, economic, and geographical concerns to help you hone in on other topics to research.
Use reliable news sources like the BBC, NPR, CNN, and other news outlets to help you understand a specific country's relations with other countries. Most of these outlets have archives that may help in providing you with background information on the issues involved.
