When looking for news, try Westlaw or Lexis first, for their more powerful, precise search engines and for greater depth of coverage, especially in time.
As you sift through results, look for original reporting.
When a story mentions a report, study, agency, or group, search for the report, or for the group or agency web site.
Even though Westlaw and Lexis tilt toward business news and English-language sources, they still have several useful collections of newspapers and other news sources from around the world. This page links to the best of those sources. (You will need your own valid passwords to connect to these sources.)
