You should start with the 3 main indexes, Compendex, SciFinder, and ABI/INFORM.
After searching those, you may want to use
Emerald Journal Database for over 200 journals in accounting, information science, and engineereing.
Lexis/Nexis for newspapers. In general, I recommend that you do the following
- Click on News in the left column.
- Click on Newspapers and Wires.
- In the center, uncheck Newspapers and check Major Newspapers. If your event is likely to be covered in depth by a local newspaper outside of the major metropolitan areas, you might want to use the general Newspapers category, Small Town Newspapers (US) or search for results within a specific newspaper.
