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.
