You can start with SEARCH EVERYTHING - which searches most of the library databases at once. Then use General Article Indexes like Academic Search Premier and Lexis Nexis. These cover a wide variety of subjects and include a mixture of newspapers, popular magazines, and scholarly journals.
Is your topic in a particular subject area?
Then use a subject index which specialize in a particular subject, the articles are generally from scholarly peer reviewed sources.Examples are IEEE (Engineering), Avery Index (Architecture), and Business Source Premier (Business & Management).

A database will show you articles that match for your search terms.
