Search using your keywords, then restrict your search to 'Scholarly & Peer-Review' (for example) by using the filters in the column on the left to narrow your search.
Scan entries for new terms to use in your next search.
Another path for locating scholarship is to use Google Scholar.
Google Scholar defines scholarship more broadly than most of your professors, so always double-check to make sure what you're finding is suitable. Google Scholar also includes much material which is not available in the library databases (but is typically available through interlibrary loan).
If you are not on campus, you need to adjust your settings in Google Scholar so it can search the library's databases.
For more information about effective use of Google Scholar, see our handout.
