The databases below are good starting points for finding for articles on a specific topic:
Move beyond basic searching by using subject-specific article databases.
The Boolean operators AND, OR, and NOT can help you combine concepts, as well as helping you to expand or narrow your search.
Truncation and wildcards help you search variations of words that may be important for your search.
These symbols can vary from database to database, so check the "Help" or "Search Tips" options in the database you are searching to find the best one for your needs.
