Databases for NSC 890

Other Considerations

Librarians will be happy to help coach you in your searches, by suggesting databases, search terms, limiters, etc.  Sometimes we demonstrate searches to model search techniques that you can use in the future.  Our goal is to help you become self-sufficient so that you can find evidence-based content throughout your professional life.
