Most of the information you need will be found in databases. LVC's A - Z Database List tools can help you narrow your database choices. Using the pull-downs, focus your choices by subject and by the type of information you need.
Limit your database search by choosing a specific subject. Recognize, too, that sometimes your topic may straddle several subject areas (for example, the broad subject of mental health counseling could fall within both psychology, sociology, and also education (if the counseling occurs within an educational setting). If your topic does straddle several subjects, pick the database that's most appropriate, but explore databases in other subject areas, since it's always best to get multiple viewpoints.
The type filter can be invaluable if you know what type of information you need--peer-reviewed articles, magazine articles, books, etc. From the title list of LVC's databases, focus your search by using All Databases Types filter. Or...focus your database search by both the subject AND the type!
We have research guides for almost every major/department on campus. Each guide has a page linking to the major databases and resources in that field.
