There are several databases that you can use to find articles. Remember that databases will only include journals that are within that particular subject area. For instance, if you are interested in nutrition needs for the elderly, then you would want to use AgeLine. If you want articles on behavioral therapy interventions for anorexia, then you would want to use PsycInfo. 

OneSearch allows you to search the Cal State LA library catalog and most of our databases. It is a great place to begin searching.

* !

wild-cards for getting a root word and all of it's endings
