A great place to start a search for scholarly articles is Library Search. Because it searches so many different sources, you will get more search results than if you searched a single database. This can be useful if you want to cast the widest net possible when doing research or if you aren't certain where to start your research. There is a check-box in Library Search to limit articles to peer-reviewed.
