Google Scholar is a search engine that provides links to full-text articles to which the University Library System subscribes or to articles made freely available by the publisher. Scholar also provides articles from academic publishers, professional societies, preprint repositories and scholarly articles posted on the web. In addition, many articles are available when the University of Pittsburgh has a subscription which would work with EZ Proxy. Finally, Scholar provides citations along with abstracts of the article if it is protected by copyright.
Use "limit to peer review" or "limit to academic journals" to exclude popular magazines and newspapers from the results list.
