Google Scholar is a search engine specifically for scholarly journal articles, books, dissertations, and technical reports. Use Google Scholar to find articles from a wide variety of academic publishers, professional societies, preprint repositories and universities, as well as scholarly articles available across the Web. Much of this content has hitherto been locked behind subscription barriers and not accessible to search spiders.
You can access the full text of articles from open-access journals and preprint repositories, as well as preprints on the Web. You can access the full text of articles from subscription journals if you or the University of Delaware has a subscription to the content.
