Looks like Google is at it again? When you have a moment, check out:
Works just like regular Google, except it returns published studies on
Your topic (with links to abstracts and/or full studies). It also will
return non-web materials.
Google Scholar enables you to search specifically for scholarly
literature, including peer-reviewed papers, theses, books, preprints, abstracts and technical reports from all broad areas of research. 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.
Just as with Google Web Search, Google Scholar orders your search
Results by how relevant they are to your query, so the most useful references
should appear at the top of the page. This relevance ranking takes into
account the full text of each article as well as the article's author,
the publication in which the article appeared and how often it has been
cited in scholarly literature. Google Scholar also automatically analyzes and
extracts citations and presents them as separate results, even if the
documents they refer to are not online. This means your search results
may include citations of older works and seminal articles that appear only
in books or other offline publications.
