Have you ever tried searching for scholarly information within Google and find that you are searching through a lot of results without much success? Google Scholar is a powerful search engine for your research needs. It provides the broad spectrum of information all within a single search engine. There are also other features under the Advanced Scholar Search if you happen to know the exact title of an article or if you just want to narrow the results to a more specific area. Even if you just want to narrow the results to specific dates, you can do that too.
And if you like to use Refworks for your bibliography, you can even have the results pull up sites that can be exported into Refworks by changing that within the Scholar Preferences page.
