Google Scholar has all the power (and problems) of Google, but only searches the educational materials in Google. There are diamonds amongst the dirt out there, so it is worth searching. But don't be surprised if the fulltext is not available and you are asked to pay for content. Don't, we can get it for you free via Interlibrary Loan.
