One of the first things I do when I am doing research or work is turn to my old trustworthy friend, Google. When Google first came out I didn't want to use it. I was a staunch MSN search user (mainly because it was the default and I hate change), but as I was exposed to Google more and more I made the transition and haven't looked back! Google is a powerful tool for doing pretty much anything from searching the web to finding driving directions. Here are some links for you to add to your toolbox.
Google (Go to Preferences to customise it to your country)
Google University Search
These tools are extremely useful for doing research or homework, especially when you tweak with the search settings.
