What are your favourite library online web-resources?

Hey all the librarians! :)

I thought it would be great if you shared the free web resources which you or the clients in your libraries use to make life easier. What are you favourite resources?

I have noticed that in my library many people try to learn touch typing, so they use many touch typing resources, for example, www.typingstudy.com. However, there are many, many more of these pages as well. So again, which are your favourite web resources?
