If you need answers and need them fast, you might consider trying Answers.com, a new search engine that is particularly good at answering "Who is..." and "What is..." type questions. As with all search engines, this is a good tool for teachers but don't expect to turn it loose on your students without supervising them. Pupils want answers to all kinds of questions but they don't anticipate (nor are they always prepared for) the kinds of responses their queries deliver.
