10. All information is not available on the Internet.
It seems like everything is supposed to be there; it's the best thing since sliced bread. But much of the most valuable information for academic research is not found by popping a search term or two into Google or Wikipedia.

In fact, books and journal articles contain some of the most stable and trustworthy information available. Use the Library Catalog for books, and resources such as FirstSearch for articles, to find the best information!
