The Internet is a terrific resource for research.  It contains hundreds of thousands of web sites dedicated to millions of topics. Use caution when searching the web, though.  Anybody with access to the Internet can post websites about topics that interest them.  These sites are not always accurate.  Therefore, it also is a good idea to learn how to evaluate web sites.  

Ask your self some questions before you start. What kind of information are you looking for? Do you want facts? Opinions? News reports? Research studies? Analyses? Personal reflections? History? Internet sources can be very useful, but they should not be your sole source of information because there are also books, journals and other publications to read. Don't forget the library!
