1) Anybody can contribute information to or edit Wikipedia and there is no way of telling who they are. Use your judgment when determining if information is correct.
2) One of Wikipedia's greatest strengths is that it provides an in-depth overview of a topic with links to the original source of information. All good entries will give you many places to consult for further information.
3) According to Wikipedia guidelines, entries should be neutral and present the facts without bias. Be cautious in using information from an entry that seems to favor only one side of an argument.
4) Information in Wikipedia may evolve over time. It is a good idea to periodically check for updates on a topic if you are studying it over time.
5) Links in the Notes and References sections may not provide you with the full text of that resource. It is a good idea to search for these items at the MSU Libraries.
