Whenever I want quick reference on something, for instance, when I'm watching television, Wikipedia is great. It covers so many unexpected subjects. In actual fact, it is somewhat moderated, and not just anybody can edit some subjects. That aside, as a retired librarian, what I really like about the Wikipedia articles are the references to other resources given at the end of the articles. These are the most important for verifying the information in the Wikipedia article. The references may make Wikipedia more valuable for a research project than the actual Wikipedia articles. Wikipedia may be best used as a spring board to finding good resources. The internal links in the articles are useful, but you must remember, they are internal and can be just as erroneous.
