If you are like a lot of people, you start your research with Wikipedia, or you use a search engine such as Google or Yahoo, and end up at Wikipedia. Encyclopedias like Wikipedia are useful places to start when you don’t know that much about your topic. They can offer a concise introduction and give you ideas for more specific aspects of an issue, as well as suggestions for important books and articles for further reading.
Issues with Wikipedia
Wikipedia is easy to access and can offer very interesting information, not to mention that it is huge, with over 1 million entries in English. But there’s one major issue with Wikipedia – anyone can write or change an entry. You never know who wrote it, and it’s a "moving target," meaning that the content is constantly changing.
Ideally, because each entry can be modified, the “wisdom of the crowd” improves the accuracy of the information. But in practice, writing by committee doesn’t lend itself to elegant prose, and the entries are better for fact-based information than for holistic, contextual information that academic experts can give you. And you have no idea of the authority of the authors.
