What is Wikipedia?

Wikipedia is a free, ad-free encyclopedia written by volunteers, with millions of articles in more than 300 languages and references for further reading. It is run by the non-profit Wikimedia Foundation, and its content is openly licensed, which makes it a fast starting point for almost any research.

Pros: what Wikipedia does well

  • Free with no ads
  • Huge range of topics
  • Sources listed for checking

Cons: where it falls short

  • Quality varies between articles
  • Should not be the only source for serious work

Who Wikipedia is for

Anyone who wants a quick, well-referenced overview of a topic before digging deeper.

Who can skip it

Researchers who need peer-reviewed primary sources only.
