There is nothing wrong with Wikipedia, at least in the main languages. It's crowdsourced and has citations (and where there aren't "citation needed" help identify that).
It gives you superficial, in depth and factual information, with links to sources for more details if needed.
There's nothing at all wrong with Wikipedia but it needs sources to cite since it doesn't allow original research and the World Factbook is an important one.
