When searching for information on the "free web", you need to be critical. Here are a few reasons:
- anyone can post anything on the web
- the amount of information online can be overwhelming; there are currently more than 124 million websites in existence
- many websites have an agenda, and may be trying to sell you something
- search results bring varying results, only some of which may be relevant for your research
- most scholarly sources are not available on the "free web", but through library databases
