A warning about all search engines: the results you receive are based on many things such as your previous searches, paid advertisements and even what your search engines believes best fits you needs. Different browsers usually produce different results and rarely do two people show the exact same results even when using the exact same key words. Beware of what Google and other search engines return and apply the source validation tools we discussed to each result so you can decide if the information meets your needs. Don't believe me?

Search Engines
A search engine searches only one small part of the internet at a time. Each engine works on algorithms designed to prioritize different items hence, if you use the same keywords in different engines your results will differ.

Try these from home - they are blocked by our school's filters: Internet Archive - stores webpages from previous years so you can go back and see what web pages looked like during historical events.
Meta Search Engines
Meta search engines work with several search engines at the same time. They send your keywords to each of the search engines they work with and then compile the returned results.
