When you are looking for theory on a spesific topic, you are almost guaranteed to find it on wikipedia. The amount of information you will find is incredible! Topics relating to music, literature, history, movies as well as thousands and thousands of definitions are availible for everyone who is interested in it. I even found information about my father's uncle - now that is impressive!
The question of how reliable the information we find online, especially on web sites such as wikipedia is important to discuss. The information presented is written by whoever, which means that you can not be sure that it is correct or true. In theory I could write something about myself, for example that I am the queen of Sweden, and whenever someone searches for my name on wikipedia, the information about the "new queen of Sweden" will appear. It is in other words important to be critical when you are searching the Internet for information, especially if you all of a sudden notice that there are more than one person claiming to be the queen of Sweden, or any other country for that matter.
But what can you do to check if the information found is reliable or not? I am suggesting two methods: First of all, you can search for articles that supports what you have already read from wikipedia. If the topic you are searching for is well known, such as Britney Spears, monkeys or Barack Obama, the odds of finding information elsewhere is massive. Secondly, you could try looking it up in an old-fashioned encyclopedia (if they still exist).
Despite this, there is no doubt that wikipedia is an amazing tool when you know how to use it. That however, is easy peasy. You just type the name of whatever you are searcing for, for example WW2, The Beatles or monkeys, and whoop - the page with your ordered information is right in front of you! Very often you also get to see a picure(or several) relating to your information. Perfect? I think so!
