Until recent years encyclopedias were a large, very expensive, set of books. However, you can now access very good information about just about anything you can think of through Wikipedia. It's fast to access (you must have an Internet connection) and it's free!
You can access this free encyclopedia through the Browse Activity. Enter the following URL into the Location Bar and press enter: http://www.wikipedia.org
Now click the language that you understand from the ones provided. I will click the "English" link:
Now you have the "home page" of the Wikipedia English site open. To search for something, just type what you are looking for into the text box where it says "search":
When you have entered the terms you are looking for click "Search" and you are taken to a list of links from which you can choose or directly to a page referring to your search. These pages are the Wikipedia pages for that subject.
