Wikipedia vs The Book

There are some pros and cons to using either wikipedia or the history book. I personally prefer wikipedia, but the book is also good for other things. Wikipedia is easier to use and makes it easier to find things. All the main categories are broken into subcategories that are easily navigable. However, wikipedia has one downfall that being the information. The information is not as detailed as in the book. It is also editable by anyone worldwide, so there is no way of knowing if the information is legitimate or not. I think a class using wikipedia would be pretty cool, but for homework I prefer the book because of the full information and reliability.
