For those who have iPads, there is a free app as well by the same name. Essentially it "scrapes" a number of reliable web resources for information on a topic of choice. Then it puts the information together in what looks like a "Trade Book" found in the Non-Fiction part of your library, filled with engaging pictures and short summarized pieces of information. Finally, it reads the article to the user.
This is a tool that could help students not to simply copy and paste wikipedia articles as they are preparing research.
