Wikipedia Vs. Textbooks

I think the text book does the better job, when it comes to getting information. Wikipedia gives very general information; information purely on the surface. When trying to find information on the origin of Jainism on wikipedia, all I got is that Chandragupta Maurya was a follower. The text book was the one who gave me actual details on Mahavira, who was called Jain by his disciples. The text book goes into more detail. I think classes should definitely be based on textbooks. People wouldn't learn anything if a class was based on wikipedia. There would be general understanding, but never details.
