Wikipedia vs. Textbooks

Personally, I like Wikipedia for brief summaries of a topic, but I do not always trust everything that is written. That is why teaching a class based on Wikipedia seems unrealistic, because there is not usually enough detail and not all the facts can be trusted. As far as Wikipedia vs. The textbook goes, Wikipedia actually gave a very good overview of Buddhism. Wikipedia organizes it all into subheadings, such as origin, founder, and customs. However there were a few facts that contrasted with the textbook's, and I trust the textbook over Wikipedia. I believe if you need a five minute summary of a topic, go to Wikipedia. However, if you want to prepare for a test and learn in depth about something, the textbook is the only way to go.
