better than wikipedia?
I have to say I don't necassarily buy that some of the text books used in college are any better than wikipedia. How do you really know who wrote them and how accurate their information is? Sure in theory they should be knowledgable but in reality? Who knows.
I would hope that the information is good in text books, but at times I find that hard to believe when they publishing companies are pushing new editions out as fast as they can.
I believe it has to have 60% new material to be a new edition? Have things changed that much in the last few years that a revision of 60% of the information is really needed?
