Query: Not for intro courses

This is a typical mammoth intro textbook, which means it is far from adequate for intro courses. The authors assume that the student is going to devote eight hours a day to the intro course alone, a rather unrealistic expectation. There are dozens such textbooks, none practical. What the point in a many-page bibliography, which not even one in a thousand is even going to consult? It's about time we came down to earth, and started writing intro textbooks for intro courses.
