Back when I was teaching I seriously advocated printing textbooks on newsprint with the cheapest possible binding.
Science progreses too fast for anything else; although in the basic human anatomy course I did suggest to students that they purchase the oldest book they could find and I'd let them know about any updates.
What is the info from this guy and what grade textbook is it in?
Take your pick!
