Somewhat cynically, I think the point of many textbooks is to make money for the authors.
There is no reason why a calculus book needs to cost $200 (in the 1990’s) and get refreshed every 2-3 years. That subject has been known for hundreds of years and they rob poor engineering and science student of that $200.
Sorry, I just have a bad taste in my mouth from crap like that in undergrad. Not saying you’re wrong, just think it’s more greed oriented than we’d like to think.
