How can it cost $300 extra to make a hardback version of a book? https://www.amazon.com/Foundations-Classical-Mechanics-Fundamental-Theories/dp/0792353021 vs https://www.amazon.com/Foundations-Classical-Mechanics-Fundamental-Theories/dp/0792355148 When you can buy a hardback copy of Lang's Algebra (980 pages) from Springer for $68, this just seems insane to me. The strange thing is that Hestenes' book above is published by another arm of Springer. Sorry, I just felt the need to vent about book prices. I have read many interesting articles about the textbook industry. Everyone seems to know it is crooked, but I just don't see their gouging ending any time soon. If a book is good quality, I am quite happy to spend $50 on a paper version of the book (preferably hardback). However, at these prices, their customer base is going to go the way of the music industry. Paper is just too easy to scan and e-readers are now cheaper than the textbooks. Thoughts?
