When I was at UCSD (also a long time ago), I had the privilege of taking a course from a professor who used his own $70 textbook, then &amp;quot;taught&amp;quot; by reading it in front of a whiteboard.  Undergrad tuition was also going up 20-30% per year at the time, for something that could only charitably be called &amp;quot;education.&amp;quot;&lt;p&gt;There&amp;#x27;s very little excuse to create new versions of a calculus textbook.  My decades-old Thomas still works just fine.</text><parent_chain><item><author>georgeecollins</author><text>When I went to UCSD (a long time ago) the standard engineering calculus book was revised every other year, usually changing all the homework problems, destroying the used market for it.
