I always pirated PDFs of my textbooks, but in the few cases where I couldn’t find anything online (typically when the book is niche and very new), I would always wait until I knew that I actually needed the book, because it was frustrating how often this meme came true.

I had this one professor I was really grateful for though. He was a big open-source guy, apparently used to contribute to freebsd and postgres, and he went out of his way to find open-source textbooks for all of his classes.

I don’t know how long ago that was, but the hustle has long ago counter measured pirating or second handing the books by bundling the new books with a 1 time use code to make a profile into the online part of the course where you have to take tests. You could just buy the code on its own when I was going through this, but the code was like 80% the cost of a code and book.

They also do the thing where questions in the book will be scrambled from edition to edition, so using an older copy of a math book for example won’t track because they’ve arbitrarily changed it just enough.
