Not really sure where to post this (and probably it's a bit out of place on this forum), but I've recently noticed that some of the classic textbooks for undergraduate math courses (in particular, Herstein's Topics in Algebra and Artin's Algebra) are no longer offered by their respective publishers (Wiley and Pearson) as hardcover books, and instead they only offer softcover print-on-demand copies for roughly the same price. Even Baby Rudin is now listed as "either hardcover or softcover" on the publisher's website when you purchase... not at all clear they won't just send a softcover copy.
I noticed this when looking to upgrade my copy of Artin from the 1st edition to the 2nd (looks like some better organization and many changes in the exercises) and to replace a lost copy of Herstein (a personal favorite).
And yet the books are still being sold for astronomically high prices (upwards of $200 for a soft-cover, print-on-demand book!)
Granted I haven't purchased these books new in a number of years, but this seems like an absolutely outrageous rip-off. How are professors/lecturers dealing with this? These books are absolute treasures, and every undergrad should be allowed to enjoy them and learn from them. I should note that I currently work in industry (math grad school in a former life, but I still enjoy reading and studying mathematics), so I'm a bit out of the loop.
