Hey guys, I work in the textbook industry and figured I’d offer myself up to answer questions.
A few things to start:
First I will say is that there’s a big difference between “custom textbooks” that are just re-mixed versions made so they can’t be as easily re-sold. (this is a favorite practice of the Majors, i.e. Pearson, when they’re not busy bribing officials through their non-profit of course, McGraw, Cengage, etc.) and legit custom texts. Big guys do the “custom” stuff for the same reason there are new editions made seemingly every year of textbooks of topics that basically don’t change and certainly don’t need an update; to try to pump new sales out.
Remember, especially in an age where non-direct rentals and used books are easily accessible, the companies feel that they have to squeeze the most out of every book. Once that puppy is sold they stand to not profit from it ever again, even if ten students end up using that book (of course, don’t think that’s not priced into the cost of the book to begin with…).
Two, you’re probably aware that even on custom made books where you have no choice most college bookstores charge a mark up (and sometimes a significant one?).
Three, not all custom texts are a scam. There are a number of companies that are content aggregators (XanEdu, Academic Pub, University Readers) that will put together custom textbooks that do seem to actually be cheaper (and sometimes significantly so) than traditional books (and usually come in ebook format even if the original texts don’t). That’s because they’ll generally pull stuff from across content providers (which the Majors won’t do. Period. You can only mix and match their own stuff, naturally) so students can actually buy one book instead of four, etc…
Of course students do get still get stuck with the inability to sell back their books and that sucks.
Four, there’s also a movement towards “free,” open source, etc. content. Flatworld is the most famous of those providers. But, before you scream “yes! free textbooks!” be aware that it’s basically a gimmick to get you to buy other shit. The free online ebook reader that lets you read the books for free is (intentionally) crippled and the downloadable ebooks are a completely unreasonable $25, never mind the charges for open source content when you want an actual textbook.
So, that said, fire away, I’ll try to answer the best I can…
on edit: one other thing, most of the professors we come in contact with, believe it or not, aren’t out to screw the students! You’d be surprised how often professors do care about the price of books. And in how many other cases they feel embarrassed that they assigned something that was so expensive without investigation.
