Then students will just end up paying more in tuition, possibly more than the costs of textbooks. That extra money of course will go to increasing either/both the university president's or lead football coach's salaries.

The colleges will raise tuition anyways, and they do it at a runaway cost. Might as well throw in something useful and tangible like textbooks that they can bargain wholesale with the publishers. Individually, the students can only beg.

Copyright stifles creative output. I believe that if we got rid of copyright (not just for textbooks), the quality and quantity of published work will increase.
Zigurd•1h ago
Copyright term kept getting extended. Copyright was a controversial concept when it got baked into the US constitution. But the enabling laws have run off the rails, mainly due to corporate lobbying. Copyright has also been reinterpreted as a property right, when it's really a government granted limited term monopoly. Another case of the government being bought out from under the people.
zeroonetwothree•1h ago
Why would people author published works if they won’t get compensated? Countries with weak copyright enforcement don’t tend to have better output than the US (I think most would argue it’s worse).

I do agree the term is too long, I would support something in the range of 5-20 years.

That's an odd question to ask given the history of free media like flash games, youtube videos, deviant art/pixiv/etc, and fan fiction. Getting paid, especially enough that one can make a living off of it, for your creative work is an exception not the rule way more people create it for no money than ever make any money at all much less a living.

I read this book cover to cover after purchasing it with money, despite it being free online, and loved it. I think it’s pretty clear that the author was in a position where they could afford to put this out there for free. But not everyone is and I think people should be compensated for their time and efforts if that’s what they want.

Buying used global editions from the international students is the move for undergrads at big schools. Hardcover binding and color print were not missed and definitely not worth 10-20x more. Even published lecturers would ask students to fetch a "course pack" compilation of sloppy photocopied excerpts for purchase by on-campus print operations. Somehow this wasn't piracy. It is no secret that publishers and booksellers have an incestuous relationship with education institutions and aggressively extract pounds of loan debt flesh from the student body.

Piracy?! What do I look like, an AI CEbro pillaging intellectual property for monopolistic commercial advantage without material consequence?!

For a time, course packs were the piracy of convenience because a PDFs with well-meaning but unreliable OCR were loaded with images (charting etc) resulting in large, difficult to navigate files even at the most eye watering, illegible compression.

"We required the students to buy the book"

This was always so odd to me. I used to think it was just a US weird thing but I understand it happens in many more countries as well (and maybe in my own country as well; I did go through my first degree literally two decades ago, and only at one university). When I went through my first degree, the lecturer provided the material - lectures and some handouts. Every so often there would be a reference to some book for some particular additional topic, but it was never required.

lgcmo•53m ago
In our system, the university libraries filled 90% of our textbook needs. Some books were highly sought after, especially physics and calculus, which were common for all STEM majors.

In those cases, we would run to the library first thing to get the books. If you missed out, someone would give you the PDF.

Professors would email the reading list before the first class with their recommendations, and even tell the students which libraries had each book. Other professors would have their notes and handbooks available on the website, and have some of the copy shops sell them for the cost of printing.

Xotic007•1h ago
OSTEP is genuinely one of the best OS resources out there. Hard to argue textbooks should be behind a paywall when the free version is this good.
CM30•1h ago
They should at least be free through the university, given the insane prices students paying for tuition now. Maybe it could be sold for money to those not actually attending a course on a subject, but I hear of far too many examples where it seems the lecturer/professor is basically using the students as a secondary way of making money.

And the online setup is arguably even better for the reasons noted. Perhaps in that case, paying could be something you do if you want a hard copy of the book to peruse without a computer/mobile device.

vonneumannstan•1h ago
Perhaps you fail to see how this would probably lead to textbooks costing even more and which will be directly passed to students as higher tuition?
michaelmrose•56m ago
You are assuming that the actual cost of a textbook on math which hasn't changed in centuries is hundreds of dollars per student per class when in actuality without the profit incentive a 100M could use the same ebook over a decade wherein the unit cost is almost too low to measured even if pay excellent folks to produce a new work.

The best textbooks I used in uni were either free or extremely cheap (Linear Algebra done right comes to mind, it was 30-40$, and at least the most recent edition is completely free online. I can't remember if the edition that I bought had that option). More than once I had a professor who was in the process of drafting a textbook or had already written one and it was simply given to everyone in their section for free. Paying hundreds of dollars for intro mathematics books that were glorified collections of practice problems just to get access to the online homework was insulting compared to the care put into those texts some professors gave out for free.

I wouldn't expect every professor to write their own, but I think universities should at least work on some sort of in-house solution for the intro text problem that all the instructors could use, especially public ones. It is absurd that most of those courses are structured to gate homework grades behind an expensive purchase of what is usually a sub-par text.

Wikibooks exists to allow people to collaboratively write textbooks, so every professor doesn't have to write the entire book https://en.wikibooks.org/wiki/Main_Page

I recall a university in canada had professors w=usi g their textbooks they authored but each edition was exxactly the same but they would change the quiz/assignment or exam questions so you had to buy it

on top of that we had to purchase a weird accessory to answer questions electronically instead of raising hands and he was a beneficiary of the company that built it

its so corrupt these textbooks were very expensive but we use like 1% of it

then bunch of students started photocopying and selling it at 95% discount and they got arrested with full on SWAT gear

it made me question the whole higher education thing i certainly do not encourage it anymore especially with LLMs now

Unless you plan on engineering, law, medicine, actuary i just dont see the point

I remember when the university where I worked made a big show out of moving to online textbooks. It was supposed to reduce the cost, reduce the need to lug books around, save trees, any rationale you could think of was thrown into the mix.

In the end, books didn't get any cheaper. E-books cost about the same as renting a paper textbook for the term, the DRM protection was cumbersome, if you had to go online the websites were slow. They just didn't solve any real problems, and didn't save much money.

In fact printed books are still widely used.

eszed•55m ago
When I taught university, I put every required book on reserve in the library. I also <wink-wink nudge-nudged> about "alternative methods, that you're absolutely not allowed to use. The college gets kick-backs from [book publisher], so your nerdy friend who obtains his books for free is in direct violation of that agreement, and he should absolutely not share anything with anyone in this class".

I encouraged my colleagues to make the same announcement; some did, though others were too square to do it. We all thought it was a racket, though, and tried to minimize costs. Even the colleagues who wouldn't go as far as I did regularly photo-copied pages and pages and pages of material to hand out - I think our general ethos was anything less than a chapter or so shouldn't require a purchase. Maybe that department was better than most, but I know lots of academics are aware of the situation, and think it's terrible.

It always annoyed me that I'm paying thousands of dollars for tuition, only to be forced to pay additional thousands for the university-specific version of a textbook.

I took a summer course on differential equations at Valencia Community College in Orlando in 2010. It's a perfectly fine school and it was a fun course (I really liked the professor), but what really annoyed me was that it required a $150 textbook on differential equations, and very specifically the "Valencia Edition" of it. What was even more annoying, the "non-Valencia" edition of the book was on Amazon, new and hardcover, for $26. Oh, also, the Valencia edition didn't even have a cover; it was pre-hole-punched and I was expected to put it into a binder.

Valencia might be a fine school but as far as I'm aware they're not doing cutting edge research into differential equations, and even if they were I doubt that those changes would materialize in an introductory course, so it really annoyed me that they were charging a $125 premium specifically because it would have different practice problems.

Now, in this particular story there was a happy workaround. I approached the professor after class and explained the situation to him. He said "oh dude, the homework is actually optional in this class anyway, your grade is just the tests. Just buy the cheaper book and come to me after class and I'll see if the practice problems align with what I wanted you to study." I returned the Valencia edition (which hadn't been opened) and ordered the Amazon book, and I got an A in the course.

I think it should be like in high school. You borrow the book for the semester and return it, and you only pay for the book if you damage it.

ETA:

I should point out, this is actually something I really respected about Western Governors University almost immediately. The books are digital, but they are included in the tuition.

The reason abusive textbook practices persists (i.e. instead of free/shared) is because students and parents direct their anger and complaints in the wrong direction.

Specifically, the people making you waste money with bi-yearly re-releases, one-time-codes, or $150 textbooks, isn't actually the publishing houses. It is the gatekeepers at your very school: professors, department heads, and or the administration. Publishers are acting in an immoral way, but publishers by themselves have no power to force you into this abusive relationship. Your school is the one enforcing this, and yet few students file complaints at their school about the situation, protest, or otherwise make it an issue at THAT level. The level where they actually have leverage, and their complaints are more likely to be taken seriously.

Instead accepting the financial relationship forced upon them, and complaining that they wish publishing houses were less abusive. Publishers actually have little to no power themselves to force you into giving them money, your school does. So start complaining loudly and often at the school level if you want to see change. Every single year, every single class.

Higher ed instructor here and -- yeah, no. It's the publishers.

You're speaking as if we, as professors or administration love this system and strongly benefit from it. We don't. It's just inertia.

There are existing free textbook publishing organizations. From a satisfied consumer point of view: https://openintro.org/ and https://openstax.org/.

> I first came into contact with this high-cost/low-quality problem as a student

The challenge with this perspective is that it focuses on monetary cost (what I have to pay to take a class) instead of positioning knowledge transmission repositories within a value framework.

anticorporate•33m ago
Textbooks being expensive has nothing to do with the textbook. The textbook as an actual object of learning is irrelevant; a textbook is just a fee added on to the cost of the class that happens to come with a physical pile of bound paper that may or may not be useful. It's unfortunately a rather regressive fee that also generates a lot of landfill waste.

There's little to be said about the way the economics of higher education have gone in the past few decades that's been positive for either students or educators, and this is just another symptom of it. As someone who's live in a college town for most of his life, it's rather depressing to watch the n-order effects.

The media you cite are still copyrighted, meaning that it’s illegal for other people to distribute them or make money of it without a corresponding license. If that weren’t the case, creators might be more reluctant.
rtkwe•41m ago
They know full and well they're unlikely to ever make money on there art so the protections such as they are aren't material. In fact their copyrights are often roundly ignored online with copies spreading freely a thing that's success for most of the people posting things for free!

If the justification for copyright is supposed to be that it and the promise of control of their creations is the encouragement to create people creating for free is a direct contradiction of that thesis. The fact they're automatically given copyright doesn't mean they're creating it because they have that theoretical control.

The Fortress of Doors blog had a good article on the history of flash game development. That article included an overview of the process, in which an explicitly-considered step was "after you upload your .swf file to the site that paid you to display their logo, every other site rips off the file and republishes it themselves".

That's why what the first site paid for was having their logo displayed in your game.

fluffybucktsnek•1h ago
The most basic incentive is for the fun of it. There are plenty of people who publish stuff without hoping to get directly compensated for it. Even otherwise, ideas have a nasty habit of breaking free from the first authors, specially without laws to prevent such.

Also, copyright isn't about compensating authors, but publishers. Authors are basically an afterthought.

In regards to countries with weaker copyright enforcement, I think there's a bit of an inversion. Most countries that fail to properly enforce copyright do so due to a lot of structural issues, which also hamper creative thinking for independent reasons. China would be an example of a country with weaker copyright enforcement but also with good infrastructure, and it seems to be overtaking (if it already didn't) the US in terms of creative production (both for copyright and patents).

layer8•53m ago
> Also, copyright isn't about compensating authors, but publishers.

That depends on the country. There are moral rights [0] which are usually non-transferable from the authors. That’s especially the case in the European tradition of copyright: “In most of Europe, it is not possible for authors to assign or even broadly waive their moral rights. This follows a tradition in European copyright itself, which is regarded as an item of property which cannot be sold, but only licensed.”

[0] https://en.wikipedia.org/wiki/Moral_rights

fluffybucktsnek•43m ago
Interesting for a later search, but moral rights aren't about compensation though:

> The moral rights include the right of attribution, the right to have a work published anonymously or pseudonymously, and the right to the integrity of the work. [...] Moral rights are distinct from any economic rights tied to copyrights.

Also from [0]

> Why would people author published works if they won’t get compensated?

Do you think no one was publishing anything before the year 1500?

I mean, your question is basically right. People won't do things if they won't get compensated. But copyright isn't even a large portion of the compensation people get from authoring works.
