Spent over a decade handling higher Ed copyright: we don't have enough information to know whether your teacher is actually violating copyright. All we see is "out of print book", which means there's a wide definition of what that means. The book could be old enough to pass into public domain or the copyright may have passed back to the author after it was no longer published. Either way, the teacher may have received permission from the copyright holder to make copies. I've negotiated gratis copyright permission with both publishers and authors hundreds of times. So, firstly, you don't know whether the teacher is within his/her right to do this. The extra cost could very well be copyright licensing fees. Secondly, assuming you're correct that they are violating copyright: something of this scope is a civil matter. That means the teacher isn't going to get a visit from the cops, she/he will get a letter from the copyright holder. Considering the book is out of print, there's very little chance anyone will care about the teacher doing this for their own class. Usually, when a book is out of print long enough, the copyright is then given back to the original author. In most cases I've encountered, the author is simply tickled that someone is still using their work since the publisher has told them that it isn't feasible to print anymore. If the book is out of print because the publisher folded, then the authors are usually thrilled because it helps them demonstrate to new publishers that there's a demand for the book. If the publisher simply has stopped printing it temporarily to dedicate their schedule to more profitable books, then they usually allow schools to reprint the content for a fee. Lastly, I've spent the majority of my professional life working in the creative field and higher education. For a long time, it was my job to find professors in the schools I worked for who were doing this and shut them down. Now, as a business owner in the creative market, I take copyright exceptionally seriously. Please keep that in mind as I say what my legal advice is. Grow up, shut up, and let it go. You've made it painfully clear that you have an axe to grind with this professor and you're petty enough to try to "tattle" on them. You're in college. Act like an adult. Copyright is exceptionally important to protect creators of original content but it has been weaponized against education. If your professor is truly breaking copyright (and, again, you still haven't shown that they have), I don't condone his/her actions. But I sure am happy that students are able to get their educational materials for a reasonable price. Why you want to hurt those students just to get your professor in trouble is beyond me. And, frankly, all you're going to do is hurt yourself and your own reputation. Edit: yeah, got a little harsh. Lightened it up.
