Re: Copying & Printing
It's called fair usage. You're allowed to photocopy smallish exerpts of a book (from memory, no more than 10%), but not the whole book. Enforcement is usually informal, by means of the library's photo-copier. It typically costs 10p/page, some of which is fed back to book publishers although they can't know what was copied. That also discourages excessive copying: 400 pages at 10p/page is £40, and the majority of books cost less than that. And of course, if you use the copier for too long, the librarians will investigate what you are up to.
There's a HUGE loophole in that if you can borrow the book, you can copy it on some other scanner or copier! In my UG days, the publisher had allowed a recommended book to go out of print, and every student had an "illegal" copy.
It ought to be straightforward to link a dedicated terminal displaying a scanned book to a library printer, in such a way that fair usage rules are enforced.
I'n recent years I've taken to using my phone to photograph exerpts, rather than pay to use the library copier. Don't know what the rules say about that, but I feel it's fair. So far the librarians have ignored me. The copy is inferior. It's mainly a way for me to time-shift by study of the exerpt rather than anything that I want to keep long-term. (It occurs to me that taking photos of a screen is easier than taking photos of a paper page).
