We are thinking about buying new textbooks for our students. Is there an established practice of buying digital copies of books for students? I expect that e-books should generally be cheaper and we might also be able to save money on delivery.
If the school were to purchase 10 copies of some particular title (e.g., this condensed matter physics book), would it be possible to loan these e-books to one set of students for some period of time (2 years), and later use the same licensed e-books for the next set of students?
I'm asking is it legal to give the same e-book file to multiple student generations, given that the particular licensed copy is only used by one student at a time.
If it is legal, I'm interesting in the established procedure for doing so. Are there any special considerations for different vendors or for different e-book formats?
