We also have posters up in the A-V areas drawing users' attention to copyright restrictions and educational use only. We have a standard sticky label with words to the effect that it is only to be used for education purposes. However, we don't say on the sticker that they shouldn't be copied. Where we get enquiries at any Media Service point from students wanting to make their own copy, staff will question them or direct them to me in order to ascertain why the copy is required and if it's legal and appropriate to supply one. About half and half.
Restrictions are usually for external users or by age.
This wouldn't be allowed, after all the whole point about copyright is that you don't finanacially benefit from someone else's work without their say so. Charging for loans would be doing just that.
