Thanks for your reply, and sorry for my lack of clarity. Let me try to be more specific.
I am the coordinator of a tutoring center at a university, in charge (among other things) of tutor training. The books are tutor training materials, and what I would like to do is to buy a set of these...
I am considering the purchase of (several copies of) a book for internal training purposes. The book contains the following message at the beginning:
THIS WORKBOOK MAY NOT BE COPIED OR USED BY MORE THAN ONE STUDENT. RESALE IS ALSO PROHIBITED.
<Title deleted> is a consumable classroom workbook...
