THANK YOU in advance.
Dear Dr. F.
You brought some photocopy materilas to the library to reserver for course 26-212. You copied 3 capters from book "B". Due to copy right rules can only photocopy 20% of the book. But you are over the number of copies. I, therefore request that you make a decission which capaters are the important ones that you must have on reserve for your course. Please let us know as soon as possible.
