what are my legal rights as far as this is concerned? all my harry potter books have broken spines because i read them so young, and they sit so beautifully on my shelves. (some have suggested this is your best idea and i agree.) the experts provide the students with the assignment papers of their particular subject at any level of education. this means you can store them in the grinder for as long as you need to without wasting any of it. it made good sense to me and i understand it better.
