Usually the consumable pages of the book (lab manual, workbook, SAM =Student Activities Manual) are separate volumes, on cheap paper, and indeed have to be purchased by each student--at least for language textbooks. Unless the instructor would accept a Xerox, the library copy would be no good.
The glossy, heavy, well-bound textbook can be resold until a new textbook comes out, though--but--- This year we have one class using a textbook which is never supposed to be resold. The glossy pages are in a binder and somebody (any bookstore dealing with the textbook company, maybe? Or the students themselves?) is contracted not to resell it. The package (with passkey to online version with workbooks and lab manuals, quizzes, etc.) cost about $100 as opposed to $200 for a similar package that has a resaleable book, according to what I was told. Since the passkey can't be transferred, it makes some sense to go for the cheaper version. As I say, don't worry about the textbook companies. Maybe the confusion is because there is a special category re. educational use in (I think) the TEACH act. You can't *digitize* something and stick it in your own course management system if it was developed as an item which students in a class like this ought to buy, or as an ancillary of such an item. Example: M. Chagrin comes to UF to teach third-year French, and the book the students buy for that course is called Hexagone. But Chagrin taught the year before at UW, where he used a book called Le Monde Francophone which had an excellent video program. Chagrin still has his desk copy of the video from teaching at UW. But it would be illegal and I would say kind of immoral to digitize the video or some of the text and pop it into a course management system to add diversity to the Hexagone course. Either the UF course should switch to Monde Francophone or M. Chagrin should, to his chagrin, find some other way of exposing his students to Francophone diversity. I think, though, that he could probably show his hard copy in class. Judy Shoaf VIDEOLIB is intended to encourage the broad and lively discussion of issues relating to the selection, evaluation, acquisition,bibliographic control, preservation, and use of current and evolving video formats in libraries and related institutions. It is hoped that the list will serve as an effective working tool for video librarians, as well as a channel of communication between libraries,educational institutions, and video producers and distributors.
