Since when can you not get an ISBN for Textbooks! I am taking an Online course this semester and the book is $120 from our bookstore, so i need the ISBN to try to find it elsewhere cheaper. This was my Response from our online bookstore: Thank you for your email. MBS Direct Virtual Bookstore will no longer display ISBN numbers associated with booklists. Exceptions will be made for titles that are on backorder status, and the Virtual Bookstore will show ISBNs in these circumstances. This policy change is standard throughout the textbook industry, and will help insure that students have the correct course materials by ordering from MBS Direct. In addition, our contact center will no longer provide ISBN numbers over the phone. You may wish to contact your school for this information. Is this true that this is standard policy in the textbook industry?
