I'm selling my used "R seau - Communication, Int gration, Intersections" by Jean Marie Schultz and Marie-Paule Tranvouez. I will delete this post once it's sold. It has an on-line access code that I did not use when I bought it because I purchased an on-line code before I bought the book. In terrific condition. The cover has wear marks but all pages are fine. I'm asking $80. Merci !
