Hey everyone, I was thinking that a PhysicsForums group or topic "thing" devoted entirely to a single textbook would be popular. For instance: as I take "Electromagnetic Theory" with Griffiths "Electrodynamics" (Spring 2010, U-Minnesota Duluth), we could have a "Griffiths Electrodynamics" (group or topic "thing") existing. It would be a nice archive, too, of stuff people have, in the past, struggled with. Should we? Could we? How do we? Thoughts? Does it already exist, and I need only be pointed to the link?
