These supplements are valuable resources fror students and faculty alike. Creating a new edition of a mainline law textbook is a major undertaking. Creating these supplements allows for a lobger shelf life of extant textbooks--with updates that provide currency for students. A valuable resaource indeed for those who teach Con Law courses and like this mainline textbook.
My main pet peeve with this supplement is that the editor did not even make an attempt at synthesizing the information. I didn't have a problem with the editing of the cases per se, but, for twenty dollars, the editor could well have compiled an index or something.
