hmm, as a 3L , here are some of the books that works for me as i remember em
crim law: dressler, understanding
civ pro: emmanuel (my class loved examples n explanations - but i found it to be too much of a painful slow read..)
con law: chimerinsky
property: didn't use one cuz my prof taught mostly ny law
torts: a small green book, maybe gannon or something?? forget name - sry
contracts: didnt need one cuz prof rocked
anyway - i bought a bunch every semester, and one of the things about hornbooks is that they usually have decent resale value on amazon etc .. my suggestion is buy a few and see which one works best for you and the subject matter that ur prof teaches..
