Which academic presses are the "best" in legal scholarship, i.e., which publish the highest quality new legal scholarship?  A new poll here.  This obviously excludes publishers who mainly produce casebooks and textbooks.

UPDATE:  A reader points out that MIT Press probably should have been included; they don't publish a lot in law, but they do have some prominent authors, and while it seems unlikely that they would have outperformed the top five, it would have been good to have them in the mix.  So it goes with blog polls…
