Top Law Schools

Does anyone have good recommendations on a supplement to a Federal Courts class? Specifically, my professor is using Hellman, but unless I've completely overlooked something there's none keyed to that specific textbook.

Supposedly, Chemerinsky is hands down the best.

I presume you mean this one? http://www.amazon.com/Federal-Jurisdict ... 1454804025

I appreciated principles of federal jurisdiction where the prof focused on 1983 & habeas & abstention. easy to carry & read on the bus.

Chemerinsky.
