Emacs Lisp for the Common Lisper?

Are there any good sources out there for how to write good Emacs Lisp
that don't make the assumption that you don't know Lisp in general? I
ask because there seems to be quite a lot of Emacs Lisp knowledge out
there that's part of it's extensive library of Lisp functions, but the
tutorial stuff I've found spends a lot more time talking about what a
cons is and what lambda means than it does about how to actually use
the Emacsy parts if you already have a decent handle on the Lispy
parts.

TIA,
Pillsy
