Learning GNU Emacs, 2nd Edition by Debra Cameron, Bill Rosenblatt, Eric S. Raymond

Much better than the current, 3rd edition. The first half of the book walks you through the fundamental steps, as a tutorial.

Can be obtained from O'Reilly http://shop.oreilly.com/product/9781565921528.do

Casting Spells in Lisp (Emacs Lisp version) by Conrad Barski M.D.

Written originally to teach some other flavor of Lisp, the book has been modified for Emacs Lisp. The presentation is in a form between a comic book and a manual that educates while you have fun. The best of both worlds.

It can be read online here.
