This page is a overview of elisp references.
For a short encyclopedia styled intro about elisp, see: Wikipedia: Emacs Lisp.
If you are not already familiar with a programing language, see: “An Introduction to Programming in Emacs Lisp” by Robert J Chassell. (1990,...,2004) At: http://www.gnu.org/software/emacs/emacs-lisp-intro/. This is bundled with emacs 22. To view it in emacs, type “Ctrl+h i”, then click on the “Emacs Lisp Intro”.
The official doc for elisp is the “GNU Emacs Lisp Reference Manual”, written by Robert Krawitz, Bil Lewis, Dan LaLiberte, Richard Stallman, Chris Welty, Robert J Chassell and others. (1990,...,2006). To view it in emacs, type “Ctrl+h i”, then click on the “ELisp”. A downloadable, pretty-formatted HTML version is available at: http://xahlee.org/elisp/index.html.
Both the elisp intro and the elisp manual are extremely well-written. They are the highest quality technical writing in the info tech industry.
