Nice book, but slightly outdated. The first part (which is included in the PDF) is fine.
Erlang/OTP documentation
There is no main site for CL, so I will have to put more links here than for the other languages.
Some links mention Scheme, which is a different programming language. Advice: don't read Scheme tutorials when you are learning Common Lisp!

Very nice book, but written in an inspirational style which means that it is a bit weak on details.

After looking through a number of web resources for CL I decided I like this one best. One problem though—he does not present CL as a functional language.
Not available on the web. Nice tutorial and good documentation of most of the language.
Some chapters can be found here: http://www.paulgraham.com/acl.html
SBCL and Slime
If you use Ubuntu, SBCL and Slime (and all other software used in this course) can be installed with the package manager.
Uses simple games to teach Common Lisp.
The hyperspec. Useful but contains a lot of things that are not relevant for beginners. The two links contain the same material in different styles.

(This page is well organized and contains a ton of links and other useful information, so I don't need to say much about Haskell here.)
