The Common Lisp HyperSpec (CLHS) is a non-free hyperlinked version of the ANSI Common Lisp Standard. It may be downloaded gratis but has certain restrictions that make it strictly speaking non-free. Also available in Debian as package hyperspec, and from Quicklisp through the clhs ASDF wrapper: (ql:quickload "clhs").

You may find an online version of the HyperSpec at:

The CLHS index prior to version 5 does not index either format operands or # read macros very well. You want to get version 5 or newer of the CLHS. If the CLHS has a gray background, you have a version which was released prior to version 5.

Hyperspec references may be embedded into CLiki pages. See the Text Formatting rules for how.

If you are using Emacs, you can use clhs.el which comes with CLISP.
Tip: If you want it all in Lisp, you can make Erik Naggum's hyperspec.el open HyperSpec-Pages in Closure. Sample elisp code using ELI:
 (setq browse-url-browser-function 'browse-url-closure)
 (defun browse-url-closure (url &optional new-window)
   (fi:eval-in-lisp "(closure::visit \"%s\")" url))
