Common Lisp Quick Reference is a free (see file COPYING) booklet with short descriptions of the thousand or so symbols defined in the ANSI standard. It builds well on a Debian system with the packages texlive-metapost, texlive-latex-recommended, texlive-latex-extra, and their dependencies installed. On FreeBSD, (at least) ports gmake and texlive-full are required. If you have those dependencies in place, type $ make and be patient. If you end up with three blank pages at the end you can try to blank a fourth page by changing \renewcommand{\clearpagebeforeindex}{\clearpage} to \renewcommand{\clearpagebeforeindex}{} in file paper-<your-papersize>.tex.
