Bert Burgemeister has a very nice Common Lisp Quick Reference available for download. The idea is that you print it out, fold the pages, and staple them to form a little booklet. He’s got copies for A4 and letter size paper and also files for nesting or stacking the pages. There’s also a version for reading on screen that has the pages in the natural order.
This is an excellent little reference containing short descriptions of the symbols—functions, special operators, macros, variables, and constants—defined in the ANSI Common Lisp standard. If you use CL, you should give it a look. I am going to include at least the on-screen version in my documentation set and, despite my aversion to data on dead trees I might also print a copy.
