With thanks to Alan Apt of Prentice Hall for giving me back the copyright and Chip Coldwell for reproducing it from the original tex files, here finally is a digital version of On Lisp. [600K Compressed Postscript File] [1412K Postscript File] [1030K PDF File] This is identical to the printed version, except that nine diagrams are missing. If you see a blank figure, that's what happened. These unfortunately seem to be lost. Note: Identical means including mistakes. Please let me know if you find more.
