I just noticed that August 17 was the 50th anniversary of the LISP 1.5 Programmer’s Manual by John McCarthy, Paul W. Abrahams, Daniel J. Edwards, Timothy P. Hart, and Michael I. Levin. On that day in 1962 it was published as a bound report of the Computation Center and Research Laboratory of Electronics of the Massachusetts Institute of Technology. It was also published by MIT Press — perhaps simultaneously — and is still in print. A second edition was released in 1965; the only difference that I see comparing tables of contents is the addition of Appendix I: LISP for SHARE distribution.
This was of course the first book on LISP. It is a reference manual rather than a textbook, but many people managed to learn LISP from it, and a number of people managed to implement LISP from it. Today ACM’s Digital Library lists 327 citations for it, and Google lists about 23,900 hits. I’m pleased to say that #1 on Google is the authorized PDF at my History of LISP archive at the Computer History Museum.
Through the generosity of several people, the History of LISP archive includes not only the book but also several versions of the underlying source code:
- LISP 1.5 Programmer’s Manual by permission of MIT Press;
- September 1961 snapshot of the source code in PDF and ASCII formats, courtesy of Timothy P. Hart, M.I.T. Museum, Jack Harper, Pascal Bourguignon, Rich Cornwell and Bob Abeles;
- Snapshot of CTSS version of source code, courtesy of Robert R. Fenichel;
- Snapshot of SHARE distribution of source code, courtesy of Dennis Allison and Al Kossow.
If you’re resourceful and you’d like to actually run the system described in this book, you don’t need an IBM 7090 or a time machine; the SIMH simulator package and the files and information here are sufficient; scroll down until you find “Running Lisp 1.5 in the SIMH IBM 7094 emulator.”
