Yes, the book doesn't do Lisp justice, it is too short. But at the current volume, I had something at least passing muster; I'm toying with extending it but that depends on feedback/success/etc. There are a lot of Lisp implementations I haven't mentioned (or dealt with in the depth they deserve), there is a lot more to say about the sort of AI work that was (and, I think, is) done with Lisp, etc. And I have written it with a "general techie" audience in mind more than "I'm already a hardcore Lisper", I will probably disappoint the latter group with a lack of depth. I haven't aspired to LOL or PAIP or similar great works.

It's a history through a lens, but if there is one I'd say "MIT/Stanford" as a central axis rather than a field of reesarch.

And Javascript? My own choice. The amount of "language" I needed was very small and I actually like the very minimalistic (lisp-y?) sort of Javascript you can write these days if you just ignore most of its history. It's accessible, that was more important to me than anything else - one of the few concessions where I wanted to make things digestible to as wide an audience as possible in a language that was good for the problem at hand. Strangely enough, it worked very well (I think).

I heard your (and others') request for a better sample chapter than the intro that Amazon shows, I'll put it on the site as soon as possible.

https://berksoft.ca/gol/genius-of-lisp-chapter-8.pdf is the chapter on Scheme, now on the book's site as a free sample. Hope you like it.
