This is amazing. I’m tempted to read it backwards just to see the Lisp I know get more and more alien, until we reach the Benjamin Button stage of m-expressions.

I felt, like some of the other commenters, that I was close to buying the book, but that the sample on Amazon wasn't helping to support a buying decision.

But thankfully the bibliography is given on the book's Web site in full, so I just checked if the most important paper on the history of early LISP [1] was cited or not. It wasn't, so I'm going to pass on ordering the book's first edition.

Soo.... the book has a bit of a history (see the acknowledgements). When I worked with a publisher, "academic" things like a bibliography were somewhat de-emphasized and the tooling was not nearly as nice as, well, BibTeX. So we went for a very short bibliography containing works that were directly quoted. I did read the paper way back when doing research for the first chapters, but over the years the reference got lost and that's the main reason it didn't make it in.

But you're right, it (and many, many, _many_ other things) does belong in the bibliography.

The Kobo version is a DRM free epub, so you can read it wherever you like. I'm still figuring out how/where to sell a PDF, because I really, really, _really_ do not like epub for technical books. It's ok for novels, at best. Tips welcome.

The bibliography contains a typo, namely entry 5 misses an "l" in Allegro.

And a book, which I'd call "an Oldie but Goldie" could be added: John Allen's "Anatomy of Lisp" (1978) which still is an excellent read for those who want to dive deep into Lisp's interna. One might also call it a precursor of SICP, as it covers a number of introductory topics too.

Abstract: https://dl.acm.org/doi/10.5555/542865

I agree that John Allen’s book was incredibly useful 40 years ago to explain some of the nitty-gritty of implementing Lisp languages, but I can’t really recommend it today. The Genius of Lisp is fun and entertaining - something that I would recommend for the modern reader who wants material on the essence of Lisp languages with interesting history.

Adding it to the bibliography would be great, I just didn’t like the idea of someone seeing your comment, ordering a used copy of the very old Allen book and not enjoying it.

It's well worth a read for anyone who wants to implement their own Lisp. I'd say it's the precursor of Lisp In Small Pieces by Christian Queinnec though. I have copies of both.

Great endeavour. Land of lisp is still one of my favourite alternative programming books.

One thing about the sample. Is there a chance to get a glimpse of a random chapter you like a lot? Most of it seems to be foreword/acknowledgement and a bit on "what is lisp" which I suspect most who are attracted might already know.

+1, I'm this close of ordering the hard-cover version, but really hesitant when there is zero samples, not even a page or two, makes it really hard to have any sort of expectation and figuring out if the price is worth it or not.

Technical history or "internal history" is great. Regular historians writing "external history" of computing tend to focus on certain topics, such as business and economic issues, politics, personalities, or occasionally social impact, while omitting the details of the technology itself - which are often of great interest to practitioners, and which help us understand why things happen to work the way they do.

Of course people who experienced things firsthand often have interesting personal as well as technical insight. CHM's oral histories often provide a combination of both. I also always enjoy:

Or you mean he'll probably already know about the paper? Yes, I guess that's probably the case...

I did not think about it too much to be honest, I just knew that article and thought that he would really like it if he had not read it. But I can imagine somebody writing a book on the history of Lisp has already read probably all articles around on the topic.

I just did not think about it for too long.

I have some feedbak, nothing major, but I would say that a professional designer could help you improve the book cover. Right now somebody with professional experience in graphic design --or a good eye for design-- can probably see details in it that could be improved. It's a pity if you have worked on this for five years, not to present it in the best possible way.
cdegroot 12 hours ago
Yup. I'm not happy with the design. Some promised assistance fell through and so I had to scramble last minute. I've seen worse though :)

When one learns about graphic design, one ends up obsessing about these kinds of things. "These text lines need a tiny little bit more of space"... "Those margins are slighly too small"...

It's just job conditioning... At some point in my life I was playing the game of trying to recognize the fonts I was looking at in the adds and signs as I walking down the street.

I know. And frankly, I'm not even the worst coder when it comes to graphic design. I know enough to see that _something_ is off with the cover, but not enough to figure out what ;-).
emigre 12 hours ago
Yes, yes, definitely, it's okay. I like the design, actually. :) But it would be nice to have the touch of a professional, if you can.

I would say that your choice of cover design as a whole denotes elegance and taste. Look at the cover design of graphic designer Manuel Estrada:

https://estradadesign.eu/project/alianza-editorial/

Your cover remind me of that kind of style.

There are some details about the typeface, layout, and the photograph that, as somebody with a certain background in graphic design, I can perceive as a little bit off.

The photograph was chosen because I could not find other computer books with that somewhat harsh color scheme, and you gotta stand out :)

Ok I looked at the bibliography. Best I can say is that this book might be ok for a cross-section of Lisp history but I'd like to see something much more thorough, especially regarding early Lisp, and with more of a PLT perspective. Why all those citations of Gödel but nothing(?) about typed lambda calculus or the Kleene-Rosser paradox (that Church's untyped lambda calculus is logically inconsistent)? Do you have anything about Lisp 2? About significant Lisp applications like Macsyma, that drove the language's development?

It would be awesome to have a comprehensive Lisp history bibliography perhaps built around user contributions, something like Richard Jones's garbage collection bibliography https://www.cs.kent.ac.uk/people/staff/rej/gcbib/ .

When writing a book, you can't make everybody happy. I wrote this for a somewhat general techie audience and already had debates about the amount of math material in the lead-up to LISP I :-). Especially here on HN, there's a better-than-average chance that people will want more, something more encyclopedic, and I get that but "ok for a cross-section of Lisp history" already fills a book, I had to stop somewhere. Too much for some, not enough for others, hopefully "mostly ok" for most readers, it's all I can aim for.

And +1 on a comprehensive Lisp history bibliography, that's a great idea.

throwaway81523 2 hours ago
> When writing a book, you can't make everybody happy.

The usual reason a reader might be unhappy is that something they wanted to see isn't there. So the solution is put in as much as you possibly can ;). Maybe future editions can be bigger and more comprehensive. OTOH there seems to be quite a lot of what amounts to implementation tutorials. Maybe that's not needed in a history book. In a history book I'm more interested in sources than narrative. Although, some interviews with important Lispers would also be cool.

I can understand not wanting to put in too much math and theory and that's fine. I can't really tell what is there and what isn't beyond getting some hints from the bibliography entries.

This (by McCarthy) showed up immediately when I searched for something unrelated, some articles by Jeff Barnett about Lisp 2: http://jmc.stanford.edu/articles/lisp/lisp.pdf

This is a link dump about Lisp 2: https://softwarepreservation.computerhistory.org/LISP/lisp2_...

I have been wanting to look into Lisp 2 because it had supposedly had an interesting trick in its GC. It was a compacting mark/sweep GC but had an antecedent of generational GC where it usually wouldn't bother trying to reclaim memory that had already survived compaction once. I've been interested in re-implementing that trick in some modern implementations for small MCUs.

Chapter 8 sample pdf has a typo(?) in the first paragraph. Carl Hewitt's last name is spelled both Hewitt and "Hewitz", maybe even in the same sentence.

Using an accumulation parameter with tail recursion was per Wikipedia introduced in one of the LTU papers, sometime before Scheme. So the description in the chapter is at best imprecise. But, I would want to look further back historically to see whether any Algol compilers used the technique.

Overall the book looks readable as an intro to Lisp and Lisp implementation, but in a history book I'd like to see more precision and depth, careful citations, etc.

Darn, I had his name wrong and fixed it, but somewhere an undo button must have been hit. Thanks for pointing it out.

I'm more than happy to add corrections to an already "longer than zero" list of errata. I'll give the Scheme chapter and Wikipedia a once-over to see where I went off the rails.

throwaway81523 31 minutes ago
There's also an issue where Hewitt's actors were more like Erlang processes, i.e. unlike Scheme closures, they could run independently of each other. Maybe call/cc can simulate something like that. I remember the footnote in SICP claiming that Scheme was developed partly to understand what Hewitt was talking about, but I think that might not have been serious. It could be worth trying to talk to Steele or Sussman about this history.

Thank you, looks great!

Have you seen Behind the Parentheses, by Mark Jones Lorenzo? It goes into quite a lot of technical details about how things like eval/apply were implemented for example, and the larger academic and business contexts eg FORTRAN and earlier language development.

I’m a Lisp newbie (and mostly here for the Emacs Lisp) so a fair amount was beyond me, but I still found it quite readable and interesting.

Sounds very cool. I've dabbled with Lisp on and off since the mid-80's, starting with a text adventure in LISP-80 on a Kaypro 4, and though I've never written a serious project in Lisp I've learned a great deal from it. (Wrote a lot of TCL code once upon a time; I've always thought of TCL as a Lisp in which you do a lot of things backwards.)

what's the print like on amazon ones (.de)? I ordered two books once from lulu and woved never to do that again. Print was unreadable, and I'm not _that_ picky. They blamed it on the authors prep and offered a refund though. I was so mad, and still am that it turned me away from them completely though, unless someone tells me they worked at least some QA in their process.
cdegroot 5 hours ago
I would expect it to be good - it's typeset with LaTeX and shipped as a regular (vector) PDF, the rest is on Lulu/Amazon but I don't expect issues there. To be completely honest, I'm still waiting for the author copy from Lulu, which I'm using as a final check before allowing wider distribution (channels that don't allow quick fixes). But I've ordered several books from Lulu in the past, and they were fine, to my (amateur) eyes looked the same as something from a regular publisher (the modern ones likely use the same/similar print-on-demand hardware).

This is a nice and unexpected release, thanks for writing it. Getting a RPG endorsement is great. I just finished reading his foreword and skimming the table of contents and bibliography from the preview. I'd have liked to see a sample of a middle chapter to really see how technical and deep it gets (e.g. Land of Lisp gives its chapter 8 as a sample which I think is very representative for that book). But I plan to get this book regardless -- just not right now.

The back blurb hints that expert systems might be mentioned, but how much? No one ever seems to go much into their implementation or usage.[0] It also mentions writing some JS, which I guess is part of chapter 5, I wonder if that was a publisher request. (My favorite take on that subject in recent years is https://github.com/jart/sectorlisp)

Would it be fair to say this is mainly a history told through the lens of AI and PL research?

Amusingly I think part of me is already setting myself up for some disappointment -- it seems too short with too few references! But it's good to have a Lisp history book like this looks to be and I'm sure I'll learn things from it, and the promise of more RPG writings inside is enticing. Besides, any complete telling would take multiple books. (There's so much of historical interest locked up in proprietary applications and companies with their own histories, and so many papers published, there's also so much that can be dug through in the standardization mailing list (and other lists, like emacs) archives[1], the SAIL archives[2], the Xerox PARC archives[3], the CMU archives[4], and the many undigitized things sitting in boxes at the computer history museum...[5])

[0] Norvig's PAIP gives a small taste, one of the files: https://github.com/norvig/paip-lisp/blob/main/lisp/mycin-r.l... And a book about a particular system, MYCIN: https://www.shortliffe.net/Buchanan-Shortliffe-1984/MYCIN%20... And a short video: https://youtube.com/watch?v=a65uwr_O7mM

[5] Even in the earliest Lisp reports like https://www.researchgate.net/publication/42766480_Artificial... there are interesting things mentioned like a two-move checkmate program or "Other projects on which work continues include the Advice Taker, visual pattern recognition, and an artificial hand." Multiple times I've tried to track down those sorts of things mentioned in really old papers only to hit dead-ends on so many of them. Sometimes things were embellished, or were abandoned, or were just lost to time, and sometimes there's an undigitized box at the museum that might contain printouts etc. (There might be MYCIN source code, even.)

cdegroot 8 hours ago
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.

"arguably the most powerful programming language in the history of computing"

That can be said about quite a few languages, Forth included. The most powerful != easy to use and/or comprehend.

cdegroot 8 hours ago
That's why I said "arguably", of course.

But, to be honest: Forth is great, but... well... there's no "easy mode" Forth. Whereas there is "easy mode" Scheme - even SICP starts with a very simple and gentle up ramp - so I'd argue to give the honours to Lisp (I'm putting Smalltalk in second place). But that's my personal opinion, I get to put it on my book cover, that's all :-)
