I've read most of it, and I think it's a great book for experienced developers looking to dive deep into a pretty specific range of topics. As a beginner's second book after SICP, I'd still recommend it, because it assumes almost nothing. Having read it, I find it hard to see it as just a collection of intros, because you get a lot of mental algorithmic mileage out of e.g. hand-rolling an implementation of automatic differentiation, which is done in the book. You get a lot of clarity on things that are still quite useful.

But does the book dive deep enough? Won't be more useful to go with more specialized books/papers?

Peter goes through various iterations improving the approaches in the book. There is a bunch of stuff - like writing good and efficient Lisp code - which is not covered that well in many other books.

Forgot to mention - for the person who is not (that much) interested in Lisp (anymore).
