It's new for those who haven't read it. ;-)

There are a bunch of oldish Lisp books, but which might be read with some benefit even today. I'd would for example mention Performance and Evaluation of Lisp Systems (benchmarking Lisp), Keene's CLOS book, PAIP (writing classical non-trivial code and optimizing it), AMOP (meta-objects, extensible architecture), On Lisp (macros), Land of Lisp (fun&games), Common Lisp Recipes (Lisp lore), ... and also the Lisp Machine Manual ...

For a bunch of, often old, Lisp related books see my list: https://www.librarything.com/catalog/lispm&tag=lisp

In general, Lisp books were generally so far ahead of the state of the art at the time they were written, they remain very relevant and timely today.

And very likely tomorrow. :)

Any halfway good language has a constant procession of new books being cranked out about it. Reading a new "bible" is required every 3 to 5 years, along with updates to your entire code base.

Common Lisp Recipes by Edi Weitz is the most recent 'bible'. Another excellent book.

I strongly agree and I can't recommend it enough. It's not a good first book, though - it's not meant as an introduction to Common Lisp (for that it, in fact, recommends Practical Common Lisp). It's best read if you can already find your way around Common Lisp REPL, and write some basic programs - it systematizes the knowledge, explores various quirks of the language, and shows you practical solutions to common problems.

As for introduction, another nice book is Land of Lisp - it introduces you to most of Common Lisp by means of writing games of increasing complexity.

Has anything really changed, though? QuickLisp, I guess, but that feels like about it.

Also Lisp in a Box is no longer available. Nevertheless this book is always on my desk. I refer to it almost on a weekly basis.

It has been superseded by Portacle.

I was going to mention ASDF but, from its changelog, it looks like its first release was in 2001(!).
