If you get stuck, find an online community and ask smart questions.

Lisp Environments

Prepackaged environments
- Portacle - A portable and multiplatform Common Lisp environment. It ships a slightly customized Emacs with SLIME, SBCL (a popular Common Lisp implementation), Quicklisp and Git. No installation needed, so it's a very quick and easy way to get going.
- Lispbox - An IDE (Emacs + SLIME), Common Lisp implementation (Clozure Common Lisp) and library manager (Quicklisp), pre-packaged as archives for Windows, macOS and Linux. Descendant of "Lisp in a Box" mentioned in Practical Common Lisp.
- Lispworks Personal Edition - A non-Emacs based IDE for LispWorks Lisp, with some restrictions.
- Allegro Common Lisp - Has a free Express Edition IDE, and training videos on YouTube.

For advanced users
- Articulate Common Lisp - A HOWTO for putting together a Lisp environment, and has information on useful libraries and how to structure projects.
- If you're an experienced Emacs user, you can just install SLIME and a supported Common Lisp implementation. See the SLIME manual for more details.
- The Common Lisp Cookbook has more information about installing an implementation using an implementation manager like Roswell (⭐1.7k), or on Docker.

Online References

The Common Lisp Hyperspec (CLHS) - The language reference document for Common Lisp. Bookmark it now.
- Chapter 7 - Covers the Common Lisp Object System (CLOS).

The ANSI Common Lisp Standard Draft - The last draft version of the ANSI INCITS 226-1994 (previously ANSI X3.226-1994) standard.
- The draft is free, the standard isn't.
- It's pretty much the same as the official standard, and some people prefer it to the CLHS.

The Common Lisp Cookbook - A list of useful Lisp recipes. Also contains a list of other online sources of CL information.

Common Lisp the Language (2nd Edition) by Guy L. Steele - A description of the Common Lisp language from just before it was standardized by ANSI. Don't use it as a reference.
- Cliki on CLtL2 - Claims it has more useful descriptions of LOOP and FORMAT than the CLHS does.
- Stack Overflow on CLtL2 - Some recommend using CLtL2 for insight and inspiration, but to use the CLHS when programming.
- A list of differences between CLtL2 and the ANSI Common Lisp specification.
- Chapter 28 - Covers the Common Lisp Object System.

Online Books

Common Lisp: A Gentle Introduction to Symbolic Computation by David S. Touretzky - a good introduction for people new to programming. Contains code for really useful utilities like DTRACE and SDRAW.

Common Lisp: An interactive approach by Stuart C. Shapiro - A textbook that teaches mainly through the use of exercises.

Practical Common Lisp by Peter Seibel - A great introduction for experienced programmers, and tries to highlight from the very beginning what makes CL different to other languages.

Common Lisp Koans (⭐3k) - Not exactly a book, but a set of koans to help you learn the language.

On Lisp by Paul Graham - A great book for intermediately experienced Lispers.

Let Over Lambda by Doug Hoyte - An advanced book on Lisp Macros.
- The first six chapters are available online.
- Comments on Let Over Lambda - Several people recommend that you be comfortable with On Lisp before reading this book, and that the start is slow.
- The chapter on closures - Has several non-trivial examples, and demonstrates the power of this feature.

Paradigms of Artificial Intelligence Programming by Peter Norvig (⭐6.9k) - Has many interesting applications of Lisp, but is no longer a good reference for AI.

Offline Books

Land of Lisp by Conrad Barski, MD - A fun introduction to Lisp that uses comics and has you writing games.
- Available as an ebook.
- A couple of the LOOP macros are written for x for y... which you can change to for x from 0 for y... to make them work in SBCL.
- Has an errata page.
- Most of the book is entertaining and fairly easy, but gets hairy from about Chapter 18. It doesn't feel like later chapters introduce much, so I recommend switching to a different book at that point.
- The Web server example in Ch 13, 19 and 20 will only work on CLISP, and needs the addition of HTTP response headers to render the HTML properly.

ANSI Common Lisp by Paul Graham - Good as a reference, covers CLOS, and has several example program implementations.
- Plaintext versions of Chapter 1 and Chapter 2 are available online.

Common Lisp Recipes by Edmund Weitz - A great set of Common Lisp patterns.

Object-Oriented Programming in Common Lisp by Sonya E. Keene - An in-depth description of the CLOS, and shows how to use it with example applications.

The Art of the Metaobject Protocol by Gregor Kiczales, Jim des Rivieres, and Daniel G. Bobrow - Describes the CLOS Metaobject Protocol (MOP).
- Chapters 5 and 6 (available online) - The specification of a metaobject protocol extension to CLOS, by Robert Strandh.
  - Superseded by the modern public domain CLOS MOP specification by Jean-Philippe Paradis (Hexstream).
- Adam Tornhill on AMOP - Recommends reading Practical Common Lisp, then Object-Oriented Programming in Common Lisp, and then AMOP.
