The ANSI Common Lisp Reference Book

* Every Common Lisp operator, variable, etc. is described with usage examples.* Related topics are linked (so alternative solutions can be considered).* Common features of different operators will typically be described specially. This indicates to users that they need only learn a feature once to use it in any context.* Short descriptions are provided so the relevance of a particular page can be quickly determined.* Special essays on general topics provide introductions to aspects of the Common Lisp language that the reader may not be familiar with.* An up-to-date reference manual designed for programmers actually using the Lisp language
