Use Practical Common Lisp [0] as the book to start learning Lisp, Common Lisp is the more production version lisp. Download LispWorks Personal Edition [1], if you want to start working with an IDE setup. Use it when working through PCL. LW also has GUI library, mobile runtimes and other libraries available from QuickLisp [2], CL's package manager to install various libraries. After working through PCL, you will have a good CL foundation. You can expand your macro (pun unintended) knowledge by working through [3]. Other good resources: PAIP and Land of Lisp. Note about PAIP is more a specific application of CL to solve classical AI Problems, despite that it is still counted as among the best programming books out there. Hope this helps and `Welcome to the Dark Side`. PS: Except `Land of Lisp` cited in the resources, everything is free.
