COMMON LISP: An Interactive Approach by Stuart C. Shapiro.
From the preface:
Lisp is the language of choice for work in artificial intelligence and in symbolic algebra. It is also important in the study of programming languages, because, since its inception over thirty years ago, it has had full recursion, the conditional expression, the equivalence of program and data structure, its own evaluator available to the programmer, and extensibility—the syntactic indistinguishability of programmer-defined functions and “built-in” operators. It is also the paradigm of “functional,” or “applicative,” programming. Because of the varied interests in Lisp, I have tried to present it in a general and neutral setting, rather than specifically in the context of any of the special fields in which it is used.
Although published in 1992, this book remains quite relevant today. How many languages can you name that have with equivalence of program and data structure? Yes, that’s what I thought.
