Seibel, a programmer, covers syntax and semantics of Common Lisp and shows how to write software in this guide for programmers and students. Early chapters cover the language itself, and later practical chapters help readers write programs for filtering spam, parsing binary fields, cataloging MP3s, streaming MP3s over a network, and providing a Web interface for the MP3 catalog and server.
