Download the LaTeX source code (with figures and a Makefile) in a zip file or a gzipped tar file.

You can read the preface of the book in HTML.

The fourth edition is tailored to help students prepare for the Computer Science AP Exam. I have made some changes and added new material to improve the coverage of the AP syllabus (without bloating the book too much!). I have also incorporated many of the exercises I use in my classes into the book.
