I was a full-time teacher in the philosophy department at Sacramento City College from 1977 until my retirement in 2007.
I started The Skeptic's Dictionary website (www.skepdic.com) in 1994. It has grown from a few dozen to over 700 entries.
"The Skeptic's Dictionary" was published in August 2003 by John Wiley & Sons.
My textbook "Becoming a Critical Thinker" was published by Pearson in 2000. A second edition was published in 2005.
"Unnatural Acts: Critical Thinking, Skepticism, and Science Exposed!" is an introduction to critical thinking aimed at a general audience.
"Mysteries and Science: Exploring Aliens, Ghosts, Monsters, the End of the World and Other Weird Things" grew out of a project called "A Skeptic's Dictionary for Kids."
I'm currently working on a book on biases, illusions, and fallacies...and how to overcome them.
