All told, I've written 176 books, including some that weren't published (but contracted and paid for) and various derivatives and multiple editions. When counted uniquely, the title list is shorter. I calculate only 68 unique titles, as presented here.

This list shows what I consider to be my fully unique titles. Second and additional editions are counted for each original title, as well as derivative works. Even if a second or third edition contains over 80 percent new material (which is typical for my work), I consider it a derivative to the original.

Edition numbers are sequential and may not match up with the book's title or edition number, which the publisher uses. Often published editions skip numbers or use a different scheme.
