I work as both a writer and a computer programmer. Most of my books have been college computer textbooks including New Perspectives on Computer Concepts, The Practical PC, Practical Computer Literacy, Practical Office 2007, and many more. (For a fairly complete list, search for "Parsons Oja" at Amazon.com.)

I recently published Ordinary Heroes: Six Stars in the Window, my first non-fiction historical book, which is a available in print and in several innovative digital formats where photos come to life as video.
