The Infodad Web site (, which Dr. Estren created and which has been online since 1997, features reviews of books, music, software and hardware. The site is updated weekly, generally on Thursday mornings (Eastern time). Historical articles dating back to 2005 remain online. Access is free and available to all. The site's title is intended to be family-friendly (like the reviews) and is a slightly amusing semi-portmanteau word.
