We are currently developing ITAA literature, with a few in-progress resources currently available:
While we continue to write literature, we also encourage those suffering from internet and technology addiction to read other 12-step literature and discuss it with their fellow ITAA members.
The big book of AA
The Twelve Steps and Twelve Traditions of AA
The Twelve Steps and Twelve Traditions of Overeaters Anonymous
The Twelve-Step Workbook of Overeaters Anonymous
Overeaters Anonymous The Steps Made Simple
AA is a great fountainhead for 12 step wisdom, and OA is a useful reference as a program in which complete abstinence (in their case, from food) is not possible. NA, ACA, SA, CoDA, and CLA are also valuable references.
