Since 1996, Berwick has co-authored five books and two dozen substantive articles in various martial arts publications such as the Journal of Asian Martial arts ("JMA), Kung Fu Tai Chi (KFTC)", and "IKF". Much of the material focuses on relating core Taiji concepts and principles that were previously unavailable in English, or rarely seen at best. As such, three of his articles have been listed as select research references in Asian martial tradition by the Via Media Publishing Corporation (Publishers of the Journal of Asian Martial Arts).
