The Big List and the Psychotherapy List are the primary results of this investigation into the history of researched TA articles. They are found in Annexes 1 and 2 respectively, which are included as separate documents from the main documnet (Scientific evidence base for transactional analysis in the year 2010) for ease of later reference. Both lists contain comments by the author. The comments are offered only to pass on the author’s limited knowledge of the studies, and the author makes no claims of having made full and systematic reviews of the articles in the lists.
