Good for you. Our field needs research, documentation and exchange about these methods which are growing worldwide. An invaluable resource is the free online International Bibliography of Psychodrama, which contains more than 6,000 entries including books, journals, papers and the like.
Started by James M. Sacks, it is the fruit of an attempt to compile an exhaustive list of citations of scientific works on psychodrama since its creation by J.L. Moreno. Errors, exclusions and incomplete information that should be corrected should be brought to the attention of Michael Wieser at michael.wieser@uni-klu.ac.at. You may send copies to Michael Wieser, Department of Psychology, Universitaetsstr 65, 9020 Klagenfurt, Austria, Europe. When submitting references, please use current standard American Psychological Association (2009) format if possible.
