In 2014, my father (Dr. Michael Connolly) and I published 8 articles on a website we set up called Open Peer Review Journal. The website is a new approach to open peer review where anybody can register and provide review comments on a given article. Articles are “living” and can be updated by the authors as new comments are made.
