The picture presented by the network of co-authors in CEDRA studies looks similar to the previous one of co-participants in events (figure 9): again the hard core (co-authors involved in at least two studies) consisting nearly entirely of FORUM members. The potential of this densely connected group (figure B) for generating knowledge, in exchange with the wider group of authors, is very high. In contrast, the four co-authors most frequently involved (figure C) are connected with each other by just one person. This comparison (figures B:C) suggests that the collaboration in CEDRA publishing activities is underpinned by a relatively large group of closely related researchers rather than a small team.
