(1975 – 1984)
This section of our web-site includes digitised versions of all the papers published in the journal Dynamica, the precursor to the Society’s journal System Dynamics Review. At an informal meeting at the 2005 Boston conference of the ‘three presidents’ (Immediate Past President, President Elect, and myself as the then serving President), it was recognised that Dynamica comprised an important repository of early System Dynamics papers. Most people know someone who knows someone with a set of issues, and copies of all issues were lodged with the British libraries of record, but it was decided that all Society members and researchers in the field should be able to access easily the full set. That facility is now in place, and goes a long way to completing the ‘digital paper trail’ of System Dynamics research and publication.
Dynamica essentially started as a house journal for the System Dynamics Group at Bradford University, initially publishing work by Bradford people, visitors to the group, research collaborators and other professional acquaintances, but soon started attracting submissions from people outside this network. This demonstrated the need for a dedicated, open access journal, which Dynamica quickly became. It was a critical move that it should morph into the System Dynamics Review as the official journal of the Society when it was formed in the 1980s.
In its time, Dynamica published a number of important papers and eventually was taken by quite a wide international subscribership; it is important and timely that these are now available in their full, original versions to all researchers and practitioners.
It is very important that we acknowledge the contribution of the editors and supporters who worked to develop the original journal, to the University of Bradford for encouraging and underwriting the venture. It is equally important that we appreciate all those who have volunteered much of time to the digitization project. Finally, we must be grateful to the University of Bradford, as a copyright holder, for the generosity in permitting us to make access to this valuable literature base freely available through our website.

What you find is historically interesting – but also more than that. Naming no names, I was surprised to find ideas discussed that I had always thought originated in later publications. So these papers are worth getting for those (and it should be all of us) interested in correctly recording the provenance of ideas; Dynamica is worth checking for those ‘first mentions’. More than that, the papers contain some very interesting work that deserves re-visiting and talking forward. There are excellent research ideas that deserve to be taken forward.
