Academic debate is a collaborative mode of knowledge production, while prevailing academic norms steer scholars to labor in solitary isolation. The DAWG believes this disconnect may be one factor accounting for the difficulties spelled out at Sedalia and Quail Roost. A systematic, synergistic and rigorous approach to co-authorship may help bridge this disconnect. This committee's charge is to draft guidelines for co-authorship that will make explicit expectations and responsibilities for DAWG co-authors.
Here is a good first stop for extant guidelines, including citations on the 1991 JAMA article (state of the art in medicine) and the "Vancouver Group." The authorship form at the JAMA website has a good checklist that should spark some creativity.
