“…Subjective judgment also enters into questions of quantity and rate of publication because research into publication productivity in the field has heretofore been hampered by the constraints of available data sources, sources that generally have been limited to a select subset of the publications of the field, at best the relatively small number indexed in one or another edition of Index to Journals in Communication Studies Through 1995 (Matlon & Ortiz, 1997). As well, prior work has tended to focus on questions of the average productivity of all scholars in the field at all points in history (Hickson, Stacks, & Bodon, 1999), of the relative productivity of departments (Barker, Hall, Roach, & Underberg, 1981), or of the productivity of exceptional scholars (Hickson, Bodon, & Turner, 2004; Hickson, Stacks, & Amsbary, 1989).…”
