“…When an individual publication is being analysed, a classification scheme may be designed that is specific to that publication: examples of this approach include studies of books on software engineering (McCain and Salvucci, 2006) and on strategic management (Anderson, 2006) and of articles on molecular biology (Ahmed et al, 2004;McCain and Turner, 1989), organizational theory (Anderson and Sun, 2010;Lounsbury and Carberry, 2005;Mizruchi and Fein, 1999) and neuropharmacology and the sociology of science (Cozzens, 1985). Other classification schemes have been developed for analyzing citations to the works of an individual author (Brittain, 2000) and to an individual journal (Spiegel-Rosing, 1977) or, most commonly, for use across the whole range of subjects and types of publication (Bonzi and Snyder, 1991;Cano, 1989;Case and Higgins, 2000;Chubin and Moitra, 1975;Meho and Sonnenwald, 2000;Moravesik and Murugesan, 1975;Oppenheim and Renn, 1978;Peritz, 1983;Shadish et al, 1995;Vinkler, 1987).…”
