A substantial portion of Karl Weick’s influence on organization studies is based upon his classic book The Social Psychology of Organizing (abbreviated as Organizing). A citation analysis shows the magnitude of this influence compared to five other organization studies classics, and reveals that Organizing continues to be highly cited. A citation context analysis (i.e. content analysis) of all citations to Weick (1979) in three top organization studies journals (Academy of Management Review, Administrative Science Quarterly, and Organization Studies) shows that 12 concepts account for 67.6% of citations to Organizing, but that the book is cited for a remarkable diversity of additional content as well. Furthermore, a consideration of differences between the concepts cited in the US journals versus Organization Studies reveals several regional differences. Finally, very few citations are critical of Organizing or involve empirical tests. These results hold a variety of implications for future research.
