A study examined the contents of 18 public relations textbooks published between 1991-1997 to determine the quality of minority inclusion. Results indicated that, of the 8,071 pages examined, 97 pages included minorities. Findings suggest that the results of this study were not significantly different from those of a similar, earlier study of public relations textbooks published between 1979-1988. Textbooks should include information about different ethnic groups because they act as socializing agents for students not exposed to cultural diversity, and students would get a more accurate depiction of the environment within which their public relations strategies and tactics would take place. Further research is recommended to assess whether a textbook that excludes discussion of minorities adequately provides students with the insight and information necessary to design and implement public relations campaigns in a heterogeneous society.
