Five directory issues of the "Journal of Education for Librarianship" covering a span of 18 years were examined in order to determine whether there are gender-related differences in teaching specialties within graduate programs of library and information science. The results of this inquiry revealed strong support for the gender-linked nature of teaching specialties within the discipline. Specifically, women tend to specialize in the teaching of services for children and young adults, cataloging, and classification, where men have tended to specialize in information science, research methods, library automation, and the history of books, printing, and libraries. These patterns parallel those found in the courses selected by male and female students and in the career paths of M.L.S. degree graduates. The results are discussed in terms of their implications for library educators as sex-role models. (A list of references and notes is included.)
