This article reports the findings of a study exploring the nature and extent of research on diversity in library and information science (LIS) doctoral dissertations from 2000 to 2009. By systematically examining the last decade of dissertations in the field, this study is meant to reveal the levels of interest in diversity research among doctoral students in LIS and the types of diversity topics and contexts being addressed by scholars who will represent the next generation of LIS scholars and educators. The level of focus on diversity by the next generation of scholars will heavily shape the amount of support library research can provide library resources, programs, services, and outreach in supporting ever more diverse service populations. Examining these dissertations serves to: (1) determine whether scarcity of diversity-related research in publications is also evident in dissertation studies; (2) reveal areas of diversity that need more research focus to support practice as these new scholars add their voices to the LIS discourse; and (3) suggest future directions that diversity research may support library practice. The authors begin by discussing their definition of diversity in LIS, proceed to presenting the details of the study, and then conclude with the implication of the findings to practice.
