There is relatively little literature on racism within the profession of academic librarianship. To investigate academic librarians' experiences of racism, this research project uses the framework of racial microaggressions, which are subtle, denigrating messages directed toward people of color. According to the results of an online survey, some librarians of color have had racial microaggressions directed at them by their colleagues. Non-minority librarians, however, are unlikely to recognize these disparaging exchanges.
