This paper traces the published literature on whiteness in libraries, identifying major themes in that literature, and then highlights the importance of decentering whiteness for moving the information professions forward. Engaging a dialogic ethnographic methodology, this paper was borne of conversations between librarians of color who worked in the same predominantly white library. The salient themes from those dialogues were the many ways that adherence to whiteness in libraries has had deleterious affective and career implications for librarians of color. The authors argue that to decenter whiteness in libraries and other information centers, it is crucial to center the experiences and well-being of librarians of color; diversify the ranks of librarians through bold initiatives, significantly increasing the numbers of librarians of color; and make large-scale incisive structural change at organizational levels. The paper concludes with an invitation for all information professionals to participate in inclusiveness initiatives by moving from microaggressions to microaffections.
