Fred Hutchinson Cancer Research Center is a biomedical research institution. Arnold Library is the main information hub for the research workforce. Medicine and biomedical research have a dark history of neglecting the needs of certain people, even mistreating or subjecting them to unethical practices to benefit the powerful. White, heterosexual, cis-males were long the primary concern, becoming the “normative” model. Arnold Library rejects that legacy by working to integrate DEI. The library is improving its collections and services, and I collaborated by auditing the book collection for DEI materials and writing a new DEI section in the collection management policy.
