Do archivists `curate' history? And to what extent are our librarians the gatekeepers of knowledge? Libraries and archives have a long and rich history of compiling `radical collections'- from Klanwatch Project in the States to the R. D. Laing Archive in Glasgow- but a re-examination of the information professions and all aspects of managing those collections is long overdue. This book is the result of a critical conference held at Senate House Library in 2017. The conference provided a space to debate the issues and ethics of collection development, management and promotion. This book brings together some key papers from those proceedings. It shines a light on pressing topical issues within library and information services (LIS)- to encompass selection, appraisal and accession, through to organisation and classification, and including promotion and use. Will libraries survive as victims of neoliberal marketization? Do we have a responsibility to collect and document `white hate' in the era of Trump? And how can a predominantly white (96.7%) LIS workforce effectively collect and tell POC histories?
