Published this month and edited by two esteemed archivists, Michael Moss and David Thomas, Archival Silences contains a chapter on diaries and silence by GDP’s founding director: Polly North. https://www.taylorfrancis.com/chapters/edit/10.4324/9781003003618-12/diaries-silence-polly-north. The chapter is a celebration of the diaries at the Great Diary Project at Bishopsgate Institute and of the rich ambiguities almost all diaries speak of.
