Who constructs, controls, and preserves the Official Record is key to documenting and understanding events. However, because of the potential of the Official Record to contain evidence of controversial policies and malfeasance, its construction, control and preservation in the arena of national security is inherently contested. This book interrogates the boundaries between national security, accountability, oversight and the Official Record in the context of democratic states. Using historical case studies to explore the relationship between government record-keeping and accountability, The Official Record interrogates the tension between openness and secrecy in policy. It defines and explores the concept of the Official Record in democracies, and evaluates different methods of democratic oversight through the lens of the Official Record. With case studies from the UK, US and Canada, the volume is designed to help readers explore the Official Record in the context of the national security operations of democratic states. Chapters are research-based pieces of original writing that feature a Document Appendix containing primary documents, often excerpts, that are key to their narrative. Engaging with a broad range of primary material, this book interrogates the boundaries between national security, accountability, oversight, and the Official Record.
