Book excerpt: The first introduction to writing about intelligence and intelligence services. Secrecy has never stopped people from writing about intelligence. From memoirs and academic texts to conspiracy-laden exposes and spy novels, writing on intelligence abounds. Now, this new account uncovers intelligence historiography's hugely important role in shaping popular understandings and the social memory of intelligence. In this first introduction to these official and unofficial histories, a range of leading contributors narrate and interpret the development of intelligence studies as a discipline. Each chapter showcases new archival material, looking at a particular book or series of books and considering issues of production, censorship, representation and reception.
