History of the British Inter-Services Security Board and the Allocation of Code-Names in the Second World War

AbstractDuring the Second World War there was an increasingly developed system for controlling the code-names used for operations where different Allied forces were involved. This paper follows the development of this system – based on the British Inter-Services Security Board – that spread to overseas theatres on the British side and to American forces world-wide. The selection of code-names was not without controversy; with Winston Churchill getting personally involved and his intervention is highlighted. A critique of the system is attempted, although the final judge is ultimately the success of the security of the activities disguised by the code-names.

After developing an interest in tracking down operational code-names in World War II, he produced a substantial bibliographic listing for his Fellowship of the Library Association (now Chartered Institute for Librarians and Information Professions – CILIP). It was from the covering preamble to that bibliography that developed into research into the organization and structure of the allocation of those same code-names.
