The Cambridge Extra Mural Board, which celebrated its centenary in 1973, was the first extra-mural department in any university, and is important both as a pioneer, much copied elsewhere, and because it was instrumental in the founding of other kinds of institution, including university colleges. Dr Welch has written a detailed history of the board and its predecessor, the Local Lectures Syndicate, based primarily on the archive material at Stuart House, Cambridge. The book will interest social and educational historians and those actively concerned with adult education.
