New & Secondhand — Relating to Radio and Television
When Broadcasting House, London entered service in 1932 the BBC published a book of photographs of the building called "Broadcasting House". Its pictures give us not only a view of the studios and other technical areas but also of many other parts of the building. A corridor, a staircase, a dressing room, the boiler room and the ventilation plant were all considered worth recording just as much as the Control Room, the Concert Hall or the Chapel Studio (3E).
In addition to this volume, a further book ("A Technical Description of Broadcasting House") detailed various technical aspects of the new building. From this we can attempt to work out just how the broadcasting system worked from microphones to the lines to the transmitters.
These books can still be found in second-hand bookshops and are well worth seeking out, though the technical one can be hard to find. So this site is an attempt to make their content more easily accessible. In these web pages you can find most of the photos from the books (hopefully out of copyright!).
