Bell Laboratories Record (BLR) was a publication of the Bureau of Publication of the American Telephone and Telegraph Company (AT&T) and Bell Laboratories. It commenced distribution as a house organ for the employees and associates of the laboratories and the Bell System in September 1925, shortly after the founding of Bell Labs as a separate corporate entity. The first Director of Publication was John Mills, leading three managing and assisting editors, and an eleven-member editorial advisory board.
