The Bell System Technical Journal was a periodical publication by the American Telephone and Telegraph Company (AT&T) in New York devoted to the scientific and engineering aspects of electrical communication. It was published under this name from 1922 until 1983, when the breakup of the Bell System placed various parts of the system into separate companies.
After the restructuring of the Bell Laboratories in 1984, the Bell System Technical Journal was renamed to AT&T Bell Laboratories Technical Journal. From 1985 to 1996 it was published under the title AT&T Technical Journal.
The Bell System Technical Journal was published by AT&T in New York City through its Information Department, in behalf of Western Electric Company and the Associated Companies of the Bell System. The first issue was released in July 1922, under the editorship of R.W. King and an eight-member editorial board. From 1922 to 1951, the publication schedule was quarterly. It was bimonthly until 1964, and finally produced ten monthly issues per year until the end of 1983, combining the four summer months into two issues in May and July.
Publication of the journal under the name Bell System Technical Journal ended with Volume 62 by the end of 1983, because of the divestiture of AT&T. Under new organization, publication continued as AT&T Bell Laboratories Technical Journal in 1984 with Volume 63, maintaining the volume sequence numbers established since 1922. In 1985, Bell Laboratories was removed from the title to AT&T Technical Journal until 1995 (Volume 74).
In 1996, the title was changed to Bell Labs Technical Journal, and publication management was transferred to Wiley Periodicals, Inc., establishing a new volume sequence (Volume 1).
- In 1928, Clinton Joseph Davisson published a paper on electron diffraction by nickel crystal, thus unambiguously establishing the wave nature of electron. This discovery led to a widespread acceptance of particle-wave duality of matter and won him the 1937 Nobel Prize in Physics.
- Claude Shannon's paper "A Mathematical Theory of Communication", which founded the field of information theory, was published as two-part article in July and October issue of 1948.
- Many landmark papers from the developers of Unix appeared in a themed issue in 1978.
- The journal is notorious for numerous articles disclosing the internal operation of the long-distance switching system used in direct distance dialing (DDD) in the Bell System in the 1950s and 1960s. Articles such as those by A.Weaver and N.A. Newel (In-Band Single-Frequency Signaling),, and by C. Breen and C.A. Dahlbom (Signaling Systems for Control of Telephone Switching) enabled phone phreaks to develop the blue box apparatus, which mimicked the switching system's signals to allow them to make free long-distance calls.
- The 2009 Nobel Prize physicists Willard Boyle and George E. Smith described their new charge-coupled device in the journal in a 1970 paper.
