Bell Labs Technical Journal

The Bell Labs Technical Journal was the in-house scientific journal for scientists of Bell Labs, published yearly by the IEEE society. The journal was originally established as the Bell System Technical Journal (BSTJ) in New York by the American Telephone and Telegraph Company (AT&T) in 1922. It was published under this name until 1983, when the breakup of the Bell System placed various parts of the companies in the system into independent corporate entities. The journal was devoted to the scientific fields and engineering disciplines practiced in the Bell System for improvements in the wide field of electrical communication. After the restructuring of Bell Labs in 1984, the journal was renamed to AT&T Bell Laboratories Technical Journal. In 1985, it was published as the AT&T Technical Journal until 1996, when it was renamed to Bell Labs Technical Journal. The journal was discontinued in 2020. The last managing editor was Charles Bahr. ()
