Bell System Technical Journal was the in-house journal of Bell Laboratories.

It is most famous for Claude Shannon's paper A mathematical theory of communication which founded the field of information theory. Also important are the two Unix-themed issues that appeared in 1978 and 1984, containing many landmark papers from the system's developers.

The journal is also notorious for an article in the 1950s that revealed the internal operation of the long distance switching system. This article, entitled "In Band Signal Frequency Signalling," sparked phone phreaks to develop the Blue Box.

The journal has since been through several name changes including, AT&T Bell Laboratories Technical Journal and AT&T Technical Journal. It is currently known as Bell Labs Technical Journal.
