Today's Technical Journal
From 1922 to 2020, the Bell Labs Technical Journal published peer-reviewed articles from researchers attempting to solve the big challenges in information and communications technology (ICT). Nokia is proud to partner with IEEE to provide access to the full Bell Labs Technical Journal archive.
The journal was first published in 1922 as The Bell System Technical Journal by AT&T's Information Department.
For its first 30 years of publication, the journal was released quarterly. The journal was devoted to the sciences and engineering disciplines needed to provide improvements to the Bell Telephone System. When Bell Labs underwent divestiture in the mid 1980s, the journal was renamed AT&T Bell Laboratories Technical Journal (1984), and then AT&T Technical Journal (1985–1996). Bell Labs breathed new life into the journal yet again by renaming it the Bell Labs Technical Journal (BLTJ) in 1996.
