Bell Systems Technical Journal online

on

AT&T Bell Labs has recently made their entire archive of the Bell Systems Technical Journal (BSTJ) available for free on-line. The collection goes all the way back to 1922. In fact, the first issue has an article on the transmission characteristics of the submarine cable. For example, in 1978 an entire issue of the journal was dedicated to a new operating system called Unix.

There are many other important and historic papers that originally appeared in BSTJ including a paper on the first semiconductor, Shannon’s work on Information Theory, and work on fiber optics.  This collection is an important contribution from one of the premier research organizations in the world in the 20th century.
