Bell System Technical Journal at the Internet Archive
The Bell System Tech Journal has moved around to a number of different free and pay-walled sites over the years. I'm glad to see it is now on the Internet Archive . A number of seminal papers were published there. Here are some of my favorites. Shannon's Mathematical Theory of Communications, published in two parts. This is arguably the most influential scientific work of the 20th century. Bell System Technical Journal, 27: 3. July 1948 pp 379-423. A Mathematical Theory of Communication. (Shannon, C.E.) Bell System Technical Journal, 27: 4 October 1948 pp 623-656. A Mathematical Theory of Communication (Shannon, C.E.) Pierce's "less mathematical" book on Shannon's work is also on the Internet Archive. It was the textbook for Bob Krull's course on Info Theory that I took at RPI in 1976, which has had a deep influence on my thinking. An Introduction to Information Theory Symbols, Signal and Noise by John R. Pierce
