Claude E. Shannon - Collected Works on Information Theory (5 books)

* Claude E. Shannon - Collected Works on Information Theory (5 books)

CLAUDE E. SHANNON (1916–2001) was an American mathematician, electrical engineer, and cryptographer widely regarded as the “father of information theory.” His work laid the mathematical foundation for the digital age, influencing everything from telecommunications and computer science to cryptography and artificial intelligence. By rigorously defining the concept of information and establishing limits on signal transmission and compression, Shannon transformed communication engineering from an empirical field into a precise mathematical discipline.

His master’s thesis at MIT, "A Symbolic Analysis of Relay and Switching Circuits" (1937), demonstrated that electrical applications of Boolean algebra could construct any logical numerical relationship, thereby establishing the theory behind digital computing and digital circuit design. Shannon’s most celebrated paper, "A Mathematical Theory of Communication" (1948), laid the foundations for the field of information theory. In this groundbreaking study, he introduced the concept of the “bit” as a fundamental unit of information and developed the notion of information entropy to measure uncertainty in messages. Advancements across multiple scientific disciplines utilized Shannon's theory—including the invention of the compact disc, the development of the Internet, the commercialization of mobile telephony, and the understanding of black holes.

In addition to information theory and circuit design, Shannon made significant contributions to cryptography and artificial intelligence. During World War II, he worked on secure communications and later published "Communication Theory of Secrecy Systems" (1949), which is now considered one of the foundational pieces of modern cryptography. He also explored machine intelligence and game theory, building mechanical devices that could solve mazes or play chess. Across these diverse achievements, Shannon consistently demonstrated a rare blend of mathematical rigor, engineering practicality, and playful creativity—qualities that cemented his legacy as one of the most influential scientists of the twentieth century.

The COLLECTED PAPERS contains all of Shannon's published works, as well as many that have never before been published. The published papers include all his classic papers on information theory and switching theory. Among the unpublished works are his once-secret war-time reports, his Ph.D thesis on population genetics, unpublished Bell Labs memoranda, and a paper on the theory of juggling.

The supplementary volume, entitled MISCELLANEOUS WRITINGS (2013), contains unpublished or lesser-known technical manuscripts, Bell Labs memoranda, technical reports, lecture notes, and miscellaneous typescripts that did not appear in the Collected Papers. The editors scanned these documents, "put [them] into a binder held together by an Acco metal strip", and donated the resulting PDF to several libraries and "one or two other places". The original scan is poor and difficult to OCR or improve upon. Beyond adding bookmarks for ease of navigation, I include the unprocessed PDF here.
