The Mathematical Theory of Communication

The content is certainly very conceptual but it provides a different view of what information is. In this world where content is king, it will refresh your notion of syntax and semantics, and the difference between just words and the information that lies within them.

Even if it is quite small, it's not the book you'll read from the beginning to the end without a stop. It is very deep and has profound implications on everyday's computer scientist's life. I've read once that often the size of a book is inversely proportional to its informational content...it is true for this one at least...

Where it all began.---The book grew out from an epic scientific paper in 1948, but luckly its author Shannon chose a light touch and a gentle delivery in his presentation. The paper became a book, with a 1949 first edition, which is now a classic, and which has been reprinted a number of times since, ending with the present lovely 1998 edition. It is still the place where readers can learn the essentials, including the two equations of information theory, that are now named after Claude Shannon.


Arguably, the most important paper EVER written!   February 14, 2002

I think it is fair to say that this book, based on Shannons landmark paper represents what I believe to be, the most important engineering paper ever written in the history of the world (both up to this point, and likely will remain so in the future). In terms of "practical implementation" of theory, it's fair to say that this seminal work has had a far greater contribution to mankind than Einsteins' paper on general and special relativity (just don't say that to a physicists face).

... All to often, famous theorists are relegated to "cult-like" obscurity. Persons like Shannon, Gallager, Forney, Komolgorov may be legendary within a cult-circle of die-hard communication theorists, but are relegated to unfortunate obscurity by the masses. It's rather unfortunate, with todays advanced communication systems, and techniques of coding (Turbo codes, modified LDPC codes, etc..)which push the boundaries to the ultimate limits as defined by Shannon.... that more people (both engineers, and laymen alike) don't recognize the names of early pioneers who started the revolution, and who's theories are the basis for many of our modern luxuries which allow us to download information at such rapid rates.

People often underestimate the deepness of Shannons' work,due to Shannon's writing style. He was one of those rare writers (somewhat like Forney, or Massey) who can actually explain complicated subjects using mere words, without the need for prettying the theory up with fancy math. Comparing the equation filled textbooks of today, versus Shannon's work, one might get the impression that Shannon's work was simplistic. I think it's clear to anyone whos studied his work, that IT WAS NOT SIMPLISTIC. Obviously, there was alot of "behind the scenes" math which Shannon had to go through to actually codify his many theorems. Just because Shannon did not show extensive derivations for each one of his theorems does not mean that he was not a good mathemetician..It merely means that he did not want to write a 1,000 page paper... he wanted to keep it simple (as was the customary writing style in the early to mid 1900's).

In short.. This book should be on YOUR shelf if you dont already own it, and if you are interested in information theory, and the deeper underpinnings of digital communications. I give the book 5 stars, not because it's any kind of elegant literary masterpiece; simply because it is based on the most important paper ever written. ... S.A. Hoffman -

This book is the best technical book i've ever read. It's clear, concise and logic. It explains all the fundamentals of communication theory, a basic for telecom and electronic engineers. All technical universities of everywhere must explain their communication theory subject following exactly this text. Above any other technical book. A gem.

Typically, a paper which defines a new field of science is not the best introduction to new researchers in the field. This is not the case with The Mathematical Theory of Communication. If you are interested in information theory, this is the one and only place to start.
