Beyond Contact: A Guide to SETI and Communicating

A Guide to SETI and Communicating with Alien Civilizations

By Brian McConnell

First Edition March 2001
ISBN: 0-596-00037-5
432 pages

In Beyond Contact: A Guide to SETI and Communicating with Alien
Civilizations, author Brian McConnell examines the science and technology
behind the search for intelligent life in space, from the physics of
inter-stellar laser and radio communication to information theory and
linguistics. If you've ever wondered whether it really would be possible to
communicate with other civilizations, you'll want to read this book.
