We Are Not Alone
We Are Not Alone is an authoritative and best-selling account of the search for extraterrestrial life and intelligence by Walter Sullivan, science editor of the New York Times.1 First published in 1964, it was destined to become an early SETI classic, alongside Sagan and Shklovskii's more technical Intelligent Life in the Universe.
