From "An Introduction to the Theory of Numbers", by Niven, Zuckerman, and 
Montgomery, Fifth Edition, 1991:

        An integer p > 1 is called a prime number, or a prime, in case there is 
no divisor d of p satisfying 1 < d < p.

Knuth, Vol. 2, Third Edition, implicitly says that 1 is not a prime.
