Fine, look at Mathworld, probably the best and most accurate math resource on the internet. Here's the article on what a repeating decimal is (with several citations from mathematical books and journals):

This page clearly states that repeating decimal notation, such as 0.333... represents a NUMBER, not a series. Otherwise how could you write 1/3 = 0.333... if one is a number and the other is a series? The article does not even use the word series; and lastly for great effect, allow me to quote the opening line of the article:

A repeating decimal, also called a recurring decimal, is a number
Case closed.
