Zero-growth theory (Zero-growth theory), also known as the steady state theory (Steady state theory), which was originally from the United States and British libraries put forward, after the world became a very effective control of the library collection increase in the number theory. So far, the world library community generally recognized and accepted this theory, the most authoritative explanation that came from in 1975 by the British University Grants Committee report published by Atkinson (The Atkinson report).
