This is the paper that introduced the "no-cloning" principle to quantum mechanics.
Of course, no-cloning is an immediate corollary of the linearity of quantum mechanics. The real contribution of this paper was to take this simple observation and to publicize it to physicists, making clear the philosophical implications.
