Abstract
A tag module is a generalization, in any abelian category, of a torsion abe lian group. The theory of such modules is developed, it is shown that count ably generated tag modules are simply presented, and that Ulm's theorem hol ds for simply presented tag modules. Zippin's theorem is stated and proved for countably generated tag modules.
