Daniel McInerney,Pieter Kempeneersre exactly those isomorphic to categories of modules that are fully embedded into Ab. Rings giving rise to such modules are completely described. One of the curious special cases is provided by the full subcategory of Ab consisting of all torsion-free, divisible Abelian groups, which can be characte
