Abstract: The purpose of this paper is to further the study of weakly injective and weakly tight modules a generalization of injective modules. For a Serre class K of modules, we study when direct sums of modules from K satisfies a property IP in K. In particular, we get characterization of locally q.f.d. modules in terms of weak tightness.
