If R is an associative ring, with unity, the R- module (the abelian group) M is said to have the direct summand sum property (in short D.S.S.P.) if the sum (that is the submodule (the subgroup) of M generated by the union) of any two direct summands ofM is again a direct summand in M. The present work gives descriptions of some classes of abelian groups with this property.
