Main aim of the present paper is to discuss possible refinements of the strong law of large numbers for means of i.i.d. random variables \(X;X_ 1,X_ 2,...\). Several characterizations are obtained in terms of Césaro-, Riesz-, and “moving average”-summability. More general moment conditions than E \(| X|^ p<\infty\) can be handled by using general self-neglecting functions \(\phi\) instead of \(\phi (x)=x^{1/p}\). Finally, it is briefly outlined how the results relate to certain almost sure invariance or non-invariance principles for partial sums. For sake of comparison several references are provided concerning the ergodic, dependent or Banach-valued cases.
