In recent times much effort has been devoted to the improvement of mathematics teaching on alllevels. Thus it is only natural that we search for further stimulants and improvements in this direction, as well as for new means of discovering and developing the dormant abilities which may exist in our society. The Monograph Project of the School Mathematics Study Group has such a purpose. The present translation of the Hungarianproblem collection of the Eotvos Competition serves this goal.
Since I aro one of the few still existing links between the present mathematical generation and an older one that witnessed the first phase of the interesting development of this competition, I was asked to write a few introductory words to the English version of this collection.
