Title: A conference on nonequilibrium thermodynamics

Abstract: In transformations involving stationary nonequilibria entropy might be a not well defined concept. It might be analogous to the heat content (once called ``caloric'') in transformations that are not isochoric (\ie which involve mechanical work): it could be just a quantity that can be transferred or created, like heat in equilibrium. The text summarizes the philosophy behind a recently proposed definition of entropy creation in nonequilibrium stationary systems.
