A surprisingly large number of research disciplines have contributed towards the development of knowledge on lazy problem solving, which i s c haracterized by its storage of ground cases and its demand driven response to queries. Case-based reasoning (CBR) is an alternative, increasingly popular approach for designing expert systems that implements this approach. This paper lists pointers to some contributions in some related disciplines that o er insights for CBR research. We then outline a
