Heat capacity measurements have been extensively used in deriving fundamental parameters of many materials related to the occurrence of superconductivity at low temperatures. For samples with compositional and microstructural heterogeneity, heat capacity measurements are of particular importance in elucidating the abundance of superconducting components and the transition width and distribution. The same technique has also played an active role concerning the interrelation ship between superconductivity and magnetism as well as lattice instability. Since these concerns are now being carried over to the new class of high temperature superconductors, this paper makes brief remarks following several examples from earlier low temperature studies.
