Abstract : We study the normality of families of meromorphic functions sharing a set consisting of two or three distinct finite values to improve and extend Theorem 1 in Liu-Pang \cite{15} and Theorem 1.1 in Liu-Chang \cite{16}. Examples are provided to show that the results in this paper, in a sense, are the best possible.
Keywords : meromorphic functions, shared values, shared sets, normal families
