In this paper, we present a new method for finding identities for hypergeoemtric series, such as the (Gauss) hypergeometric series, the generalized hypergeometric series and the Appell-Lauricella hypergeometric series. Furthermore, using this method, we get identities for the hypergeometric series F (a, b; c; x); we show that values of F (a, b; c; x) at some points x can be expressed in terms of gamma functions, together with certain elementary functions. We tabulate the values of F (a, b; c; x) that can be obtained with this method. We find that this set includes almost all previously known values and many previously unknown values.
