In this paper, we study certain polylogarithmic double series ∞ m,n=1where p, q, r are nonnegative integers and x is any complex number with |x| ≤ 1. First we give certain polylogarithmic interpolation formulas of the results of Mordell, Subbarao-Sitaramachandrarao and Zagier. By specializing to x = 1, we can obtain their results. Secondly we calculate some special values of these polylogarithmic double series.
