Query: Double integral of logarithm and exponential function expressed in terms
  of the Lerch function   In this work the authors use their contour integral method to derive a double
integral connected to the modified Bessel function of the second kind and
express it in terms of the Lerch function. There are some useful results
relating double integrals of certain kinds of functions to ordinary integrals
for which we know no general reference. Thus a table of integral pairs is given
for interested readers. The majority of the results in this work are new.
