  Using a simple classical method we derive bilateral series identities from
terminating ones. In particular, we show how to deduce Ramanujan's 1-psi-1
summation from the q-Pfaff-Saalschuetz summation. Further, we apply the same
method to our previous q-Abel-Rothe summation to obtain, for the first time,
Abel-Rothe type generalizations of Jacobi's triple product identity. We also
give some results for multiple series.
