The total hadronic cross section for virtual photon-photon interactions is reported for center-of-mass energy, W, between 2 and 20 GeV. The data were obtained via the process e/sup +/e/sup -/..-->..e/sup +/e/sup -/..gamma..(..gamma..(..-->..e /sup +/e/sup -/+hadrons with both scattered e/sup +/ and e/sup -/ detected. Each photon's four-momentum squared, q/sup 2/, ranges from -0.1 to -1.6 GeV/sup 2/. Dependence upon q/sup 2/ agrees with a generalized vector-meson-dominance model. The total cross section shows little W dependence, averaging 125 nb at q/sub 1//sup 2/ = q/sub 2//sup 2/ = -0.3. Photon helicity interference terms are determined.
