  We have performed a detailed study of dilepton production from pp collisions
including the subthreshold $\rho$ production via baryonic resonances (N(1520),
N(1700)) in addition to the conventional dilepton sources as $\pi^0, \eta,
\omega$ and $\Delta$ Dalitz decays and direct decays of vector mesons ($\rho,
\omega$). The role of baryonic resonances in $\rho$ production from
nucleon-nucleon collisions is studied in comparison to the DLS data which are
well described.
