  We report on the status and plans of experiments now running or proposed for
electron-positron colliders at energies between the $\phi$ and the Z. The
$e^{+}e^{-}$ B and charm factories we considered were PEP-II/BABAR, KEKB/Belle,
superKEK, SuperBABAR, and CESR-c/CLEO-c. We reviewed the programs at the $\phi$
factory at Frascati and the proposed PEP-N facility at Stanford Linear
Accelerator Center. We studied the prospects for B physics with a dedicated
linear collider Z factory, associated with the TESLA high energy linear
collider. In all cases, we compared the physics reach of these facilities with
that of alternative experiments at hadron colliders or fixed target facilities.
