  Motivated by recent pioneering measurements of galaxy kinematics at
intermediate redshifts, we have begun a pilot survey to measure rotation curves
for blue, star-forming galaxies between 0.05<z<0.35. The scientific impetus for
such measurements is to construct internal velocity - luminosity relations at
redshifts substantial enough to make cosmological and evolutionary tests.
Departures from a fiducial relation as a function of redshift are sensitive to
both space-time curvature and the evolution of the mass-to-light ratio in
galaxies. Because of this ambiguity -- curvature vs. evolution -- kinematics
should be viewed as a new cosmological tool at intermediate redshifts to be
combined with additional measurements. In particular, the apparent internal
velocities, colors, surface-brightness, and image shape are all unaffected by
curvature, so that this ensemble of observables can be used unambiguously to
explore galaxy evolution. Here we discuss a well-defined method of target
selection which assures efficient measurement of spatially and spectrally
resolved kinematics, namely rotation curves. Spatial resolution is critical
since it is difficult to use integrated line-widths to distinguish between, for
example, a low-mass star-forming galaxy and a high-mass galaxy with a central
star-burst. For 18 of 19 appropriately selected galaxies to B<20.5 from
Bershady et al (1994), we have successfully measured rotation curves using the
KAST spectrograph on the Lick 3m telescope with 1-2 hour integrations for each
target. As a sanity check, we present preliminary results for half of our
sample: We measure H0 to be ~75 km/s/Mpc at a median redshift of 0.15.
