abstract = "Using selection criteria based on amplitude, time, and color, we
have identified 329 objects as known or candidate cataclysmic
variables (CVs) during the first year of testing and operation of
the Zwicky Transient Facility. Of these, 90 are previously
confirmed CVs, 218 are strong candidates based on the shape and
color of their light curves obtained during 3-562 days of
observation, and the remaining 21 are possible CVs but with too
few data points to be listed as good candidates. Almost half of
the strong candidates are within 10 deg of the galactic plane, in
contrast to most other large surveys that have avoided crowded
fields. The available Gaia parallaxes are consistent with sampling
the low mass transfer CVs, as predicted by population models. Our
follow-up spectra have confirmed Balmer/helium emission lines in
27 objects, with four showing high-excitation He ii emission,
including candidates for an AM CVn, a polar, and an intermediate
polar. Our results demonstrate that a complete survey of the
Galactic plane is needed to accomplish an accurate determination
of the number of CVs existing in the Milky Way.",
