  Using a filter in the GROWTH Marshal based on color and the amplitude and the
timescale of variability, we have identified 372 objects as known or candidate
cataclysmic variables (CVs) during the second year of operation of the Zwicky
Transient Facility (ZTF). From the available difference imaging data, we found
that 93 are previously confirmed CVs, and 279 are strong candidates. Spectra of
four of the candidates confirm them as CVs by the presence of Balmer emission
lines, while one of the four has prominent HeII lines indicative of containing
a magnetic white dwarf. Gaia EDR3 parallaxes are available for 154 of these
systems, resulting in distances from 108-2096 pc and absolute magnitudes in the
range of 7.5-15.0, with the largest number of candidates between 10.5-12.5. The
total numbers are 21% higher than from the previous year of the survey with a
greater number of distances available but a smaller percentage of systems close
to the Galactic plane. Comparison of these findings with a machine learning
method of searching all the light curves reveals large differences in each
dataset related to the parameters involved in the search process.
