| Summary:
We present a catalog of 97 uniformly-vetted candidates for quadruple star
systems. The candidates were identified in TESS Full Frame Image data from
Sectors 1 through 42 through a combination of machine learning techniques and
visual examination, with major contributions from a dedicated group of citizen
scientists. All targets exhibit two sets of eclipses with two different
periods, both of which pass photocenter tests confirming that the eclipses are
on-target. This catalog outlines the statistical properties of the sample,
nearly doubles the number of known multiply-eclipsing quadruple systems, and
provides the basis for detailed future studies of individual systems. Several
important discoveries have already resulted from this effort, including the
first sextuply-eclipsing sextuple stellar system and the first transiting
circumbinary planet detected from one sector of TESS data.
