  We produce the most comprehensive public void catalog to date using the Sloan
Digital Sky Survey Data Release 7 main sample out to redshift z=0.2 and the
luminous red galaxy sample out to z=0.44. Using a modified version of the
parameter-free void finder ZOBOV, we fully take into account the presence of
the survey boundary and masks. Our strategy for finding voids is thus
appropriate for any survey configuration. We produce two distinct catalogs: a
complete catalog including voids near any masks, which would be appropriate for
void galaxy surveys, and a bias-free catalog of voids away from any masks,
which is necessary for analyses that require a fair sampling of void shapes and
alignments. Our discovered voids have effective radii from 5 to 135 h^-1 Mpc.
We discuss basic catalog statistics such as number counts and redshift
distributions and describe some additional data products derived from our
catalog, such as radial density profiles and projected density maps. We find
that radial profiles of stacked voids show a qualitatively similar behavior
across nearly two decades of void radii and throughout the full redshift range.
