 Abstract: We present the second Open Gravitational-wave Catalog (2-OGC) of compact-binary coalescences, obtained from the complete set of public data from Advanced LIGO's first and second observing runs. For the first time we also search public data from the Virgo observatory. Our analysis is based upon updated methods to improve detection of compact binary mergers by incorporating corrections for short time variations in the detectors' noise power spectral density and instantaneous network sensitivity. We identify a population of 14 binary black hole mergers with $p_{\mathrm{astro}} > 0.5$ along with the GW170817 binary neutron star merger. We confirm the binary black hole merger observations of GW170121, GW170304, and GW170727. We also report GW151205, a new marginal binary black hole merger during the first observing run. No other individually significant binary neutron star candidates are found, nor did we observe any significant neutron star--black hole candidates. We make available our comprehensive catalog of events, including the sub-threshold population of candidates to enable deeper follow-up as our understanding of the underlying populations evolves.
