Documented in this Astronomical Journal paper

USNO-B is an all-sky catalog that presents positions, proper motions, magnitudes in various optical passbands, and star/galaxy estimators for 1,,, objects derived from 3,,, separate observations. The data were obtained from scans of 7, Schmidt plates taken for the various sky surveys during the last 50 years. USNO-B is believed to provide all-sky coverage, completeness down to V = 21, arcsecond astrometric accuracy at J, magnitude photometric accuracy in up to five colors, and 85% accuracy for distinguishing stars from non-stellar objects.

The catalog's size is about 80 GBytes and the only way to get it is to make a copy from someone who already has it.

It can be searched at Flagstaff at manicapital.com

Software for searching the USNO-B is in WCSTools from release onward.
