We are continuing a J, K and narrow-band imaging survey of 300 square degreesof the plane of the Galaxy, searching for new Wolf-Rayet stars. Our surveyspans 150 degrees in Galactic longitude and reaches 1 degree above and belowthe Galactic plane. The survey has a useful limiting magnitude of K = 15 overmost of the observed Galactic plane, and K = 14 (due to severe crowding) withina few degrees of the Galactic center. Thousands of emission line candidateshave been detected. In spectrographic follow-ups of 146 relatively bright WRstar candidates we have re-examined 11 previously known WC and WN stars anddiscovered 71 new WR stars, 17 of type WN and 54 of type WC. Our latest imageanalysis pipeline now picks out WR stars with a 57% success rate. Star subtypeassignments have been confirmed with K band spectra, and distances approximatedusing the method of spectroscopic parallax. Some of the new WR stars areamongst the most distant known in our Galaxy. The distribution of these new WRstars is beginning to trace the locations of massive stars along the distantspiral arms of the Milky Way.
