We have undertaken a campaign to expand the census of WRs throughout the Galaxy using the 2MASS and Spitzer/GLIMPSE surveys. Free-free emission generated within the ion-dense winds of WRs generates a significant infrared excess which forms the basis of an excellent criterion for photometrically selecting WRs from the stellar field.
