A survey of the region 44-90 deg,/b/less than 1.5 deg has been nearly completed using the Westerbork Synthesis Radio Telescope at 327 MHz. The low frequency, high resolution, and high sensitivity of this survey make it ideal for detecting SNRs which previous, primarily single disk, surveys have missed. A total of 24 SNRs have been identified in the survey data, 11 of which are newly discovered. The survey thus nearly doubles the number of known SNRs in this region of the Galactic plane. Because of the characteristics of the survey, these new remnants have lower surface brightness and smaller angular size than previously detected SNRs. Some of the new remnants may be very distant, evolved SNRs. A possible excess of filled-center SNRs in the survey region (compared to the general population) is also noted.
