We present the summary results from the now completed Nearby Galaxies Supernova Search (NGSS) campaigns. These campaigns were conducted at KPNO 0.9-meter using the 8K x 8K MOSAIC camera. The wide-field provided by the camera (59\arcmin x 59\arcmin) allowed us to search nearly 750 square degrees of sky along the celestial equator for SNe, to a limiting magnitude of R~21. Using search algorithms similar to those used by the High-z Supernova Search Team and the Supernova Cosmology Project for their campaigns, we have processed over 1.25 TB (1250 GB) of Mosaic imager data in real time to discover a sample of 42 SNe of various types and ages. With facilities at CTIO and other target of opportunity observations, we have photometrically followed many of these SNe and obtained very well sampled light curves. We present a detailed description of our 3 year project, search techniques, light curves of several of our SNe, and preliminary rates.
