The NRAO seven-beam receiver was used on the former Green Bank 91 m telescope, during 1986 November and 1987 October, to repeatedly survey the declination band (0° < δ < +75°) at 4.85 GHz. This data base has been used to extract variability information for sources in the GB6 catalog, a large unbiased sample of sources derived from the combined survey images. Long term variability information (one year time base) is available for 97% of the 75,162 GB6 sources and short term variability (few day) is available for 20,963 sources. This large variability data base is available to the astronomical community through http://pulsar.physics.ubc.ca/gregory/index.html.
