The data for the brighter half are included in ApJ Supp 1992, 83, 29; the data for the fainter half are included in ApJ Supp 1995, 100, 69. The survey contains 9897 objects selected from the IRAS database according to the following criteria: <pre> F60 > 1.2 Jy; F60<sup>2</sup> > F12 f25; |b| < 5; high source density flag at 60 microns not raised. </pre> Thus, this database consists of both galaxies and Galaxian contaminants. The sample contains ~5320 galaxies, and 14 objects without identifications at the present time.
