The "Small Scale Structure Catalog (SSS)" is a companion to the "Point Source Catalog" for extended sources larger than pointlike but smaller than 8 arc-min, listing objects such as galaxies, planetary nebulae, or compact H II regions. The catalog contains 16,740 sources. In spite of every effort to select only resolved, well-defined, and isolated sources for inclusion in the catalog, a few problems remain. At low signal-to-noise ratios, the researcher is cautioned in deciding whether a source is resolved or not. This data set is on a tape containing a file ordered by right ascension. For more information on this data set, see "IRAS Small Scale Structure Catalog," by George Helou and D.W. Walker, IPAC, 100-22, Caltech, Pasadena, CA 91125.
