The ISOPHOT Serendipity Survey utilized the unused slew time between pointed observations of the Infrared Space Observatory for strip scanning measurements of the sky in the far-infrared at 170 micron. During ISO's lifetime, more than 12000 slew measurements totaling nearly 500 hours were collected. The total slew length exceeds 150000 degrees, corresponding to an sky coverage of about 15%. The ISOPHOT Serendipity Survey is the only large scale sky survey in the unexplored wavelength region beyond the IRAS 100 micron limit to date. From the Serendipity database, a catalogue of 170 micron fluxes for more than 2000 galaxies has been established, most of which have not been observed before at this wavelength. It represents the largest galaxy sample homogeneously observed at 170 micron to date, providing for the first time temperatures and masses of the cold dust component in a large number of galaxies. It allows the selection of well-defined sub-samples of different galaxy types for the study of the integrated FIR properties and the search for rare types of galaxies. Initial statistical results of the whole catalogue and sub-samples of various galaxy types as well as first results of follow-up observations of interesting objects will be presented.
