We present a summary of data obtained with the 350um polarimeter, Hertz, at the Caltech Submillimeter Observatory. We give tabulated results and maps showing polarization vectors and intensity contours. The summary includes over 4300 individual measurements in 56 Galactic sources and two galaxies. Of these measurements, 2153 have P>=3{sigma}_p_ statistical significance. The median polarization of the entire data set is 1.46%.
