A new sample of faint Gigahertz Peaked Spectrum (GPS) sources is presented here as an addition to our previous one (Ohanian, 1995). Comparison of the results of investigation of these samples with those of previously studied brighter samples (e.g. O'Dea et al. 1991) will delineate the properties of GPS sources over a wide range of luminosity, redshift and rest frame peak frequency. This will give noticeable information relevant to their cosmological evolution and relationship with other classes of extragalactic radio sources.
