We present results from a study of HI selected galaxies that fall within both the HI Parkes All Sky Survey (HIPASS) and the Sloan Digital Sky Survey (SDSS). By comparing the optical properties derived from the SDSS 5-band photometry with the HI properties from HIPASS, we are able to probe the relationship between the stellar populations and the neutral gas over a range of Hubble types. Our HIPASS/SDSS catalog provides a uniform, homogeneous data set that can be used to investigate the factors that contribute to star formation on global scales. The HI selection has allowed us to identify a significant group of low surface brightness galaxies, not included in most SDSS studies. In addition, the construction of this catalog has led to a set of tools to aid in the analysis of large nearby galaxies in the SDSS.
