The SDSS-II project Galaxy Zoo was initiated in July 2007. Its goal is to have the general public classify galaxies automatically detected in the SDSS-II data. Using the Galaxy Zoo web interface and the corresponding SDSS-II data, we have classified the galaxy type of over 400 galaxies. We have correlated the galaxy type with position on the sky, color, and redshift. Due to the isotropic nature of the universe, we do not expect any significant patterns to appear. We have also identified several groupings of galaxies with similar sky positions and distance and determined the fraction of spiral and elliptical galaxies in each; because of galaxy mergers, the proportion of elliptical galaxies should be higher in denser groupings. We will report on the results of these investigations at the meeting.
