As the area of sky covered by the SDSS approaches 3000 square degrees and the number of redshift exceeds 200,000 we can start addressing detailed studies of large scale structure.

The papers in this session will use more data than ever before in measuring the large scale clustering of galaxies, both in angular and redshift space. The analyses presented in this session probe clustering on both small, nonlinear and the large scales, well in excess of 100 Mpc, where the cosmic fluctuations are still linear. These scales overlap with the ones probed by the current CMB experiments.

We have over 25 million galaxies with photometric redshifts in the SDSS today, providing a unique sky coverage of over 2000 square degrees. We present the first results of angular clustering using photometric redshifts for the brightest 10 million galaxies. We apply various selections based on both SED type and redshift, and also create volume limited samples via cuts on absolute magnitude. The size of the sample enables us to make rather fine cuts in galaxy type. These first results give the most detailed view of the type dependence of galaxy clustering to date.
