The SDSS and SDSS-II projects (York et al., 2000) have just published their final data archive, consisting of five-band images over 1/4 the sky, a catalog of over 350 million objects, and spectra for 1 million galaxies, 100,000 quasars, and 240,000 stars. The data volume consists of 73 terabytes in files and 18 terabytes in databases.
Of the over 800 papers published so far using SDSS data, over half are analyses by astronomers outside the SDSS collaboration using the public data releases. This talk examines the ways in which the SDSS data are used, including multi-wavelength analyses matching data from the xray to the radio. Several VO interfaces are now available that provide access to the data in parallel with the SDSS-only interfaces. Positive and negative aspects of these interfaces will be discussed. Future surveys that are designed to overlap with the SDSS footprint are also mentioned briefly.
