We review the surveys for quasars that are being conducted with the Sloan Digital Sky Survey (SDSS) imaging data and highlight the need for supplementary multiwavelength observations. We stress that the SDSS is more than a redshift survey and discuss how the SDSS data can contribute to our understanding of the detailed physics of quasars. In particular, optical properties of SDSS quasars can be used to broaden our understanding of the UV/optical continuum, the broad emission line region, and the broad absorption line region. The ensemble average colors of large numbers of quasars promise to provide constraints on the optical/UV continuum emission mechanism. Investigation of emission line properties through analysis of continuum colors, line profiles, and microlensing can be used to trace the structure of the broad emission line region. The scope of the SDSS also means that large numbers of new broad absorption line quasars are being discovered; they can be used to determine whether all quasars have outflows.
