I will discuss how, by simply making better use of existing information, it is possible to extract nearly one million quasars from extant multi-band data sets. Upcoming large-scale, synoptic surveys such as LSST will allow for more than an order of magnitude in further gains. Such large samples, pushing to faint limits over wide areas and with accurate photometric redshifts allow for powerful statistical analyses. For example, constraining 1) galaxy formation/evolution models by determining the luminosity dependence of quasar clustering, 2) merger models from the distribution of binary quasars, 3) cosmological parameters through cosmic magnification, and 4) dark energy through the Integrated Sachs-Wolfe Effect.
