I present results from the SDSS DR5 Spectroscopic Quasar survey,
examining the clustering properties of quasars via the 2-point correlation
function. The evolution of quasar host haloes is discussed and put in
context with other recent observational measurements (e.g. from the 2SLAQ
and AGES surveys) and comparisons to theoretical models are made,
including potential challenges to the "AGN Feedback" model.
We then look ahead to the high redshift part of the Baryon Oscillation Spectroscopic Survey (BOSS) which will use the existing SDSS telescope with upgraded spectrographs to obtain 160,000 and z=2.2-3.5 quasar spectra.
