Baryon acoustic oscillations (BAO) in large-scale structure provide an excellent standard ruler test to measure the cosmological distance scales (such as the angular diameter distance and the Hubble parameter), and therefore to probe dark energy properties. In this talk, I will discuss various aspects of BAO surveys, recent high-precision BOSS BAO measurements, and how reconstruction of BAO and other techiniques can be used to recapture cosmological information lost due to nonlinear evolution of structure.
