Abstract
I review the observations of gravitationally lensed quasars. These systems are important because they allow us to probe the properties of the lensing galaxies at various scales, and they also allow insights into the structures of the quasars themselves. Samples of quasar lenses also have the potential to act as cosmographic probes. These areas are described, together with observational and scientific prospects for the future.
