The Hamburg Quasar Survey (Hagen et al. 1995) is a wide-angle objective-prism survey to search for bright (B<17.5) quasars in the northern sky. The survey was carried out from 1980 to 1997 with the 80cm Schmidt telescope on Calar Alto, covering 13600 square degrees of the northern sky (delta>0) at high galactic latitudes (|b|>20). The dynamic range of the survey is 13<B<18.5 and the spectral coverage is 3400-5400A with a resolution of 45A at Hgamma.
