We have initiated a dedicated search for new CVs, selecting candidates on the base of their spectroscopic properties in the Hamburg Quasar Survey (HQS), which lead up to now to the identification of 50 new CVs and a dozen good candidates. Using the HQS data of the previously known CVs for extensive tests of our selection scheme, we demonstrate that our survey should be very efficient in finding short period systems as long as they have emission lines with equivalent widths >=10 A. So far, orbital periods have been measured for 15 of the new CVs, with the surprising result that only two systems lie at or below the lower boundary of the period gap. This - somewhat preliminary - result is in uncomfortable disagreement with the predictions of the standard scenario of CV evolution.
