Nearly 1500 sq deg of the northern Galactic plane were surveyed for rapidly rotating pulsars using the 76-m Lovell telescope. The sampling rate was such that there was sufficient nominal sensitivity to detect pulsars with periods as short as 0.6 ms. To overcome the effects of dispersion, scattering, and galactic background radiation, the high frequency of 1420 MHz was used to survey the inner Galaxy, while lower frequencies of 928 and 610 MHz were used for regions further from the Galactic center. PSR 1937 + 21 was detected in the survey, but no new pulsars were discovered. This is consistent with the results of other recent surveys and suggests that rapidly rotating, high-luminosity pulsars are not very common in the Galactic disk.
