Results are reported from a search for QSO candidates (to limiting magnitude 20.5 mag at 300-510 nm) in the NE quarter of sky region 823 on low-dispersion UK Schmidt telescope objective-prism plates. The survey method and criteria, magnitude and wavelength calibrations, and spectral-line identifications are explained; and data on 122 objects of quality class 4 or better are presented in a table. Finding charts are also provided.
