As part of a survey of quasar continuum spectra, a class of quasars is identified in which the optical-UV continuum big bump feature appears to be weak or absent, relative to both IR and X-ray. These weak bump quasars are otherwise normal objects and constitute a few percent of the quasar population.en-USQuasarsSpectrophotometryUltraviolet RadiationColor-Color DiagramSpectral Energy DistributionX Ray SpectraJournal Article2017-02-1310.1086/185540
