Abstract:	On the basis of photoemission results on La_2-xSr_xCuO_4-y and YBa₂Cu₃O_y it is suggested that carriers doped in the otherwise insulating samples are oxygen p holes rather than Cu d holes. The p holes interact with the localized Cu d states through hybridization and may give rise to an anomaly near the Fermi surface as described by a periodic Anderson model with low carrier density.
