Oxygen overabundances in metal-poor stars were first derived by Conti etal. (1967, ApJ, 148, 105) and Sneden etal. (1979, ApJ, 234, 964), who give a value [O/Fe]= +0.6 for the most metal-poor stars. Controversies on the absolute value of the oxygen overabundance were started with the works by Gratton & Ortolani (1986, A&A, 169, 201) and Barbuy (1988, A&A, 191, 121), who claimed that the overabundance should be [O/Fe] s 0.4, and constant in the halo.
