## Abstract

Some interesting aspects of the structure and stoichiometry of $YBa_2Cu_3O_7+\delta$ and other high-Tc oxide superconductors are discussed. The nature of $Cu$ and the importance of the $Cu^3^+/Cu^2^+$ ratio in these copper oxides are pointed out. Marginal metallicity of the non-superconducting phase in these oxides as an important factor in the mechanism is indicated. Effect of Y substitution in $YBa_2Cu_3O_7+\delta$ by other rare earths is commented upon
