Abstract : Many materials were prepared which we believe are close to a metal-insulator boundary. Some of these materials were new compounds. Others were based on known compounds, but the composition was systematically varied to move close to the metal-insulator boundary. Superconductivity frequently occurs near such boundaries. Most of the materials prepared were oxides. However, some new oxysulfides and oxyselenides were also prepared. None of the samples produced showed evidence of superconductivity down to 5K.
