The publications of this series present the results of research and investigations conducted by the Bureau at its research centers or laboratories, or in mines, quarries, smelters, refineries, oilfields, plants and other non-Bureau properties. They differ from Bulletins in that they describe the principal features and results of individual experiments, minor research projects or a significant coordinated phase of a major project or program.
