North America has the largest archaeomagnetic directional data set in the world, about 5,000 results, but the exact number is difficult to estimate because the data have been published in a wide variety of (sometimes obscure) publications. In this project, the North American archaeomagnetic directional and paleointensity data will be collated, and incorporated into a modern, microcomputer-based, relational data base management system. This database will be made available to investigators in paleomagnetism, archaeomagnetism, geomagnetism, and archaeology.
