A repository of archaeometric research collections and records has been established at the Conservation Analytical Laboratory of the Smithsonian Institution. It will not only preserve analyzed artifactual and raw material that has been bequeathed to the Smithsonian Institution, but also maintain computer files of current and past analytical work in a form accessible to archaeologists and archaeometrists. This is a report on the origin and scope of this new enterprise, and a call to the archaeometric community to contribute information and materials to SARCAR.
