The Clay Minerals Society (CMS) owns the copyright on all material published in Clays and Clay Minerals, and The Clay Minerals Society Workshop Volumes. Works prepared by U.S. government employees in the course of their work are in the public domain and are not copyrighted by CMS.
CMS obtains copyright ownership from authors as a professional service. CMS’s holding of the copyright centralizes the process and allows permission to be given even if the author(s) can no longer be located. This also prevents materials from becoming unusable by the community because of uncertainty about who holds the copyright. Anyone wanting to reproduce articles, figures, tables, etc. need only contact CMS for permission to do so. There is no charge for reproducing materials in most cases.
