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.
In all cases the author of the new work must include an acknowledgement of the source of the material in the form: "From [Author (Year, Figure No.)]. Reproduced with kind permission of The Clay Minerals Society, publisher of Clays and Clay Minerals." Then please include the complete citation of the specific work in the list of references.
Individual readers of CMS Publications, and nonprofit libraries acting in their behalf, are freely permitted to make fair use of the material in it, such as to copy an article for use in teaching or research. Authorization to photocopy items for internal or personal use, or the internal and personal use of specific clients, or for educational classroom use, is granted by THE CLAY MINERALS SOCIETY provided that the appropriate fee is paid directly to the Copyright Clearance Center, 222 Rosewood Drive, Danvers, MA 01923, USA, (978) 750-8400, FAX: (978) 750-4470, web site: www.copyright.com. Permission is hereby granted to quote from Clays and Clay Minerals and in the Workshop volumes in scientific works when an acknowledgment of the source accompanies the work. Reprint of a figure, table, photograph, or other excerpt requires written consent of THE CLAY MINERALS SOCIETY. Republication or systematic or multiple reproduction of any material in Clays and Clay Minerals or the Workshop volumes ( including abstracts) is permitted only under license from THE CLAY MINERALS SOCIETY.
Permission to reproduce material from CMS publications is not given by default. That is, requests including phrases such as "if I do not hear from you by (some date), I will assume that consent is given" is not a substitute for explicit permission from CMS.

Please allow one to two weeks for processing and mailing of simple permission requests. It may take longer for complicated requests covering a great deal of material or complicated usages. Urgent requests usually cannot be accommodated. E-mail permissions are presently not given because they are not legal documents.
There are no processing fees.
License fees for actual usage may be assessed, depending on the proposed usage. License fees are assessed when the proposed usage is large, commercial in nature, or when it may result in a distribution that would compete with the CMS publication.
Approval for electronic capture of complete CMS journal and book articles is usually not given because it competes directly with CMS's own distribution of print and electronic matter. When it is permitted, appropriate license fees may be assessed, and a contract stating the limits of such capture and distribution is required.
