Copyright and The Clay Minerals Society

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.

If you are the author of the CMS-copyrighted material, you retain

  • the right to make copies of the article for your own personal use, including for your own classroom teaching use;
  • the right to make copies and distribute copies (including through e-mail) of the article to research colleagues, for the personal use by such colleagues (but not commercially or systematically, e.g. via an e-mail list or list serve);
  • the right to post a revised personal version of the text of the final article (to reflect changes made in the peer review process) on the author's personal or institutional web site or server, with a link to the journal home page (on;

  • for the author’s employer, if the article is a ‘work for hire’, made within the scope of the author’s employment, the right to use all or part of the information in (any version of) the article for other intra-company use (e.g. training);
  • patent and trademark rights and rights to any process or procedure described in the article;
  • the right to include the article in full or in part in a thesis or dissertation (provided that this is not to be published commercially);
  • the right to use the article or any part thereof in a printed compilation of works of the author, such as collected writings or lecture notes (subsequent to publication of the article in the journal); and
  • the right to prepare other derivative works, to extend the article into book-length form, or to otherwise re-use portions or excerpts in other works, with full acknowledgement of its original publication in the journal.

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.

Processing fees and license fees

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.

Electronic capture

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.

Posting on your Web Site

Posting on the World Wide Web of material covered by CMS's copyright is prohibited without specific permission from CMS. There is one exception. An author or group of authors may post without further permission, on their own personal or organizational website(s) the title, authors, and full abstract of their paper(s), providing

  • the posting cites the CMS publication in which the material appears,
  • the citation includes the address line: "The Clay Minerals Society, 3635 Concorde Pkwy Ste 500, Chantilly VA 20151-1125 USA (", and
  • the abstract as posted is identical to that which appears in the CMS publication.

After a period of two years since the time of publication has elapsed, authors may post a copy of their own paper on their personal or organizational website(s).
