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’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 but note that for journal content, please request  permission via the Copyright Clearance Centre which can be accessed via the journal by clicking on the ‘Rights and Permissions’ link found on the right hand side of the page where the specific article of interest is displayed.

  • 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  • the right to include the article in full or in part in a thesis or dissertation (provided that this is not to be published commercially);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.)].

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.
