copyright and licencing policy

Authorship of a scientific article is associated with certain intellectual property rights, protected within the framework of copyright laws. Under the most widespread international agreement, the Berne Convention, copyright in an article automatically belongs to the creator or creators of the article, except for works performed `for hire', in which case the employer or funding body may own the copyright in the work. Whether authors publish their article behind a paywall or as an open-access article, the IUCr does not require authors to transfer copyright. Instead, we offer authors the option to agree either a licence to publish or a CC-BY open-access licence.

Author rights prior to acceptance

Although authors retain full rights over their article prior to its acceptance for publication, there is a normal standard of good behaviour to safeguard the journal's investment of resources in peer review, and the confidentiality of the submitted article while it is in an unfinished form. Therefore, provided the authors acknowledge that the article has been submitted for publication in an IUCr journal, they may:

share print or electronic copies of the article with colleagues;
post an electronic version of the article on their personal website, their employer's website/repository and on free public servers (including preprint servers) in their subject area.

Author rights after acceptance

Licence to publish

Provided that a full bibliographic reference to the article as published in an IUCr journal is made, authors of such articles may, without needing to seek permission from the IUCr:

Share print or electronic copies of the article with colleagues.
Use all or part of the article and abstract, without revision or modification, in theses and/or dissertations, in personal compilations or other publications of their own work (and may receive a royalty or other payment for such work).
Use the article within their employer's institution or company for educational or research purposes, including use in course packs.
Post a copy of the author accepted manuscript on their own personal website, on their employer's website/repository and on not-for-profit repositories in their subject area. The site must give full attribution to the article and must provide a permanent link from the posting to the final published article on the IUCr website. A CC-BY licence may be applied to the author accepted manuscript, as required by some funders.
Post an authorised electronic reprint of the article on their own personal website, on their employer's website/repository and on not-for-profit repositories in their subject area. The site must give full attribution to the article and must provide a permanent link from the posting to the final published article on the IUCr website.

Readers of such articles may, without needing to seek permission from the IUCr:

Save to hard disk a local copy of the article for their personal use.
Print off one or more copies of individual articles for their personal use (they may not systematically download multiple articles or disseminate copies to third parties).
Include brief extracts from the article or abstract, or reprint figures and/or tables, without revision or modification, in their own publications so long as the original source is acknowledged and a full bibiographic reference given.

For all other uses, please see the pages "Permissions requests" and "Terms and conditions of use".

Open access

Authors of open-access articles will not be asked to transfer copyright to the IUCr, but will instead be asked to agree during article submission to an open-access licence. This licence is a Creative Commons Attribution (CC-BY) Licence, which provides for the re-use of the article in whole or part provided there is attribution for the article.

Supplementary materials and supporting data

It is the practice of IUCr journals to provide free access to all supplementary materials and supporting data files deposited with a published article. Licencing of supplementary materials that represent an author's creative work (e.g. mathematical appendices, extended discussion, additional figures) follows that of the primary article. Copyright protection is not extended to files of scientific data (e.g. structural data CIFs, structure factors, primary diffraction images), and such data sets may be used freely for bona fide research purposes within the scientific community so long as proper attribution is given to the source from which they were obtained.

Text and data mining

The IUCr encourages the use of text and data mining in research. Open-access content may be mined without restriction provided proper attribution is given; subscription content may be mined for non-commercial purposes.

Subscription and open-access content for text- and data-mining purposes may be downloaded directly from Crystallography Journals Online. We request that you limit your downloading speed to a reasonable rate. Researchers who do not have subscription access to IUCr Journals can send requests for text- and data-mining access to support@iucr.org.
