copyright 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. Often that copyright is formally transferred to the publisher in the case of a scientific article accepted for publication. This allows the publisher to manage permissions and other functions on behalf of the author; the author, however, retains extensive rights of fair use to the original material. Sometimes, however, the author (or the author's employer or funding body) retains copyright, and licenses the publisher to discharge certain specific rights of dissemination and redistribution. Also, especially for the results of government-funded research, copyright is sometimes waived.

Author rights after acceptance

IUCr copyright

Articles for which the authors have transferred copyright to the IUCr carry a statement

on their initial page.

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:

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

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. Copyright in supplementary materials that represent an author's creative work (e.g. mathematical appendices, extended discussion, additional figures) will follow that of the primary article, i.e. transferred to the IUCr or reserved by the author. 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 for bona fide research purposes within the scientific community so long as proper attribution is given to the source from which they were obtained.
