Full IUCr Journals open-access licence agreement
The full open-access agreement is identical to the Creative Commons Attribution Licence.
THE WORK (AS DEFINED BELOW) IS PROVIDED UNDER THE TERMS OF THIS IUCr JOURNALS LICENCE ("LICENCE"). THE WORK IS PROTECTED BY COPYRIGHT AND/OR OTHER APPLICABLE LAW. ANY USE OF THE WORK OTHER THAN AS AUTHORIZED UNDER THIS LICENCE OR COPYRIGHT LAW IS PROHIBITED. BY EXERCISING ANY RIGHTS TO THE WORK PROVIDED HERE, YOU ACCEPT AND AGREE TO BE BOUND BY THE TERMS OF THIS LICENCE. THE LICENSOR GRANTS YOU THE RIGHTS CONTAINED HERE IN CONSIDERATION OF YOUR ACCEPTANCE OF SUCH TERMS AND CONDITIONS.
This Creative Commons England and Wales Public Licence enables You (all capitalised terms defined below) to view, edit, modify, translate and distribute Works worldwide, provided that You credit the Original Author.
'The Licensor' [one or more legally recognised persons or entities offering the Work under the terms and conditions of this Licence]
agree as follows:
- "Attribution" means acknowledging all the parties who have contributed to and have rights in the Work, Derivative Work or Collective Work under this Licence.
- "Collective Work" means the Work in its entirety in unmodified form along with a number of other separate and independent works, assembled into a collective whole.
- "Derivative Work" means any work created by the editing, modification, adaptation or translation of the Work in any media (however a work that constitutes a Collective Work will not be considered a Derivative Work for the purpose of this Licence). For the avoidance of doubt, where the Work is a musical composition or sound recording, the synchronization of the Work in timed-relation with a moving image ("synching") will be considered a Derivative Work for the purpose of this Licence.
- "Licence" means this Creative Commons England and Wales Public Licence agreement.
- "Original Author" means the individual (or entity) who created the Work.
- "Work" means the work protected by copyright which is offered under the terms of this Licence.
- For the purpose of this Licence, when not inconsistent with the context, words in the singular number include the plural number.

4. Limit of Liability
Subject to any liability which may not be excluded or limited by law the Licensor shall not be liable and hereby expressly excludes all liability for loss or damage howsoever and whenever caused to You.
The rights granted to You under this Licence shall terminate automatically upon any breach by You of the terms of this Licence.
