Dear Colleague

On behalf of the editors of IUCr Journals and the staff at the IUCr in Chester, we would like to recognise and thank you for your invaluable contribution to the journals in your role as reviewer.

The peer-review process is crucial in upholding not only the quality and validity of individual articles, but also the overall integrity of the science being disseminated. We greatly appreciate the important role you play in the advancement of science and the delivery of accurate peer-reviewed material to the community.

To express our gratitude, we should like to offer you a voucher for a free article in IUCrJ, the IUCr's new open-access high-influence journal, which is being launched to celebrate the International Year of Crystallography 2014.

Your discount voucher code is dis-OdNxEit1UH0oowsOum5, which is valid until 30 September 2014. Please follow the links at www.iucrj.org to submit your paper to IUCrJ for consideration. We look forward to receiving an article from you.

In the meantime, seasons greetings and best wishes for a happy IYCr2014!

Best wishes
