We are writing to let you know that the impact factor of IUCrJ has been revised up to 5.3.

This news follows on from the successful launch of the journal in 2014, which saw many outstanding papers published. IUCrJ is a fully open-access peer-reviewed journal that has already attracted publications from many of the leading names in the field of crystallography and beyond.

The journal publishes high-profile articles on all aspects of the sciences and technologies supported by the IUCr, including emerging fields where structural results underpin the science reported in the article. IUCrJ is thus the natural home for high-quality structural science results. Chemists, biologists, physicists and material scientists are actively encouraged to report their structural studies in IUCrJ.

We would like to thank all the authors, reviewers and editors who have contributed to the success of the journal. Below we list the top ten most highly cited papers published in the journal so far

We would ask you to consider IUCrJ – the leading journal in the crystallography category of the Science Citation Index – when you are planning your next paper. We look forward to receiving your submissions.

Best wishes
