We are writing to you about IUCrData, the new open-access data publication from the International Union of Crystallography. This innovative publication aims to provide short descriptions of crystallographic datasets and datasets from related scientific disciplines, as well as facilitating access to the data.

The first phase of this venture provides a new home for the short structural reports previously published in Acta Crystallographica Section E. As well as giving a description of the structure and details of the synthesis and crystallization, Data Reports in IUCrData also include an interactive 3D structure representation. Readers are able to access the complete diffraction data, the submitted crystallographic information file (CIF) and the full checking output.

Use of the IUCr's publCIF software makes submission of a Data Report to IUCrData easy. publCIF can be downloaded free of charge from http://iucrdata.iucr.org/services/cif/publcif.
