Old notices
These pages collect together notices posted on the IUCr web site in past years. They are retained for archival interest, but there is no guarantee (or likelihood) that many of the web links found in these notices will still be active.

For those who need more time, the abstract submission portal will remain open until 21 February 2023. In addition, the early bird registration deadline has been extended to 31 March 2023.
