The procedure for new authors is very straightforward. You simply create a personal account by filling in the above fields in order to create new definitions. You have to identify yourself by a recognizable name, in the form FirstnameName. The second step is to send an email to the Editor-in-Chief, dicteditor@iucr.org in order to be given ‘author’ permissions within the ODC system. It is of course highly recommended that authors are also registered in the World Directory of Crystallographers.
