Editorials
The journal publishes every three years an editorial describing the most salient facts about the last three years and some statistics about submissions, publications, country of origin, type of paper (invited survey, research paper, ...), duration of the reviewing process, rejection rate and so on. Here is the list of these triennial editorials.
In case of plagiarism, the journal has also published editorials describing the facts.
