In each issue there are also the headings: "Editorial"; "Cover", an important contribution or an interview; "Image", that is a drawing or a graph, commented by a scholar; "Readings/Re-readings", parts of books that have been or are particularly relevant for the cultural area; "The UID library", that is a showcase of editorial reports; "Events", critical readings of conferences / seminars / workshops carried out for local initiatives.

One of the two annual issues, largely on a specific but fairly broad theme, is written after an explicit call open to all.

 The other issue, instead, is mainly dedicated to a reflection on the themes of the last annual UID Conference.
