# Hierarchical relationships between publications

You can now link publications hierarchically with the **Parent publication** field.

This groups the volumes of a multi-volume publication, and users can find all parts of a book more easily.

**Example:**

Take the multi-volume book “Beton-Kalender 2024” with parts 1 and 2.
You would create three publications in Librario:

- “Beton-Kalender 2024”
- “Beton-Kalender 2024, Teil 1”, which has “Beton-Kalender 2024” as its parent publication
- “Beton-Kalender 2024, Teil 2”, which also has “Beton-Kalender 2024” as its parent publication
