In addition to the international identifiers, all works created by the Publications Office are assigned an internal identifier, i.e. a catalogue number.

This is an internal Publications Office management tool, used for distribution purposes. It is used to categorise publications in catalogues, among other things. It is also used as an identification key in various IT applications.

The catalogue number is printed on the back cover, in the upper right-hand corner; if that is not possible, it must be clearly visible elsewhere on the work.
