How can I tell whether a DDC number was assigned intellectually or by machine?

In the German National Library’s catalogue, DDC numbers are identified in the title data with the note “maschinell ermittelte DDC-Kurznotation” (“machine-generated DDC Short Number”).

Full DDC numbers that have been assigned intellectually do not have this note; instead the DDC edition is cited in square brackets after the number: [DDC22ger] or [DDC23ger].
