Volume

The volume specification of a work on its title pages is reproduced in the detailed title data according to the original.

In the short title the abbreviated form "Bd. [number]" (Bd. = Vol.) is used. Basically, "Bd." is written regardless of the description of the volume (e. g. as "booklet" or "part") in the original.
