Improve visibility of volume number and title for multipart monograph

[salomerohr]

For multipart monograph, the volume number and multipart title are important and should be, if possible, more visible on the detailed display to easily distinguish the volumes and the multipart they are attached to:
https://catalogue.library.cern/literature/pcdbe-ncd44 -> Handbook of particle detection and imaging (vol: 2)
https://catalogue.library.cern/literature/a3eza-72r60 -> Handbook of particle detection and imaging (vol: 1)

proposal, placing "vol: 1" in the corner indicated by red rectangle, could be a <Label> to make it more visible

[salomerohr]

Yes, looks good!

Perfect for the volume number!
For the multipart title, I don't see any difference? would it be possible to make it more visible?
