Volume and chapter lists from Wikipedia (CC BY-SA 4.0). Chapters carry the volume they were collected in, not a date; only the first 13 kanzenban volumes have details listed. VIZ’s own pages do not allow automated reading, so only its original Dragon Ball and Dragon Ball Z split and Super are listed.
