A run that starts (or jumps) at an old issue number, like Avengers #672 in 2017. Metron, ComicVine and the publishers' own sites (checked: Marvel.com, DC.com) keep each as its own volume; collector price guides file them under Vol 1. Longbox keeps both: its own volume number, and the old numbering on record. Case by case (D-017, D-021).
