I see used booksellers often use the terms 8 VO or 8 VO possibly 9, The numbers usually ranging from 7 to 9

I havent been able to find a definition

VO very old ?

It is an abbreviation for the paper size. 8vo is octavo. 4to is quarto. “fo” is folio. 12mo is duodecimo.Steepleman (t) 08:33, 29 May 2021 (UTC)Reply
