What does eightvo mean?
'Eightvo' is not an established entry in standard English dictionaries, and no verified definition can be confidently given for it. Readers encountering the form are almost certainly looking for 'octavo', the well-attested bibliographical term for a book whose pages are printed on sheets folded three times to produce eight leaves or sixteen pages. Octavo sizes were especially common from the sixteenth century onward and remain standard vocabulary in book collecting and descriptive bibliography. Because no authoritative sense of 'eightvo' exists in reputable reference works, any specific meaning assigned to it here would be speculation rather than documented fact; verification against primary sources is recommended before treating it as valid vocabulary.
