Novum Organum

The 1620 London folio is the true first of Novum Organum and there is no earlier or competing edition; Bacon wrote in Latin and published in London, so no original-language-versus-translation question arises. The census claim naming "Bonham Norton and John Bill" is the standard ESTC and Gibson attribution and correctly describes the first issue's colophon, but it should not be read as a title-page imprint. The important correction is to issue precedence, which is easy to get backwards and is frequently reversed in dealer copy: the presence of Norton in the colophon marks the FIRST issue, and his removal — together with the cancellation of e3 and the printing of errata on e4 — marks the SECOND. Bacon's Essayes are a separate high spot on their own footing, not part of this book, and both are collected.
