No, I’m talking mostly about British copyright law prior to the nominal prioritization of creators in the Statute of Anne (1710).
(Techhically, it was focussed on printers rather than publishers, but the separation of function of those is a more modern arrangement.)
You can tell the part you target isn't about modern US copyright law because I later in the same post distinguish all US copyright law under the Constitution (which includes modern US copyright law) from it.
