A folio broadside dated 1619, of which a unique copy is preserved in the Society of Antiquaries of London, may be the earliest record of the prices of bookbinding agreed by the binders of London and Westminster. It is entitled A generall note of the prises for binding of all sorts of bookes.
Another edition of this pamphlet appeared in London in 1646. The text of that is available from Early English Books Online at this link.
