For more on Mentelin's "very peculiar" transitional method of marking signatures see, William Blades, "The Use & Development of Signatures in Books," from Books in Chains and other Bibliographical Papers, 1892, pages 110-112. The signatures are mostly preserved in this copy, as it has never been trimmed down.
