The authorizing citations have moved from being printed in the outer margins on the side of the page to the bottom of the page, a practice we would describe as footnotes.

Tryal of Richard Francklin, 1731 (A1r)

The 1731 imprint date suggests that the publication of this chapbook followed almost immediately after the conclusion of the December 3, 1731 trial. Chapbooks like these---small unbound pamphlets---were a prime source of news as well as entertainment.

Verkündigung der Bulle Pastoris, 1479

This 1479 papal bull from Pope Sixtus IV features two nearly-identical collation notes by papal notaries, identified by their initials in the seals to the left of their notes as Gregorius May and Mathias Horn.

At first glance, this page looks free from error and correction. But on a closer look, you can see that the last line of text has been added after the main text was printed---the last word of the line is printed over the original catchword and the ink is a slightly different color.

Vincent, Discouerie, 1622 (π1r)

The title page of this work is a bit confusing, and lengthy, because it first names the author of the work in which mistakes have been discovered, before naming the author of this work.
