Author’s proof

The proof with the Author’s corrections marked in it. After the ordinary errors of composition—literals, turned letters, and the various defects arising from hasty workmanship are rectified, a clean proof is pulled to be sent to the Author, who returns it marked with such alterations or amendmends as hte may think proper. These alterations, when made by the Compositor, are charged for, whereas ordinary corrections are not. (See Proofs).
