corrector

One who corrects.

Wisdom is not the most severe corrector of folly.

Time! the corrector where our judgments err, The test of truth, love,—sole philosopher, For all beside are sophists, […]

A proofreader.

Seeing therefore those who now possess the employment by all evident signs wish themselves well rid of it; and that no man of worth, none that is not a plain unthrift of his own hours, is ever likely to succeed them, except he mean to put himself to the salary of a press corrector; we may easily foresee what kind of licensers we are to expect hereafter, either ignorant, imperious, and remiss, or basely pecuniary.

To have a competent knowledge of what has been recited, besides a quick and discerning eye, are the proper accomplishments by which a Corrector may raise his own and his Master's credit: for it is a maxim with Booksellers, to give the first edition of a work to be done by such Printers whom they know to be either able Correctors themselves, or that employ fit persons, though not of Universal learning, and who know the fundamentals of every Art and Science that may fall under their examination.

A director or governor.
