Don't delay the return of proof for a few missing cross-references. Return to Top Page depth To avoid awkward breaks in page make-up, facing pages might be one line shorter or longer than the standard page length. The proofreader notes these variations, but you need not tend to them unless you are asked specifically to add or cut material. Return the marked page proof to your project editor. Keep the duplicate proof marked with your corrections for your files.
Symbols Use standard proofreading symbols.
Return to Top Marking Make corrections in a color that stands out from the black type. Then put the appropriate symbol in the nearer margin, beside the line in which the correction occurs. Do not write the actual correction within the type area. To indicate more than one correction in a line of type, place the marginal marks in order, left to right, and separate them by a diagonal slash. Return to Top Arrows Do not draw a guideline or an arrow from the point of correction to the marginal mark unless the relation between them would not otherwise be clear.
