Abstract
When faced with mathematical material, editors with limited technical training often address only superficial concerns such as format and punctuation. A few simple guidelines are presented here which can help one do a more complete job. Superfluous symbols should be deleted; the remaining symbols should be defined properly, redefined where necessary, and used according to the rules of grammar.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
