QUESTION: Should manuscripts be stapled or paper-clipped?
ANSWER: Both are acceptable, though stapling the entry pages together and affixing the entry form and check with a paperclip is preferred. Stapled entry pages reduce the risk of any pages getting lost in the shuffle. If we feel like a manuscript needs a staple, we'll add one at no charge. But we don't go so extreme as to discard entries that lack a staple or paperclip. We just add them where they're needed.
Of course, the best way to avoid any staple or paperclip issues is to submit your entries online.
