Manuscript Preparation, Copyediting, and Proofreading

Q. For text following a long block quotation, is it a must to indent, even if adding a single line? It seems confusing (visually) to do so.

A. Indent only if you are starting a new paragraph. If the text continues the paragraph that precedes the block quotation, then it should begin with no indent. Please see CMOS 13.22 (“Text following a block quotation”).
