I make sure I understand your message, and that your readers will understand it, too. I ensure that introductions, sections, summaries, and cross-references all harmonize. I break up long, rambling sentences into shorter, more readable ones. I bring important clauses from the tail end of the sentence to the beginning. I replace vague and inappropriate words.
Consistent style is the hallmark of polished, professional writing.
I ensure this by developing a style sheet for each manuscript as I edit, or adding to an existing style sheet. The style sheet establishes standards for consistent use of terms and elements. This is especially valuable when the manuscript has several authors. You can use my style sheet for future writing projects, too. I suggest possible answers and options, so you can simply indicate your choice.
