My philosophy as an Editor
Excellent editors make themselves aware of the writer’s audience, purpose, and context. No matter if the text is a technical report, an instruction, an essay, a memoir, a professional article, and many other document types, an editor must be aware of why the writer is writing, to whom the writer is writing, and in what circumstances (physical, psychological, environmental, etc.) the writer is writing.
For over 20 years of both academic and private consulting, I have successfully helped writers develop interesting, readable texts. This doesn’t mean merely “proofreading.” Correct punctuation, grammar, spelling and other mechanics are second nature to any good editor. That is a given. Excellent editing is helping writers make their meaning clear to readers. Take technical or scientific research papers:
“It does not matter how pleased an author might be to have converted all the right data into sentences and paragraphs; it matters only whether a large majority of the reading audience accurately perceives what the author had in mind.” (From: “7 Keys to Clear Scientific Writing“)
