NOW...
Is ANYONE going to answer my question?
There's no need to shout.
It's rude, and before you resorted to such rudeness you should have considered why you didn't get the responses you'd hoped for.
I'll tell you what. I'll give you a few clues.
Your questions are vague and confusing.
You titled this thread,
What's your editing style?
Then you asked this question:
I'm interested in hearing from various editors here what their process looks like.
My editing style depends who I'm working for, what their house-style requires, and most importantly, what's best for the book I'm working on.
My editing process looks dull: just me, sitting at a desk with a heap of papers and a few sharp pencils, or a Word document open on my laptop with Track Changes running.
There. I've answered the questions you asked, but I suspect that's not really what you're after.
I think what you really want me to do is to describe how I edit books. If that's the case, you're out of luck. I don't have the time to write the long essay that would require; nor am I inclined to do so for someone who is happy to post seriously-flawed work on his blog, and who therefore doesn't seem to value the editing process at all.
I feel particularly disinclined to do so when the person requesting such information writes blog posts about the editing process for his publisher: I'm not in the business of providing anyone with free blog-fodder. If you, or they, would like me to write such an essay I would be happy to oblige, so long as I'm paid in accordance with SoA guidelines.
I've already recommended to you by PM a couple of books you might find useful: Carole Blake's From Pitch to Publication, and Teresa Nielsen Hayden's Making Book (I hope I've spelled her name correctly). Have you read them yet?
If you do the smallest bit of searching at AW you'll find plenty of other book recommendations which should help you.
If you need guidance with your own editing work then I suggest you ask your employer (Champagne Books?). You could share with us their preferred methods and systems, which others might find useful. The best place for that would be in the appropriate thread in our BR&BC room.
