Line editing
'Very often I'm brought to a halt by some ridiculous mistake that hasn't been picked up by an editor, which makes me think there can't be much line-by-line editing going on in publishing houses these days. I don't know that it matters all that much. It makes a lot of people absolutely furious so they can hardly enjoy reading. But for me if what is being said comes clearly across that's what matters. It is a bit pedantic to fuss too much about the editing of detail. On the other hand, it does offend my personal instincts, having been trained in the old-fashioned ways, which meant our texts should be perfect.
The answer I found for myself is that I take much more trouble than I used to in the line-by-line editing of my own manuscript, and I think authors should now take that responsibility on themselves if they don't want to be annoyed by minor details. In nearly 50 years as an editor for André Deutsch, I never came across a writer who objected to editing if it made sense, not just in terms of mistakes, which all writers want to be corrected, but the actual way something was written. A lot of writers, for instance Jean Rhys, are perfectionists, so all the editor has to do is spot typing mistakes. I would never have dreamed of suggesting alterations. If we took a book on it meant we liked it; it might in certain respects or details be improved, but if the author didn't want to change it we didn't mess around with their texts.
