Last week, the BBC Radio 4 program Open Book focused on the role of the editor in publishing a work. Host Mariella Frostrup interviewed five editors or author-editor combos about what value an editor–whose job didn’t really formally exist until after World War II–provides.

You can listen to the half-hour show here; the first 10 minutes alone are worth it just to hear Diana Athill talk about the unique editing requirements of Updike, Naipul, and Rhys. But here’s a summary of key points from the full episode:

• An editor can help shore up a writer’s weaknesses. Some writers may be masters of language, but need help shaping something into a finished work. Other writers may be great writers but lousy at taking care of other essential life tasks, so they would otherwise never write or publish without someone’s help.
• An editor is a guaranteed, and perhaps the only, extremely attentive reader a writer will have. Diana Athill says, “What one learns when you’re working with an eidtor, is that actually very few peole get their books read extremely attentively by anybody. A writer is dying to have his or her work read with complete attention. And here is this editor person, and the one thing they have done is they have paid full attention to your work, which is very gratifying.”
• An editor may act more like an agent or a music producer. Some editors will work closely with writers to help them determine career steps, going so far as to advise on what sort of book to write next. Others, like Raymond Carver’s editor Gordon Lish, will manipulate the original manuscript so much that their role becomes something more collaborative, or even borderline Svengali-like, as with music producers.
