There seems to be something half-way between beta-reading and development editing. I think it’s right for many new writers — I’m just finishing my first book, and was not about to pay a real development editor, but beta readers weren’t engaged enough (especially friends unwilling to point out the negatives). But it this kind of editing doesn’t really have a clear name.
If you’re a first-time author and have never hired an editor before, I would not recommend hiring an editor without first getting a sample edit. An editor can have a great resume and speak eloquently on the phone, but the real test of their skills is how they edit your book, and the sample edit is a quick, free way to find out. It’s standard for a freelance editor to offer a free sample edit unless they are exceptionally well-known.
I’d add that for UK writers, the Society for Editors and Proofreaders (SfEP) Directory is the best place to search for editorial professionals. Each editor has been vetted for professional competence through the Society (you have to be assessed to become a Professional Member or Advanced Professional Member), so it’s a pretty trustworthy source: http://www.sfep.org.uk/directory/directory.asp
Hi Sean, as an editor I run permissions for authors. It’s a case of contacting each right-owner (author or publisher) where the quotes are not deemed public domain, and provide them with context for approval. You can do this yourself or I’d be happy to quote for the work, if you’d like to contact me directly? My email address is email@example.com.
I cannot speak for all editors, of course, but I know I and many of us would be open to editing just part of your book at first, say, a particular chapter or two that you sense needs a lot of work. That is often enough to show you mechanical errors that you tend to make repeatedly. You can then go through the entire manuscript yourself looking for as many of the same kind of errors as possible. You will sharpen your basic writing skills in the process, and it will pay off in all future projects.
