If you’re an author on a budget, you might think that hiring a professional editor is an extra cost that you can do without. “I’m a great writer,” you might say to yourself, “and I spell-checked my manuscript, so I don’t need an editor.” This would be a big mistake. Even the most talented writers hire editors. (If it weren’t for the advice of his editor, F. Scott Fitzgerald might be best known today for writing a novel called Trimalchio in West Egg or The High-bouncing Lover.) But editors do more than just fix spelling errors—although they do that, too. There are different kinds of editors, and they can work with you at every stage in the publishing process.
