Writing a story takes blood, sweat, and tears, and the process of revising one’s own work takes time and dedication. All this hard work culminates in a promising manuscript, but in order to achieve the most success, a manuscript needs the attention of a professional editor. To receive the best editing, it’s important to know what to ask for—and that requires knowing the levels of editing offered.
Ultimately, each kind of editing can mean different things to different editors. But even when you have the lines between the various types of editing more clearly defined, certain styles of editing can bleed over between types and others cannot. It all depends on timing and the needs of the manuscript or publishing house.
