Copyediting and developmental editing are two different steps in the editing process. Although both processes involve improving language, grammar and structure, the difference between them lies in the types of revisions that are made.
Copyediting: Copyediting focuses primarily on the language and grammar of a given text, as well as making sure the text flows nicely and reads effectively and clearly. This is done by looking for typos and grammatical errors, ensuring factual accuracy, and ensuring the text is consistent with any existing style guidelines. It also involves checking for accuracy and correct formatting of tables, figures, images, footnotes and references.
Developmental Editing: Developmental editing is a more in-depth process that involves reading the text as a whole and working with the author to improve the text’s structure, organization and overall readability. This might involve changing the order of paragraphs, adding or removing text, and offering advice and guidance on how to better communicate an idea. The focus is on strengthening content and improving the quality of the writing.
In some cases, the copyeditor and the developmental editor may be the same person; in others, the two roles may be carried out by different editors. It’s essential that both roles are conducted when working on a piece of writing, as each provides its own unique set of contributions to the overall outcome.
