Editing is an invisible art where the very best work goes undetected. Editors strive to create books that are enlightening, seamless, and pleasurable to read, all while giving credit to the author. This makes it all the more difficult to truly understand the range of roles they inhabit while shepherding a project from concept to publication. In What Editors Do, Peter Ginna gathers essays from twenty-seven leading figures in book publishing about their work. Representing both large houses and small, and encompassing trade, textbook, academic, and children's publishing, the contributors make the case for why editing remains a vital function to writers and readers everywhere. Ironically for an industry built on words, there has been a scarcity of written guidance on how to actually approach the work of editing. This book will serve as a compendium of professional advice and will be a resource both for those entering the profession (or already in it) and for those outside publishing who seek an understanding of it. It sheds light on how editors acquire books, what constitutes a strong author-editor relationship, and the editor's vital role at each stage of the publishing process a role that extends far beyond marking up the author's text. This collection treats editing as both art and craft, and also as a career. It explores how editors balance passion against the economic realities of publishing. What Editors Do shows why, in the face of a rapidly changing publishing landscape, editors are more important than ever.
