Marilyn Schwartz has incisively and thoroughly updated and expanded The Copyeditor's Handbook, adding best-practice advice on editorial ethics, accessibility, digital sources, plain language, ESL, and more. Amy Einsohn would be so pleased! Pair this rigorous yet amiable handbook with The Copyeditor's Workbook for a complete course in manuscript editing.--Carol Saller, author of The Subversive Copy Editor Marilyn Schwartz has crafted a worthy revision of this revered classic. Much here is new, taking us fully into the twenty-first century. Further thoughts and explication from both Amy Einsohn's posthumous notes and Schwartz's own experience are so skillfully woven in that Einsohn's voice continues to sing through.--Pm Weizenbaum, 2018 president of the Northwest Editors Guild The Copyeditor's Handbook remains the best guide for copyeditors. Marilyn Schwartz has done a thorough job of addressing the 'tectonic shifts' in editing, using Amy Einsohn's copious notes and her own deep experience. It's as though she read the minds of editing instructors everywhere when we've said, 'I wish Einsohn covered . . .'--Erin Brenner, owner of Right Touch Editing and former owner of Copyediting.com The fourth edition does the well-loved Amy Einsohn proud, especially with the new material covering digital editing, helpful software, and indie authors. Editors everywhere will greatly appreciate the editing code of ethics added at the end of chapter 1. Reading this book is the next best thing to having a good mentor.--Katharine O'Moore-Klopf, ELS, owner of KOK Edit
