Editorial Niches began as part of Editing Canadian English, 3rd edition -- the style manual of Editors Canada. However, to keep the print edition a manageable size and price, the sections on editorial roles and requirements (chapter 12) and editorial niches (chapter 13) have now been published as this companion volume, using the same chapter numbering to preserve the link with the online edition. Chapter 12 explores key roles and requirements for editors today: Professional Editorial Standards (2009): the fundamentals of editing and standards for structural editing, stylistic editing, copy editing, and proofreading professional development fact checking indexing email etiquette software for editors Chapter 13 delves into a wide variety of editorial niches: online materials books corporations, not-for-profits, associations, and government educational materials academic materials poetry, plays, and screenplays cookbooks magazines science, technology, and medicine visual materials Whether you are a would-be, new or established editor, Editorial Niches offers a treasure trove of information by a team of seasoned editors who are experts in their field.
