The Editorial Department?! / Lektorat?!
Writers have never been perfect at grammar or spelling: they didn’t need to be, they could rely on their editors and proof-readers to knock their text into shape. These days, many people, including publishing staff, think the spell-checker on their computer does the job. But, even if it’s properly used, it still requires the writer, for his or her part, to have enough knowledge to accept or reject any changes it makes. Disregard this requirement and classic errors creep in: an automatic ‘search and replace’ correction can give you ‘who’ where it ought to be ‘whom’.
