Publishing houses are more relevant than ever in the digital era, says Ursula Mackenzie, chair of the U.K. Trade Publishers Council. Responding to an article suggesting that publishers "now appear frozen in the headlights of the onrushing digital revolution", she says most major publishing houses have long been planning and investing in their digital divisions. "While some authors may prefer to publish and market their own work, many want the whole package offered by a publisher: editorial input; marketing and publicity expertise; first-class sales contacts and proper remuneration." "The demand for print works remains very strong."
