Britannica has launched its Britannica Mobile iPhone Edition online encyclopedia for the iPhone. The web application features “tens of thousands of articles” covering all subjects, accessible through an iPhone- and iPod touch-friendly interface. It also offers full-text searching, thousands of high-resolution thumbnails that expand to full-size images, and page layouts optimized for cell phone bandwidth. “People today want information wherever they go,” said Dan Smith, senior vice president at Encyclopaedia Britannica. “They want to satisfy their curiosity the moment it’s aroused, whether they’re on a train, in a restaurant talking to friends, or watching a sunset on the beach. Now we can get answers to them in ways that weren’t possible before.” Britannica Mobile iPhone Edition can be accessed by visiting i.eb.com from an iPhone or iPod touch.
