Following a recent iPad announcement, Encyclopaedia Britannica, Inc. announced today its trusted encyclopedia is now available as an iPhone App through the Apple App Store. The Encyclopaedia Britannica App gives the millions of iPhone users the ability to find information and explore subjects without compromise, anywhere at any time. iPhone users can feel confident that what they are searching for is accurate and provided by professional editors and expert contributors including former U.S. and international presidents, Nobel Laureates, scientists and other historical figures.

The app is free to download and comes with complimentary high-resolution images, maps, access to 100 free articles plus the first 100 words of every article, and the Britannica “link map.” For $1.99 a month, iPhone users can upgrade their app to include full access to all 80,000 articles in the Encyclopedia, the ability to download information to read offline, save and send articles, store favorites and search history and more. Android and Microsoft versions of the app are expected to follow in early 2012.

“Continuing to offer consumers more options, Encyclopaedia Britannica is giving iPhone users the ability to take one of the most trusted and authoritative resources with them whenever, wherever,” says Greg Barlow, Encyclopaedia Britannica’s senior vice president and chief marketing officer. “Whether at home or on-the-go, our world-class information is available on a fast, mobile platform.”
