Open Road has partnered with HowStuffWorks to create a line of e-books drawn from the Web site's most popular content, starting with The End of the World, a book that explores doomsday prophecies and the demise of the world as we know it, and How to Survive the End of the World, a comical and practical apocalypse survival book. First titles will be available this month.

"This launch marks the start of a full range of e-books that we are developing based on the HowStuffWorks brand and our popular podcasts," added Conal Byrne, v-p of digital media at Discovery Communications & GM of HowStuffWorks. "Discovery's new partnership with Open Road allows us to fulfill a growing interest from our readers for our high-quality content where they want it."
