Encyclopedia fans rejoice! World Book expanded its mobile licensing program to make a lot more of its content available to mobile application developers and distributors. Now, third-party apps can use factoids from more than 90 World Book titles. They'll also have access to a bunch of datasets that can be customized and integrated into all sorts of digital applications, including games. Dataset topics include history, geography, science, literature, art, music, biography and general reference along with an image dataset with more than 20,000 illustrations, diagrams, graphs and maps.

The first mobile developer to take advantage of the newly available content is Mobifusion, which is publishing children's titles under the World Book Mobile imprint, "Baby's First Book" and "World of Animals."
