NEW YORK (AP) -- Apple says its launching a new version of its iBooks software, tailored to present vivid, interactive textbooks for elementary and high school students on the iPads.

IBooks 2 will be able to display books with videos and other interactive features.

It's not clear how Apple plans to get it front of students, however, since textbooks are subject to lengthy approval processes by states. Also, few students have iPads, which start at $499.

Apple is revealing the software at an event at the Guggenheim Museum in New York.
