Apple changes system requirements for Author-produced titles
A change in the system requirements language for iBooks Author titles could mean that the next version of Author will support formatting for the iPhone and iPod touch. Until recently, Author-produced books came with a narrow disclaimer: "This book can only be viewed using iBooks 3.0 or later on an iPad. iOS 5.1 or later is required." Now, though, that language has loosened somewhat. "To view this book, you must have an iOS device with iBooks 3.0 or later and iOS 5.1 or later, or a Mac with iBooks 1.0 or later and OS X 10.9 or later," Apple writes.
Author already includes an option for reflowable portrait layouts, which should in theory make it easy to enable reading on smaller screens. Apple may simply be waiting for the release of iOS 7, and/or OS X Mavericks, the first version of OS X that will include a native iBooks reader. iOS 7 should arrive later this month; Mavericks will likely ship in either September or October.
