iBooks are eBooks available on iPads and iPhones that have the potential to be used as interactive textbooks in education. Key features of iBooks include being easy to download, manipulate, and search with keywords. Text can be highlighted and notes embedded while a touch-based dictionary is available. However, current limitations include a limited availability of textbooks, large file sizes consuming memory, and expense without the ability to resell. Potential developments could see teachers authoring their own iBooks, though issues around reliability, copyright and internet dependence remain.
