11. Did You Know About ... ePub?
The success this year of the Apple iPad has brought the ePub standard to new prominence, as the format for electronic books, used by the excellent iBooks program. ePub is an open standard for ebooks owned by the International Digital Publishing Forum (IDPF). The format is really rather simple: it is a zip archive of HTML files, just the same ones you used for the web, with associated CSS files, images etc, and a set of metadata files written in XML which provide information like a table of contents, and reading order.
