Apple have just updated their Pages word processing application to enable you to export your publication in ePub format.
The ePub format is a standard e-book format that works within Apple’s iBooks apps on the iPad and the iPhone.
It is also works on many other e-book readers, though not on Amazon’s Kindle!
Apple have released some guidance and help on choosing between ePub and PDF.
There are other ways of creating ePub publications, but if you already have and are familiar with Pages then it does give you a very easy way to create an ePub e-book.
There are many different e-book formats which makes life challenging for anyone who wants to create e-books or resources in an e-book format for their learners.
