In the iBooks app on the iPad the user has control over the justification. Well, that is, by default justification is turned on. Users can turn that off - but they probably don't! ‘cos they don‘t know where to find it.
How can eBook designers get the kind of alignment they prefer, and make the eBook stay like that?
My eBook eBook Typography for Flowable eBooks has been in the iBooks store for a couple of weeks, but I wasn't happy with a couple of issues, so I have uploaded a new version to the store.
It occurs to me, that eBooks can be updated (to fix stylistic problems), and rather than this being an entirely new edition (as it would be in pBook), this is simply a small update and could be handled in the same way that software is updated. On my title page, I have an aside that displays the version number.
