Digital editions of books are rapidly gaining popularity. While some people still find it preferable to use hard-copy, more and more people move to eBooks in favour of added functionality and usability. When it comes to a book you own, it is nice to be able to commit your thoughts on to it. Highlighting, scribbling, commenting or making notes on your copy allows a more personalised feel to your books. And it makes reference a lot easier. Unlike in printed books, the original text is not ruined by user edits on a soft-copy. Such data introduced by the user are referred to as "annotations". They are actually an overlay of information over the book print.
