Reading is not a dialogue between you and the author, but rather an expression from the text to your brain. When you annotate, your mind develops a contextual relationship with the document. This includes facts, criticisms, links to related documents or web links, better navigational cues, and more.
You can annotate your ebooks with a highlighter tool, comment tool, underlines, callout arrows, and much more. We’ll show you six EPUB readers for Android that let you annotate ebooks and export notes in different formats.
