While non-verbal markings, including evidence of readers’ attention and engagement via asterisks or characters, are not marginalia according to Jackson, we do consider this repertoire of signs and symbols an important form of annotation (particularly among digital texts and contexts).
Now I'm wondering how to effectuate an asterisk more simply on digital platforms.
- simply doesn't quite do it in an overlay system like hypothes.is though their highlight set up does quite well.
Perhaps bookbook.pubpub's annotation indicator could act as an asterisk whether the note field is empty or not?
