It is best to annotate in the online reader and then export the annotations as they will go away once the loan period expires.
To annotate:
Delete Annotations:
In the Annotation Panel, highlight the ones to delete and click the trashcan icon.
In the Ebook, double-click on highlights and notes and click the trashcan icon.
Export Annotations:
Go to your Bookshelf.
Each Ebook will have four icon options. Select the last one with the three dots. Then select “Export Notes” in the dropdown menu. Note: any highlighted text will not be included in the export.
Annotations will be downloaded as a .txt file.
