When an ebook with annotations is removed from Ebook Central the ebook stays on the patron’s bookshelf. The patron may export notes saved for that ebook. If the library regains access to the book, they will be able to annotate in the Online Reader again as well.

Below is a screenshot of how an ebook would look on the bookshelf after it becomes unavailable on the Ebook Central platform.

Text highlighted by the patron is not included in the exported notes.
