This is not permitted. Our partner shops do not allow eBooks that are summaries of previously published works. There are several reasons for this:

- It can lead to legal problems with the original authors, which the shops want to avoid in advance.
- It can mislead readers when making a purchase
- Summaries of books are considered companion books and are not considered a product in their own right.

A workbook for your own book, in which only certain passages of the book are summarised again, is not a problem.
