Goodreads Librarians Group discussion

Hi, it's my first time when I've come across a book record that shouldn't be here. The description says that is available via subscription to a newsletter and I can't find any other place where it can be read. It is the only edition, it has no ISBN or ASIN. Should I mark it as deleted or invalid?

Thank you for your answer. I've marked it invalid.

It has been added by the author herself. I've already talked to her as I was completing her request for this series. She wasn't aware that it was against the rules.

I'll remember this. Would it be okay if I left it or should I remove it?

Done, thanks :)
