I just added ‘Politics on the Edge’ via the ISBN 9781787335141 on Book Connect. It came up with the correct cover and book but says Unknown Author. I have corrected that in my collection manually but thought I would let you know in case it’s a recurrent problem.
Looks like several sources on the web also have this book marked as “Unknown Author” as the actual author.
I’ve now changed it to Rory Stewart in our Core online database.
You can also report errors from Core: click the book, then click the little 3 dot icon above the book details, then click “Submit to Core” and you can report problems/submit fixes. Or you can post in the “Core | Errors” forum here (where I’ve just moved your topic to!)
Thanks
