Thank you!!

Edit: additional duplicate found: https://www.goodreads.com/book/show/5... (has ISBN-13, the other entry has the ISBN-10)

Then please combine with https://www.goodreads.com/book/show/5... and https://www.goodreads.com/book/show/5... (I'm trying to combine the last one myself but I've been getting an error message for a while now)

Done. Excellent sleuthing job in finding that truncated ISBN to match! :)
