Combining and merging book editions/duplicate entry

[B]

* Combining and merging book editions.

Hi,
I’ve just come across what seems to be a duplicate listing for the following book:

De la psychanalyse à l'astrologie by André Barbault (1961)
ISBN-13: 978-2020026826
ISBN-10: 2020026821
200 pages, published by SEUIL on 1 November 1961
French
https://www.goodreads.com/book/show/7...

Suspected duplicate listing:
https://www.goodreads.com/book/show/1...

Unsure if I have posted the topic correctly or if it’s in the right folder.
Thanks!

[Martin]

Now combined.
I don't think they are the same edition as a 1961 edition cannot have an ISBN, that must be an incorrect date.
