Three books in Enid Blyton's St Clare's series that don't belong

[Sarah (is clearing her shelves)]

Hi all, there are three books by Pamela Cox included in Enid Blyton's St Clare's series. Although they continue the story with mostly the same characters I don't think they should be included in the original series. Can someone take out the Pamela Cox books for me or advise me how to do it myself? Thanks for your help.

Since the books that Pamela Cox wrote fill in the gaps in the Enid Blyton novels and aren't all direct sequels, I don't see any reason why they should be separated.

I just thought because they're not part of the original series, not by Enid Blyton, that they shouldn't be included.

This problem with this series has been discussed before. http://www.goodreads.com/topic/show/1... and http://www.goodreads.com/topic/show/9...
Based on those thread the three newer books can be part of the series but publication order would be better than chronological order.

Thanks for those links Renske. I read both conversations and I'm still confused. It seemed that both dicussions came to the consensus that the books should be listed in publication order rather than chronological order, but the St Clare's books are still listed in chronological order. Does that mean that you and I are going to be disappointed and they aren't going to be listed seperately?
