Combine editions? Swedish speaker needed

[Jessica]

So I was adding some of the old books on my shelves to the Goodreads database, when I came across this book: Argwaan rondom Astrid
However, when I was trying to find out if the original book was already in the database or not, I had a bit of a problem because I don't speak Swedish.
Now, the original title of the book is 'Kulla-Barnen pa herrgarden', according to the book itself. But on the page of the author Martha Sandwall-Bergström there is no book with that title. There is however the book Kulla-Gulla på herrgården, which sounds very similar to me, but I have no idea if it's the same. It doesn't help that there is no synopsis I can put through google translate either.
So, I just added is as a different book for now, but if it's the same book, they need to be combined.

"Pa herrgarden" isn't Swedish, it should be "på herrgården". "Barnen" means "children", so unless there are two titles with almost the same titles, it's the same book. (And it seems that Gulla is the girl's nickname, short from Gunilla, so...)

Allright, that's what I thought. Thanks for the help. I'll combine them ^^
