Adding new book(s) - Hanta Yo in Slovenian, multivolume

[Borut]

Hi!

Could some librarian add few books in Slovenian language please?
I'm talking about Hanta Yo:
https://www.goodreads.com/work/editio...
On link I provided it's version in one volume, but in Slovenian language there are four volumes:

* Title:Hanta jo I
* Author: Ruth Beebe Hill
* ISBN: -
* Publisher: Pomurska založba
* Publication date: 1983
* Format: Hardcover
* Number of pages: 493

* Title:Hanta jo II
* Author: Ruth Beebe Hill
* ISBN: -
* Publisher: Pomurska založba
* Publication date: 1983
* Format: Hardcover
* Number of pages: 228

* Title:Hanta jo III
* Author: Ruth Beebe Hill
* ISBN: -
* Publisher: Pomurska založba
* Publication date: 1983
* Format: Hardcover
* Number of pages: 332

* Title:Hanta jo IV
* Author: Ruth Beebe Hill
* ISBN: -
* Publisher: Pomurska založba
* Publication date: 1983
* Format: Hardcover
* Number of pages: 359

I've made "Hanta jo I" Slovenian edition in, but think it's wrong simce on provided link is only one volume edition and should be merged with one I asked for.

Thanks, Borut
