I want to buy his books but I can only find some of them online, all by different publishers. I would like to own the whole bibliography and if possible by one publisher (just so that it looks better in my shelf. Haha) I figured there should be a collection with several volumes.
I’d prefer it in English and from an online shop shipping to/within Europe. If you know of such a thing, please let me know. Thank you!
Edit: if you don’t have a shop link but the ISBN(s), it would help me too.
