Hi /e/

I'm trying to complete my ishikei (niseMIDIdoronokai) doujin collection (i mean getting the originals, not downloading the scans).

I'm missing at least three or four I think. I was wondering if you knew a site listing them all so I can check which one I have.

I used to live in Japan and being able to find them easily, but now I'm back in France it gets a lot more complicated.

Thanks in advance, and for those who don't know, check him out, he's one of the best authors I know.
