From the start, I'm not looking for where I can download an author's stuff. I'm looking for where and when his stuff was published, what magazine I can find his stuff in.

I have several collections by Chunrouzan. One thing I noticed was that Waisetsu Ehon is the only one he did where he actually included the magazine and issue each work was published in. All the others have just the names. From Waisetsu Ehon to the present, he seems to have been publishing in Comic Aun. I've obtained a few older issues from 2007, around the time an older work, Otomodachi, was done, though, and I can't find a single piece. My main question then is where were the pieces in Friend(Otomodachi) and other Chunrouzan works published?
