So there was this journal called The Monad.Reader. I found their blog here: <themonadreader.wordpress.com>. There are some PDF files still available, but many other links have died. It seems there was a source repository on <code.haskell.org> and some privately hosted forks as well, but the links no longer work. And this blog only covers issues 14β26. I found a few of the older issues as PDF files here and there, but not all of them.
Has someone a clone of the source repository? Could you upload an archive or something?
