@emucat - If this thread is the main thread for the ABJBC then it really needs a list of all the books that have already been read at that level. So far there have been:
にゃんにゃん - you don’t yet have a link in the OP to this one
なぜ？どして？ - this one you have a link to
Yotsuba - this originated from the original bookclub but then took on a life of its own, and we are about to start vol.7, the ABJBC OP really needs a link to the Yotsuba meta-thread
Like I say, I think the ABJBC is a great idea, so I hope this helps!
