The B-Club Visual Comic is a separate item from the book that fans commonly call the "B-Club Special" (I don't know if they are both technically B-Club specials though).
I believe that both of them contain short mangas. It would be nice to get either those manga, or the entire specials, translated. (Although who knows if the budget would allow for translation.)
There also seems to be another short manga from a different source (see http://stevethefish.net/life/life080.htm.
Also, I once tried to find the AD Police B-Club Special. I have seen no evidence that it exists, no ISBN, no picture of the cover, even though finding this information for the Crisis and Crash specials was trivial.
