In a recent thread of mine (this one), no answer has been provided yet. To give a short outline: I am basically concerned for the issue to produce n.d. for citations and bibliography items when no date is given. Apparently it seems impossible because of a bug but I do not have the expertise to tell if that is indeed the case.
Hence I am wondering if I could just comment again to ask for more from the previous commentators? Or is there another guideline for this? If so, a link would be appreciated.
