I have noticed an article published in a peer-reviewed journal in which the author cites a draft paper posted by another person to academia.edu. The former gives the whole bibliographic information of the aforesaid draft (including the URL) at the exact place where it is cited, but does not mention that draft at all in the bibliography, even though she does give all other sources she has cited in the bibliography.
Does it mean that a draft paper can be cited but should not be included in the bibliography? If it does mean that, is this because it is not yet peer-reviewed? I am rather curious here.
(For those who need to know, the field is religious studies.)
