Philip Payne tells me that CUP has authorized him to make available for free download his recent article "1 Tim 2.12 and the Use of ουδε to Combine Two Elements to Express a Single Idea" New Testament Studies 54(2008): 235-253 on his homepage here (where you will find other articles too).
Update:: Philip tells me tht a more detailed form of the paper read at SBL (which I recently blogged about) is accepted for publication with the other papers read at a Colloquium on Codex Vaticanus B in Geneva, Switzerland, along with the three essays currently only available in the Prolegomena volume of the Codex Vaticanus B facsimile. His new article is forthcoming as Philip B. Payne and Paul Canart, "'Umlauts' Matching the Original Ink of Codex Vaticanus: Do they Mark the Location of Textual Variants?" pages 191-213 in Patrick Andrist, ed., Le manuscrit B de la Bible (Vaticanus gr. 1209): Introduction au facsimilé, Actes du Colloque de Genève (11 juin 2001), contributions supplémentaires. Prahins, Switzerland: Éditions du Zèbre, 2009. Personally I remember that it was rather difficult to get hold of books from this publisher (e.g., they would not accept credit card payment), but I hope it will be easier in the future.
Moreover, Payne's other area which he has been researching for the past 35 years is forthcoming as Philip B. Payne, Man & Woman: One in Christ (Grand Rapids, Mich.: Zondervan, 2009) prior to the SBL.
