Why not consider it essentially the same as a magazine article? The analogy is particularly apt on USElessNET, where everything is an "article", but I can see that extended to LISTSERV mailing lists, too. Now if it's a personal letter sent from me to you, you'd probably want to cite it that way (with appropriate notation that it was an e-mail, rather than USnail, letter), but list messages might go like this: Brindle, Nathan. "Re: Net message citation" (December 6, 1994, 18:25:27 EST: e-mail posting to [log in to unmask]), 2-6. My thought is that the time would be critical--I might respond more than once to messages with that subject heading. The last item would be the specific lines of the message quoted, in the example, lines 2-6. It might even be appropriate to quote my Internet address. Your mileage may vary. My Turabian is buried in a box somewhere, waiting to be moved. :) But remember that the point of a citation is to allow the reader to find your source if he/she feels so moved. The information above would make it quite easy to find the cited message in an LDBASE search. Nathan
