The excerpt, and discussion of it, is on Compuserve here. There is also an earlier discussion about this story on Compuserve, here, if you haven't already seen it.
I believe the anthology in which this story will appear is called DOWN THESE STRANGE STREETS, but that is all the information I have about it at this point. As soon as I find out more specifics, I will post them here.
Please keep in mind that I am (mostly) an excerpt-avoider. If you want to discuss the specifics of this or any other excerpt from one of Diana's unpublished books or stories, please post on Compuserve or the LOL Excerpt Board. Thanks.
