Toiya, yes, that anthology, Magical Realist Fiction, is a keeper. I tend toward looser definitions of MR, so I found the story selection in that anthology interesting and justifiable. And I think that sometimes there are works which are wholly MR and some which are only peripherally so, but that doesn't bother me much. In fact, I think the comment made here earlier, about MR being one thing to the genre readership and another thing to the academic sector is right on the money. Me, I think it's great that a type of writing can dodge definition.
Pigeonholing seems only to serve the marketing crowd.
The poll is right down there. Also, have you thought about Katherine Vaz. She's from The Azores, so not Latin American, but her work is strong and filled with similar influences. Kathleen Alcala's books are wonderful. Great discussion as usual.
