The new issue of Publisher's Weekly has a couple of articles about fantasy and science fiction: "Fantasy Goes Literary" by Gwenda Bond and "Too Geeky for Its Own Good?" by Ron Hogan. (Thanks to Richard Nash for the tip.)
Update 4/4/06: Ron Hogan has posted outtakes from his article, with some interesting stuff from Lou Anders, David Hartwell, and others.
Also, be sure to check out Colleen Lindsay's great comment about publicity in the comments to this post.
