A very interesting post today by Jill Walker on institutional repositories, their benefits, and the ways that they fall short of the ideal networked publication archive she'd like. There's of course a key difference between the repository and the kind of publishing environment that we're imagining -- the repository is a somewhat secondary storage facility for the publications of a cluster of scholars, rather than a primary locus of publishing in and of itself -- but I think there's still much to consider in the issues that Jill raises.
