There is a new website (web 2.0 tool) called Liszen Trends that facilitates posting of library news (mostly via blogs) and voting less than 24 hours after I wished for a digg-like tool for library literature. So I didn't quite get my wish, since the topics sometimes discuss professional books but that is a review ON a blog.
What I want is to be able to tag and vote on both the Old Literature and the New since both are information sources for professionals and, believe it or not, the Old has good stuffs.
