Feedster has come out with a job search tool where users can search for a job and then subscribe to the feed for that search. I put in a search for “librarian” and there weren’t too many good, current, or relevant results. Perhaps it would be a better tool in searching under other fields (business and technology are the most obvious). The Feedster job search is still a little buggy (it’s in beta), so perhaps it will become more useful to librarians in the future.
