Nick Luft has pointed out that all the research-based work on metadata may come to nought as commercial search engines go their own way and ignore it. As librarians and information professionals, we are eminently capable of evaluating and reviewing material and that we have translated those skills to the electronic age has been amply demonstrated. But I believe it is time we began to do more than create gateways and portals to small selections of ring-fenced quality material. Metadata may be slow in being accepted and used but it has a tremendous potential for resource location and assessment.
