Particularly a problem with article level data.
Will make the experience as a whole better for the end
16. Rethink Facet Presentation
Add clustering framework to facilitate automatic tag
May link together articles, books, and data-sets that the

Should prove very useful with full text data.
User specific ranking
Further develop system and statistics tools
The hybrid library: from the users perspective
