Abstract:

In a world awash with information, finding what you really want can be difficult. Any database or web index can deliver a set of results. But it's particularly difficult to highlight the most relevant 'stuff.' Web search engines such as Google and Yahoo try their best to recommend some items over others, and now libraries are trying to do this for their holdings.
