‘Burn the catalog’ “Electronic catalogs, wherever you go in the academic world, have become a horrible crazy-quilt assemblage of incompatible interfaces and vendor-constrained listings. Working through […] a relatively small collection, you still have to navigate at least five completely different interfaces for searching. Historical epochs of data collection and cataloguing lie indigestibly atop one another.” Tim Burke, Swarthmore “I’m to the point where I think we’d be better off to just utterly erase our existing academic catalogs and forget about backwards-compatibility, lock all the vendors and librarians and scholars together in a room, and make them hammer out electronic research tools that are Amazon-plus, Amazon without the intent to sell books but with the intent of guiding users of all kinds to the books and articles and materials that they ought to find, a catalog that is a partner rather than an obstacle in the making and tracking of knowledge.” Tim Burke, Swarthmore
So … • We need to find better ways • of leveraging the accumulated library investment in knowledge organization systems • of demonstrating their value • and of releasing their value in a web environment. • (OCLC Research activities)

Some other examples • Query routing (e.g. QuestionPoint) • Document routing (e.g e-prints UK)
So … • Libraries need to manage many types of objects – some of which have subject attributes • We will increasingly treat vocabularies and terms as resources in their own right • Workflow integration becomes more important – services need to be available where they are needed • Metadata creation • Searching … • Data exchange and terminology services
Manage many objects … Then: ‘information assets’ were primary objects of interest. Subjects, etc, were seen as attributes of assets. Systems built to reflect this. Now: We manage multiple objects, their representations and relationships: Assets Works; manifestations; copies Rights Collections Services Terms Concepts Names Places Users …

The past is another country .. • Need to think differently – using terminologies as resources in a distributed network environment calls forward different way of thinking • Making functionality available within multiple workflows • Available through human and machine interfaces
