I would argue that our energy would be better spent thinking about the next generation library rather than the next generation opac. Is it just me, or does anyone else feel that the very idea of having a catalog as an important component of a library smacks of retrograde thinking? To my mind, in a clean-slate NG Library architecture, the library catalog should only exist as a facade that recognizes of the vanity of libraries and the people who fund them. I can think of no technical justification for library catalogs as we look forward. If not the next generation, then the next-next generation of libraries. The functions that exist today in library catalogs need to be pushed in two directions- toward the user on one hand, and towards global registries on the other. the other Eric -- Eric Hellman, Director OCLC Openly Informatics Division [log in to unmask] 2 Broad St., Suite 208 tel 1-973-509-7800 fax 1-734-468-6216 Bloomfield, NJ 07003 http://www.openly.com/1cate/ 1 Click Access To Everything
