  2. Why Another OAI Registry • Difficulty finding relevant OAI repositories to harvest, especially in selecting individual sets within a repository • Other questions: • Which repositories are aggregating other repositories? • How big are individual repositories? • How to find new repositories as they come online? • What is the state of the OAI world? • Enable other meta services ECDL 2004, Bath, U.K.
