I believe that paid-for secondary services like Chemical Abstracts *will* have a place in the new world of OA. I am not convinced that give-away software from OAI or wherever will do the whole job of search and navigation through the literature. However, Stevan has always said that his arguments concern the primary research literature alone, so I guess he will have no problem with CA and its equivalents in other disciplines. Like all other legitimate toll-access sections of the publishing industry, they will survive if they are useful and users perceive that the cost-benefit analysis favours their purchase. University libraries contain many things other than research journals, and those other things will continue to be toll-access.
