The document discusses how libraries are moving away from traditional print collections (ponds) and toward providing on-demand access to digital information sources (rivers). It notes that reference services, physical collections, and the OPAC are becoming less important as discovery and access have moved online. The future of libraries is predicted to involve smaller local print collections but access to large public digital collections, fewer subscriptions in favor of pay-per-view article access, and libraries focusing more on brokering access rather than maintaining extensive local collections. Publishers are also predicted to move away from bundling journals in large packages toward an a la carte, transaction-based model.
