This document discusses RSS (Really Simple Syndication) and how libraries are using it. RSS allows content on the web to be parsed into XML files that can be read in news aggregators or readers. Libraries are promoting events, new databases, and selected links using RSS. Subscribing to library RSS feeds allows patrons to keep updated on new materials and services in an easy, time-saving way without having to visit websites individually. The document provides many examples of library RSS uses and guides patrons on how to find, subscribe to, and search RSS feeds.
