With the role of libraries evolving from warehousing data sources to controlling the dissemination of information sources, A&I (abstracting and indexing) information services must also evolve and play an equally important and challenging role. With over forty years of A&I publishing experience, CSA (formerly Cambridge Scientific Abstracts) has adapted A&I publishing methods to new technologies and Web-based publishing. The editorial basics of producing A&I journals and databases are unchanged; however, new production technologies, such as electronic feeds between primary and secondary publishers, electronic directory services, and machine-aided indexing, can provide efficiencies. Once just roadmaps pointing to information, A&I services are now conduits delivering information directly to the user. Serials Review 2003; 29:221–223.
