This report was commissioned in response to concerns expressed about the gap between institutional digital library initiatives and the products offered by library systems vendors. The study analyzes from the perspective of libraries the strategies, visions, and products that vendors of integrated library systems are offering as solutions. Case studies are provided of four different types of libraries that have installed commercially available systems to provide a snapshot of the extent to which these systems met the needs of the institutions. Vendor profiles are then offered for 12 companies, including a brief summary for each, and information on primary products and services, primary markets, overall strategy, product tools and features, adaptability to library needs, strategy for networked information, product development infrastructure, acquisitions and strategic partnerships, corporate organization and offices, and a financial statement.
