"In an era of computing dominated by the World Wide Web, technology referred to as Web services stands as a key one for allowing computers to communicate machine to machine, program to program....Web services make it easy to connect all types of computer applications to each other. As you will see throughout this report, Web services deliver a foundation of interoperability greatly needed in a world where computer services and digital information exist in many different forms and flavors."

"If, in the future, libraries want to be isolated islands in the ocean of content and information, they can ignore Web services. But because much of what libraries do centers on providing information to library clientele and because information is increasingly more electronic—which causes libraries to overlap with many other organizations in the information sphere—it is necessary for libraries to cooperate and interact with a broad set of other organizations and their technical infrastructures. Web services provide mechanisms that allow libraries to expand their services in many important ways."
