The World‐Wide Web and Z39.50: which way for libraries?
Finbarr Joy, Robin Murray · VINE · 1995
The function of the World‐Wide Web, like that of Z39.50, is to offer access to networked information; and the client/server architectures of the two systems might appear similar. So why should libraries need both? The answer lies in the WWW's lack of support for the advanced search, retrieval and management facilities that are expected of modern OPACs — and that are also offered by Z39.50. Much current research, therefore, is involved in developing hybrid WWW/Z39.50 services.
