Part 1 The problem: the network information revolution; the role of standards in network information; a non-technical view of Z39.50; OSI vs. TCP/IP; responding to the revolution - becoming the library without walls; using IR as a basis for change. Part 2 Some solutions: a taxonomy of standards - why standardize?, types of network standards, common concepts, the OSI model - an overview; local area network standards - what is a LAN?, LAN models, IEEE 802.3 and ethernet, IEEE 802.5 - token ring, FDDI - fiber distributed data interface, discussion; internet standards - basic architecture, internet protocol (IP), transmission control protocol (TCP), user datagram protocol (UDP); OSI standards - physical layer standards, data link standards, HDLC, multilink procedure (MLP), network layer services, X.25, ISO IP, transport layer services, session layer services, presentation layer services, application layer services; common application protocols - electronic mail, simple mail transfer protocol (SMTP), message handling (X.400), file transfer, file transfer protocol (FTP), file transfer, access and management (FTAM), remote access (telnet); information retrieval - Z39.50 - Z39.50 models, Z39.50 PDUs, Z39.50 operation - an example.
