In the early 1980s, Luis Alvarez and his colleagues added a new dimension to Darwin's theory of evolution. With evidence from studies of the earth's crust between the cretacious and tertiary layers, they postulated that the traditional slow, gradual mutation of species over eons was also punctuated with occasional major changes, often catastrophic, that caused leaps in evolution in relatively short “moments” of history. The extinction of the dinosaurs and half the other animal species alive between the cretacious and tertiary periods of earth's history was one such momentous change, forever altering the evolution of animal species.

To provide coverage and insights about the annual meeting of the AAAS where this year's theme was “Science and Technology for Sustainable Well‐Being.”

Environmental scan of annual national meeting. Of particular interest due to the range of backgrounds different attendees from all avenues of the scientific community.

Sustainable well being has wide applications in different arenas but the informatics component was not as strong as at past conferences.

Much of the conference focused on intersections of theory and application and new ways of responding to sustainability. Particularly strong in the physical sciences.

Provides information of value to information professionals.

The UK Office for Library and Information Networking are engaged in a wide range of work in the area of metadata, in cooperation with various partners. Projects on metadata for Internet resource discovery, interoperability and digital preservation all point to the continuing need for something like traditional library services to organise, access and preserve networked information.

This special “theme” issue of Library Hi Tech is devoted to Open Systems Interconnection. The editor is Ray Denenberg, of the Library of Congress. Eleven articles cover the basic OSI platform, applications, support areas, and implementation. The basic OSI platform consists of protocols for the seven layers, including support for file transfer and message handling. Three articles describe network applications and the corresponding OSI services and protocols. “Information Retrieval as a Network Application” describes the ANSI Z39.50 protocol. Another article describes the interlibrary loan protocol, which incorporates the sequences of messages that occur in distributed interlibrary loan transactions. An article about electronic data interchange describes the edi conceptual model being developed by ISO, and its relationship to OSI. Network management and directory services are two of the most important OSI support areas; individual articles cover these two topics. Implementation topics include profiles, testing, and products.
