A review is made of research in the design and use of languages for computer programming, with emphasis on one of its specialized applications, information retrieval, and on the end‐user directly interacting with the computer. It is shown that we lack the criteria for determining what is the best fit of a language to a particular user, although some research has suggested that there is a means by which this can be done, offering the users a wide range of language choice and using the computer as a means of helping him learn and adapt to the language.

We have conducted a study of academic faculty use of databases for research, their need for evaluative guides to databases, and the appropriateness of currently‐available guides. Although the response rate was low (19%), the follow‐up survey suggested only a minimal non‐response bias. Our findings suggest that academic faculty are typically unaware of the range of databases available and few recognize the need for databases in research. Of those faculty who do use databases, most delegate the searching to a librarian or an assistant, rather than performing the searches themselves. We identified thirty‐nine database guides; these tend to be descriptive rather than evaluative.

This article provides a broad overview of telecommunications and network‐related technologies. Topics covered include identification and review of network elements, analog and digital signals, synchronous and asynchronous transmission formats, transmission media and equipment, transmission techniques and characteristics, multiplexing, network types, access technologies, network architectures and topologies, local‐area network technologies and attributes, protocols and protocol issues, gateways, internetworking, local networking alternatives, equipment certification, and various aspects of network management. It is intended to provide the practicing professional in the field of library and information science with a broad, up‐to‐date technical review that might serve to support and facilitate further investigation of current developments in networks and networking. Although the broad range of topics is not treated in depth, numerous references are provided for further investigation.

This paper reviews the history of separate online system interfaces, leading to efforts to develop expert systems for searching databases, particularly for end users, and introduces the research in such expert systems. Appended is a bibliography of sources on interfaces and expert systems for online retrieval.

On‐line update combines a bibliography of recent on‐line articles with a search example from a data base producer or an on‐line system vendor.
