This Helping You Buy survey is the next in an annual series of surveys that have been compiled by Pamela Cibbarelli in past years. This bird's-eye view should serve to both highlight some general distinctions and to underscore the commodified similarities of a wide range of library automation systems.

Discussion of the potential effects of fiber optic-based communication technology on information networks and systems design highlights library automation. Topics discussed include computers and telecommunications systems, the importance of information in national economies, microcomputers, local area networks (LANs), national computer networks,…

Reports on the third national conference of the American Library Association's Library and Information Technology Association, which was held September 13-16, 1992, in Denver, Colorado. Program highlights are summarized, including virtual communities, virtual reality, the electronic library, artificial intelligence and expert-systems, navigating…

With the introduction of the library's OPAC (Online Public Access Catalog), CD-ROMs, the Internet, and OhioLINK, the University of Toledo library is faced with technological, instructional, and other challenges. The main challenge is the lack of a mediated classroom for group instruction. Current paper-based teaching methods do not always allow…

Describes the layered model of Open Systems Interconnection (OSI); summarizes the three upper and lower layers; and discusses data communications standards associated with specific layers. Architectural concepts are explored, including hierarchy and abstraction, levels of dialogue, internetworking, and end-to-end communication. OSI is compared…

Discusses the uses of microcomputers in libraries. Highlights include selecting hardware and software; providing microcomputers for public use; using microcomputers to access larger systems; the use of general purpose software, including desktop publishing; computer networks; library specific software; and the future of microcomputers in…

Discusses the impact of information technology requirements on the costs of electronic libraries. Addresses key questions concerning hardware, software and network installation and upgrades and provides strategies for dealing with the needs for continuous funding and long-term financing that are essential for keeping up with the requirements of…

Explains how the Directory Service (CCITT X.500/ISO 9594) became an international standard in response to the difficulties of keeping data on information network users current and accessible. Uses of X.500 are described, a technical overview is provided, its functions and protocols are assessed, and directory projects and products are discussed.…

Management of heterogeneous networks is complicated by the persistence of proprietary management schemes. The need for integration of network management capabilities is pressing. The International Organization for Standardization is developing standards for managing networks as part of the Open Systems Interconnection (OSI) effort. OSI management…

Reviews some of the projects and organizations concerned with promoting conformance and interoperability testing of Open Systems Interconnection (OSI) products and describes OSI products available from computer manufacturers and vendors. A list of references includes 57 articles that mention specific vendors and 11 general articles about OSI…

Presents an overview of projects aimed at identifying the impact and value of digital and networking technologies on the British Library's collection and services. Examines the way in which the issues of preparation, scanning, and storage have been dealt with, as well as general principles that can be drawn from these experiences. (AEF)

This bibliography brings together sources, through August 1991, on the National Research and Education Network (NREN) and related topics, including computer networks, databases, information technology, library automation, microcomputers, and online systems. Where possible, a brief biographical note on the author is included, and most of the…

Traces the evolution of Open Systems Interconnection (OSI) from its genesis in 1978 and provides an overview of the various categories of standards, international standards organizations, the scope of standards, and the notations used to designate both the standards groups and the actual standards. (SD)

Discusses how various Open Systems Interconnection (OSI) application layer protocols can be used together, along with the Presentation and Session protocols, to support the interconnection requirements of applications. Application layer protocol standards that are currently available or under development are reviewed, and the File, Transfer,…

The edi conceptual model is being developed to define common structures, services, and processes that syntax-specific standards like X12 and EDIFACT could adopt. Open Systems Interconnection (OSI) is of interest to edi because of its potential to help enable global interoperability across Electronic Data Interchange (EDI) functional groups. A…
