CD-ROM data storage technology: Benefits and limitations in document publication

Optical data storage advances and compact disc market acceptance have led to the development of a new mass storage medium, CD-ROM (Compact Disc—Read Only Memory). This article provides a brief overview of the technology; lists the production processes associated with it; outlines its advantages and disadvantages; and provides current costs and storage equivalents. The article continues with an analysis of specific benefits and practical limitations of CD-ROM technology in documentation. Jay E. Gillette currently is on the staff of Bellcore’s Information Networking Institute, a joint program with Carnegie Mellon University. Previously, he was a senior technical planner in Information Technology, and served with Virginia Meade as project manager for Bellcore’s first CD-ROM product.

Development of a Model for Cataloging,Circulation, and Housing CD-ROMs

As more and more incoming freshmen arrive on campus with computers equipped with CD-ROM drives, faculty incorporate data from CD-ROM products into assignments, and library materials arrive accompanied by software on CD-ROM, librarians need a model for cataloging, circulating, and shelving these materials. This article offers a model, one that bases cataloging, circulating, and housing decisions on three factors: the type of data on a CDROM, who will use the data, and how will they use it.     

The Challenge of CD-ROMs for Libraries

CD-ROM technology is revolutionary. Becase of CD-ROM technology, libraries can now buy large number and variety of databases. The challenge to libraries is to provide access to CD-ROMs and related software. By setting up CD-ROM workstations and applying conventional library principals to organization of the disks themselves, libraries can give users easy access. The payoff is that we will be making vast new resources available to users.

The Influences of CD-ROM Databases on Information Selection

The advent of the CD-ROM database has brought a new era of computerization to libraries. Increased searching abilities allow both users and librarians to access immense quantities of information quickly and easily. However, in our euphoria we must not forget to see the limitations of these products. Students have embraced the new technology of the CD-ROM database as can be observed in numerous user preference surveys. However, if we do not educate these users about all sources of information and the limitations of CDs we may be doing them a disservice. Selection of an indexing source may be based on ease of use at the expense of appropriateness of coverage. Some of the impacts of the CD-ROM technology and its use are examined in this study, including the impact on journal usage as it relates to indexing coverage.     

New technology products: How to separate opportunities from potential disasters

In few areas are the risks and opportunities for publishers as great as they are in new technology products. Richard Johnson discusses the opportunities publishers have in expanding into software, audiotapes, online databases, CD-ROM, and video. He reviews the history of publishers’ involvement in these fields, what has not worked and why, what has worked, and the costs. He also offers rules of thumb for each product and outlines what is needed to succeed in any new technology venture. Richard O. Johnson’s consulting practice provides advice, problem solving, and implementation in the areas of technology, strategy, and business development. His background includes VP-Corporate Development at John Wiley & Sons, VP-Planning and Business Development for two subsidiaries of Allied-Signal Corp. and several years of venture capital startups for Exxon Enterprises.

The effect of CD-ROM MEDLINE on online end-user and mediated searching: a follow-up study

Indiana University School of Medicine Library (IUSML) has traditionally been a high volume searching institution. The dramatic effect of CD-ROM on online end-user searching and the negligible effect on mediated searching was reported in an earlier study. This follow-up study reveals that the proportion of mediated searching has been drastically reduced from 94% in 1986/87 to 39% as of November 1989. Mediated searches are declining in absolute numbers as well. End-user searching, by contrast, has increased by 54% percent over the previous year. A related trend is the increased use of CD-ROM by the librarian as an alternative to mediated online searching. These trends are expected to continue as IUSML expands its CD-ROM operation to include other databases. As mediated searching declines, the librarian's role will increasingly include end-user training.

NEW CHALLENGES FOR LIBRARY ACQUISITIONS

Current financial reporting practices for library expenditures generally exclude costs/services which are "contributed" to the library from beyond its budget by other units within the larger parent institution (whether it be a city, school or university). This article reports a specific cost case study analysis of a particular university library, detailing the costs of providing library services to users. A "full cost" discussion would need to include several non-expenditure costs. This report does briefly describe such economic cost categories but the specific case addresses only financial accounting costs. The categories, and techniques of analysis as well as resulting observations, are applicable for any manager seeking the most realistic detailing of the costs incurred in operating a library.
