Discusses issues relating to recent introductions of CD-ROM technologies in libraries and considerations that have motivated libraries to choose networking CD-ROMs over the standalone approach. Factors discussed include cost effectiveness, the flexibility of the networking approach, and performance considerations. A glossary of terms is provided.…

Presents suggestions from online searchers for using online services. Topics discussed include decreasing costs by using less expensive files; modifying searches on Dialog; use of controlled vocabularies and free text; using a variety of databases; the importance of search intermediaries understanding the topic; and patent searching. (LRW)

Summarizes various linguistic approaches proposed for document analysis in information retrieval environments. Topics discussed include syntactic analysis; use of machine-readable dictionary information; knowledge base construction; the PLNLP English Grammar (PEG) system; phrase normalization; and statistical and syntactic phrase evaluation used…

Describes specific techniques for using the MAP command for business searches on DIALOG that use more than one file. Limits of the MAPping function are discussed, and modification of these techniques for application to other databases and systems is explained. (Four references) (LRW)

The first of two articles describes how a team effort by computing centers and academic libraries could aid faculty in the organization of their personal databases. The second provides an overview of the academic library automation market, identifying vendors active in the market and trends of recent years. (CLB)

Contends that, in developing countries, attention must be paid to the quality of data going into computer-based information management systems; otherwise implementation of the system may provide only a deceptively systematic procedure for making random decisions. Examines errors, assumptions, inabilities, and omissions that threaten data quality…

Discusses the use of optical character recognition (OCR) technology to produce an ASCII text database. A tutorial on digital scanning and OCR is provided, and a systems integration project which used the Calera CDP-3000XF scanner and text retrieval software to construct a database of dissertations at George Mason University is described. (four…

Discusses the wide variety of installation standards currently maintained by publishers of CD-ROM databases and the problems this can cause for users. Hardware and software requirements of various CD-ROM databases intended for use on IBM personal computers and compatibles are described. (five references) (CLB)
