Outlines the rationale and design of the Social and Organizational Life Data Archive (SOLDA), an on-line collection of survey and other statistical data relevant to research in the fields of management, organizational studies, industrial relations, marketing, and related social sciences. The database uses CD-ROM technology and the World Wide Web…

Introduces the multicharacter trie as an index structure that can improve the time needed for retrieving full-text materials stored on CD-ROMs. The advantages of this structure compared to other structures are described, and experimental results comparing it to the widely used B+ tree and other structures used for full-text retrieval are…

Compares pricing of seven CD-ROM-based public access catalog systems for libraries of diverse sizes and groupings. Other features of the systems are outlined in the broad areas of database preparation, indexing, database updates, hardware, information retrieval, library controlled elements, interlibrary loan, reports, user support, future…

Describes a menu-driven software system for searching CD-ROM databases that also unobtrusively gathers data on CD-ROM usage. The discussion covers the steps involved in creating a log file using DOS, tips for capturing user status, strategies for salvaging incomplete data, and types of CD-ROM usage analysis supported by these data. (three…

Describes the latest technology in videotape cassette systems and other magnetic storage devices and their possible effects on optical data disks. Highlights include Honeywell's Very Large Data Store (VLDS); Exabyte's tape cartridge storage system; standards for tape drives; and Masstor System's videotape cartridge system. (LRW)

Analyzes the currency of the information found on SilverPlatter's Medline CD-ROM. Results show that the currency of information can vary tremendously. Priority level, periodicity, and prior database were found to have a low but highly significant influence on currency. Six tables and nine figures show results. (Author/AEF)

Presents compact disc (CD) technology as the method of choice for data collection and knowledge distribution. Discusses four phases of the CD network storage application (processing, imaging, recording, verifying), expanding applications in imaging, archiving, Internet/intranet, CD production, and network backup and storage. (PEN)

Describes the advantages of optical data disk-based storage systems including cost, performance, and space required. Conversion from tape-based to optical disk-based data management via a flexible, hardware-based optical archiving system is discussed. (Author/LRW)

Explores the new storage technology of optical data disks and introduces a data structure, the inverted signature tree, for storing data on optical data disks for efficient text searching. The inverted signature tree approach is compared to the use of text signatures and the B+ tree. (22 references) (Author/CLB)

Describes compression methods for components of full-text systems such as text databases on CD-ROM. Topics discussed include storage media; structures for full-text retrieval, including indexes, inverted files, and bitmaps; compression tools; memory requirements during retrieval; and ranking and information retrieval. (Contains 53 references.)…

Presents the results of a comparative evaluation of four CD-ROM retrieval software packages using the Revised Richards-Brown CD-ROM Software Evaluation Model. CD Answer, SPIRS, KAware2, and ROMware are evaluated, and results indicate that SPIRS and CD Answer are the favored packages. (LRW)

Explores the 1988 "Books in Print Plus" (BIP Plus) CD-ROM database to determine broad characteristics of material currently in print in U.S. book trade in terms of publication year; price; language; and audience, grade level, and illustration. Accuracy and potential of BIP Plus as a tool for generating data and testing hypotheses…

Discusses the Scottish Newspapers Microfilming Unit's interest in conversion of microfilm to digital technology. Concerns include cost, potential market, reliability of digital technology as a preservation medium, and the necessity to have both microfilm and digital formats for preservation. Solicits feedback and information from colleagues on the…

Reports results of a comparison of the Academic Index on CD-ROM and four indexes on the OPAC (online public access catalog) at Brooklyn College (New York): General Science Index, Humanities Index, Readers' Guide to Periodical Literature, and Social Science Index. Coverage of the "New York Times" was found to be important. (LRW)

Provides an introduction to the technical aspects of digital audiotape and compares it to other computer storage devices such as optical data disks and magnetic tape cartridges in terms of capacity, transfer rate, and cost. The current development of digital audiotape standards is also discussed. (five references) (CLB)
