Describes the general methodology of time and motion studies and reports the results of a study which used this methodology to compare digitization of images in a microcomputer environment with storage of images on microforms. (CLB)

Focusing primarily on hard disks, this report describes the choices currently available; explains the inner workings of hard-disk technology; lists 70 leading hard-disk products with their costs and capabilities; describes a new type of high-capacity drive; and compares speed, cost, and reliability of a number of widely used hard-disk backup…

This hardware review describes such innovative features of the Texas Instrument Portable Professional Computer as integrated color screen and option slots permitting customization as well as the physical unit (inside and out), its mass storage flexibility, and sturdiness. A comparison with the IBM PC Portable is included. (MBR)

Categorizes software packages for microcomputer database creation by their typical features and strengths, and discusses appropriate applications of each category. A directory of vendors for each type of software--text retrieval, file managers, database management, information storage and retrieval, integrated bibliographic systems, and library…

Discusses major features of microcomputers (word length, memory, size, disk size and capacity, central processing unit speed, peripherals, software) and provides descriptions of 19 models. Comparative analysis on basis of cost, software support, machine capacity, storage capacity, and types of peripherals is presented. A 173-item bibliography is…

Lists and compares specifications, properties, and test results of eight microcomputer software programs for information storage and retrieval by endusers. This is one of a series of articles that have reported the results of a software evaluation project conducted by The Netherlands Association of Users of Online Information Systems (VOGIN). (22…

Discusses criteria for evaluating microcomputer database management systems (DBMS) used for storage and retrieval of bibliographic data. Two popular types of microcomputer DBMS--file management systems and relational database management systems--are evaluated with respect to these criteria. (Author/MBR)

Discusses trends in computer technology and their use for library catalogs, noting the concept of bandwidth (describes quantity of information transmitted per given unit of time); computer hardware differences (micros, minis, maxis); distributed processing systems and databases; optical disk storage; networks; transmission media; and terminals.…

This summary of the literature on document image processing from 1988-90 focuses on WORM (write once read many) technology and on rewritable (i.e., erasable) optical discs, and excludes CD-ROM. Highlights include vendors and products, standards, comparisons of storage media, software, legal issues, records management, indexing, and computer…

The fourth in a series of articles on the evaluation of microcomputer software for information storage and retrieval, conducted by the Netherlands Association of Users of Online Information Systems (VOGIN), presents test results for six indexing and full-text retrieval programs--Ask-It, KAware, Texplore, TextMaster, WordCruncher, and ZYindex. (13…

Uses the different search environments of information brokers and institutional searchers to illustrate the factors that should be considered when selecting microcomputers for search operations. The factors discussed include speed, storage capabilities, displays, modems, printing technologies, facsimile transmission, and portability. A directory…

Reports on tests evaluating nine microcomputer software packages designed for information storage and retrieval: BRS-Search, dtSearch, InfoBank, Micro-OPC, Q&A, STN-PFS, Strix, TINman, and ZYindex. Tables and narrative evaluations detail results related to security, hardware, user features, search capability, indexing, input, maintenance of files,…

Two LOGO dialects are compared for appropriateness for use with second, third, and fourth grade students on the basis of 18 months of experience with teaching LOGO programing language at this level in a four-machine laboratory setting. Benefits and drawbacks of the dialects are evaluated in the areas of editing. screen modes, debugging,…

Describes experiments in Arabic information retrieval using 29 queries against a base of 355 bibliographic records. Using roots and stems as index terms worked better than words, and the root performed as well as or better than the stem at low recall levels and definitely better at high recall levels. (Contains 30 references.) (KRN)
