Presents three text compression methods of increasing power and evaluates each based on the trade-off between compression gain and processing time. The advantages of using hash coding for speed and optimal arithmetic coding to successor information for compression gain are discussed. (26 references) (Author/CLB)

Examines two models to study the consequences for coding efficiency of sample fluctuations, a specific type of error in the statistics on which data compression codes are based. The possibility that random fluctuation can be exploited for data compression is discussed. (six references) (KRN)

Evaluated whether different scores on Rey Auditory-Verbal Learning Test are measures of different memory domains. Factor analyses on data from 146 subjects produced 1, 2, or 3 factors depending on combination of scores in analysis and criteria used to determine number of factors. Basic factors were acquisition and retention. Subdividing retention…

Discusses provisions of the Digital Millennium Copyright Act (DCMA) that relate to special librarians and offer a limitation on liability for online service providers. Highlights include eligibility requirements; storing material and referring users to material at other locations through hypertext links or search engines; system caching; and scope…

Discusses data exchange over the Internet and describes the architecture and implementation of an XML document repository that promotes a navigation paradigm for XML documents based on content and context. Topics include information retrieval and semistructured documents; and file systems as information storage infrastructure, particularly XMLFS.…

Examines the role of microfilm in storing information to eliminate digital obsolescence. Discusses the benefits of digital-to-analog microfilm systems; changes in conventional microfilm technology; and the advantages of true hybrid imaging systems that allow retrieval of images from document microfilm, digitally created microfilm or paper scanners…

What's the worst thing that can happen to a computer? Worse than a hard disk crash, virus infection, spare assault, denial-of-service attack, hacker take-over, fire, flood or some other human, mechanical or natural disaster is a faulty backup when it is really needed. If the computer blows up, as long as the data is backed up securely, it can be…

This document discusses the importance of data-quality and presents three simple steps that can help lay the framework for an over all data-quality strategy. The first step is to ask some rather simple questions, such as: (1) How much data does the organization have, how fast is it creating new data, and how many redundant copies are there?; and…

The New Media Consortium's Horizon Project is an ongoing research project that seeks to identify and describe emerging technologies likely to have a large impact in education and other industries around the world over a five-year time period. The chief products of the project are the "Horizon Reports", an annual series of publications…

Computer literacy has evolved from writing simple BASIC programs to using desktop productivity applications. The shift from mainframe to personal computer brought about the need to rethink computer literacy courses to introduce basic skills and familiarity using desktop productivity applications. While these skills remain important, the recent…

This publication discusses optical storage, a term encompassing technologies that use laser-produced light to record and store information in digital form. The booklet also discusses how optical storage systems relate to records management, in particular to the management of local government records in New York State. It describes components of…

This report examines the potential impact of optical media--videodiscs, compact audio discs, and optical disks, tapes, and cards--in library related applications. A detailed consideration of the technology includes discussion of the underlying principles, the various forms in which the technology is marketed, production methods and costs, and the…

This report presents the results of the initial phase of the File Organization Project, a study which focuses upon the on-line maintenance and search of the library's catalog holdings record. The focus of the project is to develop a facility for research and experimentation with the many issues of on-line file organizations and search. The first…

To investigate and resolve some of the problems associated with developing a permanent state-wide occupational information service system for planning and programing vocational education, a small scale data bank was developed for six selected countries in Alabama. Inputs were collected from 38 high schools offering vocational education, two…

Seven experts in system planning offer their views on how optical disk systems will affect library participation in online networks, and discuss opportunities presented by these new products. (CLB)
