Explores the effects of library use on both capacitance and laser-optical videodisc systems and outlines proper cleaning, servicing, and storage techniques. The article is excerpted from "Conservation in the Library," a book edited by Susan Swartzberg. (Author/JJD)

Describes the results of a survey of the records management needs of various organizations. Focuses on the use of and need for hard- and software media for storage retrieval, microimage processing, job titles and responsibilities relating to records management, electronic funds transfer, and reprographics. (CT)

Describes the requirements, data elements, functions and systems design for an online search log which maintains records of search services provided. (CWM)

Examines design functions of present file organizations in the context of available data storage devices and identifies current developmental trends. (Author/RAA)

Offers suggestions for avoiding common errors in online microcomputer use. Areas discussed include learning the basics; hardware protection; backup options; hard disk organization; software selection; file security; and the use of dedicated communications lines. (CLB)

Describes a study that was conducted to investigate and describe the way in which people organize documents in their offices. Results from the investigation of eight faculty members are discussed and analyzed, the process used to make classification decisions is described, and implications for conventional systems of classification are suggested.…

Reviews the literature relating to the development and application of modern imaging technology between 1987 and 1993. Highlights include image representation, including image data, compression, and image formats; and image access, including indexing and modeling, user interface design, and distributed access. (143 references) (LRW)

Describes a detailed algorithm for fast text compression. Related to the PPM (prediction by partial matching) method, it simplifies the modeling phase by eliminating the escape mechanism and speeds up coding by using a combination of quasi-arithmetic coding and Rice coding. Details of the use of quasi-arithmetic code tables are given, and their…

Describes the design of optimal tree-structured vector quantizers that minimize the expected distortion subject to cost functions related to storage cost, encoding rate, or quantization time. Since the optimal design problem is intractable in most cases, the performance of a general design heuristic based on successive partitioning is analyzed.…

Discusses information retrieval and the use of binary trees as a fast access method for search strategies such as hashing. Proposes new methods based on compact binary trees that provide faster access and more compact storage, explains the theoretical basis, and confirms the validity of the methods through empirical observations. (LRW)

Describes the Accomplishment-Based Curriculum Development model, which provide a cohesive framework for the processes of human performance technology and instructional design. Topics include front-end analysis; behavior characteristics; information storage and retrieval; materials development; and the contributions of Joe Harless to the field.…

The literature on information literacy often assumes that there is an inherent link between the need for information literacy and what is commonly referred to as the information explosion. This assumed link is reflected in programs of information literacy instruction offered by academic libraries. This article argues that the basic concepts of…
