The direct-chaining technique of hash coding is generalized in a manner that is useful for storing records on the basis of non-unique search keys. Two hash functions are used, a process implying a tree structure. Two models, one involving unique and the other non-unique keys, are presented. (7 references) (Author/KE)

The computer system described was developed as a departmental aid in locating documents for use as teaching material or for research purposes in the area of information science.

The Information Flow System is a large-scale information retrieval system developed for processing of Du Pont information files. As currently implemented, the system stores and retrieves information on company technical reports. Extensions of the system for handling chemical structure information and on-line processing are also discussed. (3…

Delineated in this bibliography are the characteristics of a number of retrospective bibliographies in one major division of scholarship--the social sciences--in an attempt to identify and sort out the various purposes toward which works in this format appear to be directed.

Distance education created new challenges regarding the delivery of large size isochronous continuous streaming media (SM) objects. In this paper, we consider the design of a framework for customized SM presentations, where each presentation consists of a number of SM objects that should be retrieved and displayed to the user in a coherent…

This report is a survey of five on-line retrieval systems that, with one exception, have been used to demonstrate on-line access to the recently developed Committee on Scientific and Technical Information (COSATI) inventory of government sponsored work now in progress in the area of information sciences and technology. The report was prepared to…

The existing volume and increasing growth rate of documented information has resulted in numerous efforts to construct operational Document Storage and Retrieval Systems, as a practical solution to the demand for information storage and retrieval. Accompanying the surge to build more and better and bigger Document Retrieval Systems (DRSs), was the…

The materials of a library, exemplified by books, have traditionally been viewed as presenting two aspects involving two distinct problems: their description and control as unique items, and their treatment as sources of information on various subjects. But this view has tended to overlook a third fundamental aspect: that of the "works" which are…

This report presents an analysis of the problem of descriptive cataloging as a whole: the aspects of the problem, the questions they raise, the issues involved, the course adopted in the new "Anglo-American Cataloging Rules," and the principles that would serve best the objectives of the catalog.

The preservation of digital data for the long term presents a variety of challenges from technical to social and organizational. The technical challenge is to ensure that the information, generated today, can survive long term changes in storage media, devices, and data formats. This paper presents a novel approach to the problem. It distinguishes…

Describes an online library catalog in which bibliographic references have been compiled by simply transcribing the descriptive data found on the title page and elsewhere on the documents, and discusses the wider implications of the use of natural language descriptions without modifications. Eleven references are listed. (FM)

Examines various types of link list structures built on top of the traditional random access files for application to a database query technique involving multiple keys, and shows how the technique can improve performance of traditional random access files for the Grants Information System.
