Addressing the problem of protecting confidential information and data stored in computer databases from access by unauthorized parties, this paper details coding schemes which present such astronomical work factors to potential code breakers that security breaches are hopeless in any practical sense. Two procedures which can be used to encode for…

Described is the file organization and design of an on-line catalog suitable for automation of one million books. A method of virtual hash addressing allows rapid search of the indexes to the catalog file. Storage of textual material in a compressed form allows considerable reduction in storage costs.

Discusses use of communications software packages as a means of linking a microcomputer with other computers, endowing it with characteristics of a terminal, and still preserving many personal computer features. Required features, additional features, and books and guidebooks are noted. (EJS)

Describes an online microcomputer-based system called Reference Librarian Enhancement System (REFLES) which stores factual information. Examples of data in the system and uses of the service are presented, as well as considerations for the future. Twelve (12) references are included. (Author/BK)

Describes XMARC, a set of computer programs which provides students with a simplified means of writing programs for the automatic indexing of an experimental collection of MARC records. (Author/FM)

WISE is an on-line, interactive information retrieval system designed to operate on key-word-oriented data bases. The WISE user searches a data base by entering and combining key-words that are appropriate to the data base and the subject matter. The user also enters certain command statements to enhance the results of the search and to control…

In-house library databases or "private files" (online catalog, library-created indexes, citations to journal literature) are discussed, focusing on computer software directories, periodicals, general directories, and online directories as sources for information on computer software. (EJS)

This article shows how MAGIC, a computer language formulated by a major supplier of business-oriented numeric data which works in conjunction with the APL programing language, provides an effective management tool for analysis and presentation of business-oriented data (private or public) by nonprogrammers. Illustrative material is presented. (EJS)

Provides a generalized overview of the problems that software buyers are likely to encounter and could overcome. Experiences of Online, Inc., in purchasing programs, using software documentation or manuals, and problems with software, provide examples. (EJS)

Describes the use of IBM's Storage and Information Retrieval System (STAIRS) in the development of an online catalog for the Business and Technical Library of the Cummins Engine Company. The functions, advantages, and disadvantages of the system are outlined. A reference list and three sample searches are attached. (JL)

Describes the replication agreements between WLN and replicating institutions such as the National Library of Australia and the University of Illinois whereby use of WLN software is permitted on the basis of reciprocity of bibliographic information by the contracting parties. (RAA)

This paper is concerned with providing automatically generated online explanations to the user of a user interface or "tool" about what the interface can and cannot do, and what parameters or options are available or required with a given command. The COUSIN interface system, developed at Carnegie-Mellon, supplies a cooperative…

Describes an automated system for cataloging nonprint media received by the Copyright Office for registration. Problems in disseminating this unique data base through national networks are considered. The system features automatic inversion of personal names and the use of one entry as a model for the next. (Author/VT)

Issues having a possible impact on online search services in libraries are discussed including full text databases, front-end processors which translate user's input into the command language of an appropriate system, downloading to create personal files from commercial databases, and pricing. (EJS)
