Compares the ELHILL 2 and STAIRS programs with respect to on-line searching of the MEDLARS citation file by means of a chart showing the capabilities of the two programs. (Author/PF)

Describes features of two computer programs, Z-Term--The Professional, or Z-Pro, and Transcend, to demonstrate that telecommunications software can greatly expand the capabilities of a microcomputer. (MBR)

The two-part ZCPR2 System (system itself and related utilities) runs in place of CP/M 2.2 CCP. These public domain programs provide functions similar to those provided by CCP, but offer many enhancements. ZCPR2 programs, features, documentation, and uses are discussed. Problems in using ZCPR2 are also discussed. (JN)

The report describes the general structure of the Intrex Retrieval Systems and each of the component subroutines. The report is not an introduction to Intrex. In addition to a general description, the report covers the following topics: (1) system architecture, (2) software details, (3) command control logic, (4) list manipulation logic, (5)…

Regional online users groups and a state library association offer professional librarians and librarian computer hobbiests opportunities to experiment with microcomputers. (RAA)

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…

What is the desirability and usefulness of different thesaurus displays used either singly or in groups? Is an alphabetical listing of terms with cross references more useful to an indexer than a complete hierarchical display? Is the permuted or the rotated term index more useful to the indexer or retriever? Is an alphabetical display along with a…

SPIRES (Stanford Public Information REtrieval System) is a computer information storage and retrieval system being developed at Stanford University with funding from the National Science Foundation. SPIRES has two major goals: to provide a user-oriented, interactive, on-line retrieval system for a variety of researchers at Stanford; and to support…

A FORTRAN program for clustering variables using the alpha coefficient of reliability is described. For batch operation, a rule for stopping the agglomerative precedure is available. The conversational version of the program allows the user to intervene in the process in order to test the final solution for sensitivity to changes. (Author/JKS)

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. (14 references) (Author/SJ)

A modular program is recommended for automation of the clippings file of "The Daily Texan" (student newspaper of the University of Texas at Austin). The proposed system will lead ultimately to on-line storage of the index, on-line storage of local, staff-written news stories from the previous twenty-four months, micrographic storage for backup and…

Intrex is an experimental bibliographic and full text storage and retrieval system which has advanced the concept of the on-line interactive search of a computer stored bibliographic data base and the on-line access to a microfiche document storage. The Intrex system includes a set of computer programs designed for information retrieval, a…

Description of "Decision-Analyst," microcomputer software tool designed to analyze complex decisions involving many alternatives, highlights step-by-step approach, documentation, microcomputer requirements, and purchasing information. Two microcomputer users' groups (Apple Computer, Microcomputer Users Group for Libraries in North…

A little understood aspect of implementing on-line software is the problem of effective monitoring. Northwestern University has developed techniques to monitor an on-line information retrieval system, by using that system both to monitor itself and to process the data collected. The Remote Information Query System is a batch and on-line…

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)
