Construction of the locant path, a table of interatom connections, and the molformula from the WLN for complex ring systems (including polycyclic, spiro, perifused, bridged, and pseudo-bridged rings) is described. The procedure has been programmed for a digital computer and has been found useful in manual decoding also. (Author)

An experiment in manipulating machine-readable library records for use in subject searching indicated that such programs would be useful to extend service outside a single library location. (Author/PF)

This paper suggests one way that trends in the literature might be captured by historians through the use of computerized information retrieval services and particular statistical techniques for analyzing trends. For illustrative purposes, the topic "desegregation" was investigated in Lockheed's DIALOG (1982) information retrieval system…

A project which developed a retrieval system to evaluate the advantages and disadvantages of an interactive computer and video display system over traditional methods for using a slide library is described in this publication. The art school slide library of the University of Iowa stores transparencies which are arranged alphabetically within…

The Broad System of Ordering (BSO), a subject-indication coding and ordering scheme developed to meet the requirements of the UNISIST program for an international switching mechanism between information systems using diverse indexing/retrieval languages is described. The scope and purpose of the BSO, its development and testing, a schematic…

This manual presents the operations of British Columbia's computerized facilities inventory for post-secondary institutions. A brief summary describes the kinds of code tables used, the forms used to feed data into the computer, the types of printout reports available, and the responsibilities of institutions using the system.

This report describes the composition and operation of the library of the Gray Freshwater Biological Institute at the University of Minnesota, a non-traditional information service which provides information to the institute by combining the use of three bibliographic databases with current awareness services, OCLC, MINITEX, and author reprint…

The users of online retrieval systems can and should provide feedback to the system operators or vendors to influence them to make changes and further improvements, or to reinforce operator's decisions to make changes in the systems. All members of the database chain--database producers, processors, search service brokers, searchers, and end users…
