- Abstract
- Extensive literatures exist on information searching theory and techniques, as well as on the Bradford Distribution. This distribution, also known as "Bradford's Law of Scattering," tells us that information on a subject is dispersed in a characteristic and robust pattern that appears consistently across many different environments. This pattern may be expected to have important implications for information searching theory and techniques. Yet these two research literatures are rarely considered in relation to each other. It is the purpose of this article to distinguish three Bradford regions and speculate on the optimum searching techniques for each region. In the process, browsing, directed searching in databases, and the pursuit of various forms of links will all be considered. Implications of growth in size of a literature for optimal information organization and searching will also be addressed.

- Abstract
- An Internet survey of 38 different OPAC systems, at eighty different libraries, was undertaken to investigate the effect on retrieval of the presence of the hyphen or the ampersand in titles. Title and Keyword searches were performed. In Title search, 22 of the systems treat the hyphen as equivalent to a space, while in Keyword the number is 16. The other systems treat it in various different ways (even including the equivalent of NOT), which means that results of searching multiple catalogs are very inconsistent. The ampersand may be ignored, treated as a special character, or treated as "and," again with very inconsistent results. Various recommendations are made with a view to improving consistency of performance.

- Abstract
- Pays tribute to the recent advances in the ability to access computerized catalogues from the desktop via the Internet but emphasizes that there are problems still to be overcome before the ideal of universal access to catalogue records for UK libraries is achieved. Advances in computerized cataloguing over the past 40 years have been an obstacle to retrospective cataloguing in a coherent and standardized manner which even the adoption of common standards for information retrieval and the Z39.50 protocol have failed to prevent. Many libraries with modern methods for cataloguing new materials still have earlier sequences of records on microfiche or other hard copy format. Other specialized collections are such that they have never been catalogued to professional standards or in a convenient format. Illustrates the point with reference to practical searching of catalogues in Aberystwyth, Wales, and to 2 studies of the logistical and financial issues of a programme of retrospective cataloguing as reported in BLRIC report 53. Discusses the proposed UK coordinating body and coordinated natioanl prgramme, to select which catalogues should be converted, set priorities for work, ensure maintenance of requisite standards, and arrange collaboration between neighbouring or related institutions

- Abstract
- This study explored the functionality of the University of Chicago's faceted catalog, Lens, in respect to monographic series. A user study was designed to evaluate the efficiency of Lens in searching for monographic series and also to determine whether controlled series access in the catalog record improves the search results. The results of the study indicate that while Lens could be considered an adequate tool for searching series that are known to be published under the same title, some changes would make it a better search engine for a series that changes series statements from one volume to another.

- 1. Introduction In this paper we address two questions: 1. What is the position of subject indexing in the thinking of the library world after the publication of the Functional Requirements for Bibliographic Records (1998)? 2. Is this position in accordance with the requirements of the users searching for documents about a given subject? Research Shows that searching an a topic (i.e. subject access) is an important, even predominant type of end-user searching of library catalogues and even more so of other bibliographic databases. Between one third and two thirds of all OPAC searches are probably subject searches (Large & Beheshti, 199%). Taking into account different ways in which searching an a topic is implemented in library catalogues (subject headings, classification, keywords only) the percentage may be even higher. For example title word searching may be a substitute for subject searching if no better tools are available. In the light of this it is not surprising that the Functional Requirements for Bibliographic Records (FRBR) (1998) pays attention to subject searching, as well as the Functional Requirements and Numbering of Authority Records (FRANAR) (2003). Also the Statement of International Cataloguing Principles: Final draft of 19 December 2003, which is the result of the first First IFLA Meeting of Experts an an International Cataloguing Code mentiong subject access as a function of cataloguing (Statement, 2003). In this paper we discuss the ways these three documents deal with subjects.

- Abstract
- In pt.1, argued that modern classification theory and philosophy of science can help us understand problems of searching. In pt.2, discusses the problems in a more technical sense. considers thesauri and studies of of concept formation: choice of subject headings; definitions, and associations between subject headings; and the librarian as intermediary between the users and the library's texts. Tests the hypothesis that a catalogue record can be improved by adding information which makes the record more precise. If a record clearly indicates that a book is a typical or non-typical book on a subject, no improvement is necessary. discusses how and what new information to add and psychological barriers to this

- Abstract
- Library information searching lacks a descriptive theory which explains how a user decides to borrow one book and not another. Such theory should act as a reference framework against which cataloguing rules and the classification system can be measured, and should be based on 2 complementary perspectives, described in detail: modern classification theory, which explains what cataloguing and classification involve, and philosophy of science, which explains what happens when the user meets the catalogue record. Catalogue information must answer which work is described, and why this work on the subject is chosen. A descriptive theory is especially necessary for knowing what new information to add to the catalogue. Discusses this in a subsequent article

- Abstract
- As of spring semester 2010, Georgia Southern University began using a VuFind implementation as the default access to the library catalogue on the library Web page while maintaining a secondary link to the traditional Voyager "classic" catalogue. VuFind is an open-source product that has been adopted and adapted by all the state universities and colleges in the state of Georgia. For approximately ten years, Georgia libraries have used Voyager as their catalogue, and it remains available to users as the "classic" search option. This report examines the local VuFind implementation compared to the more traditional Voyager implementation, emphasizing the differences in the searching capabilities of each.

- Abstract
- Subject searching is difficult with traditional text-based online public access library catalogues (OPACs), and the next-generation discovery layers are keyword searching and result filtering tools that offer little support for subject browsing. Next-generation OPACs ignore the rich network of relations offered by controlled subject vocabulary, which can facilitate subject browsing. A new generation of OPACs could leverage existing information-organization investments and offer online searchers a novel browsing and searching environment. This is a case study of the design and development of a virtual reality subject browsing and information retrieval tool. The functional prototype shows that the Library of Congress subject headings (LCSH) can be shaped into a useful and usable tree structure serving as a visual metaphor that contains a real world collection from the domain of science and engineering. Formative tests show that users can effectively browse the LCSH tree and carve it up based on their keyword search queries. This study uses a complex information-organization structure as a defining characteristic of an OPAC that goes beyond the standard keyword search model, toward the cutting edge of online search tools.

- Abstract
- Reports results of an analysis of 205 randomly selected records from the OCLC OLUC, to test the assumption that online catalogues have greatly improved subject searching capabilities, over card catalogues, by making other fields in the records searchable as subject access points (SAPs). Results showed considerable overlap (duplication) among the SAPs provided by the title, subject heading and classification number fields. On average, little more than 4 unique, unduplicated access points were found per record. Where title and classification number fields do add some access points not provided by subject headings, the increase is less than many librarians might be expected. Suggests that OPACs might outperform catalogues more in precision than in recall by allowing greater discrimination in searching; terms from different fields may be combined; titles offer greater specifity; searches can be limited by date, language or other criteria
