- 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
- 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
- For users, the catalogue is a tool to assist in satisfying information demands. Bibliographic databases raise the question of how to describe a document to facilitate retrieval. Information technology development have led to the creation of hypercatalogues, affording links to related material and other services. This necessitates improved descriptive cataloguing and also improved search interfaces to simplify user manipulation, along the lines of the Web. Given the massive output of electronic documents, the librarian's role is to select, prioritise and organise. The information society and its consequent economic consequences for the social organisation of knowledge raise the prospect of marginalisation of libraries. Catalogues enable access to knowledge as a public good, but this access must be democratic

- Abstract
- Works are key entities in the universe of recorded knowledge. Works are those deliberate creations (known variously as opera, oeuvres, Werke, etc.) that constitute individual sets of created conceptions that stand as the formal records of knowledge. In the information retrieval domain, the work as opposed to the document, has only recently received focused attention. In this paper, the definition of the work as an entity for information retrieval is examined. A taxonomic definition (that is, a definition built around a taxonomy) is presented. An epistemological perspective aids in understanding the components of the taxonomic definition. Works, thus defined as entities for information retrieval, are seen to constitute sets of varying instantiations of abstract creations. These variant instantiations must be explicitly identified in future systems for documentary information retrieval. An expanded perception of works, such as that presented in this paper, helps us understand the variety of ways in which mechanisms for their control and retrieval might better be shaped in future.

- Abstract
- Users' preferences for folders versus tags was studied in 2 working environments where both options were available to them. In the Gmail study, we informed 75 participants about both folder-labeling and tag-labeling, observed their storage behavior after 1 month, and asked them to estimate the proportions of different retrieval options in their behavior. In the Windows 7 study, we informed 23 participants about tags and asked them to tag all their files for 2 weeks, followed by a period of 5 weeks of free choice between the 2 methods. Their storage and retrieval habits were tested prior to the learning session and, after 7 weeks, using special classification recording software and a retrieval-habits questionnaire. A controlled retrieval task and an in-depth interview were conducted. Results of both studies show a strong preference for folders over tags for both storage and retrieval. In the minority of cases where tags were used for storage, participants typically used a single tag per information item. Moreover, when multiple classification was used for storage, it was only marginally used for retrieval. The controlled retrieval task showed lower success rates and slower retrieval speeds for tag use. Possible reasons for participants' preferences are discussed.

- Abstract
- This study examines problems caused by initial articles in library catalogs. The problematic records observed are those whose titles begin with a word erroneously considered to be an article at the retrieval stage. Many retrieval algorithms edit queries by removing initial words corresponding to articles found in an exclusion list even whether the initial word is an article or not. Consequently, a certain number of documents remain more difficult to find. The study also examines user behavior during known-item retrieval using the title index in library catalogs, concentrating on the problems caused by the presence of an initial article or of a word homograph to an article. Measures of success and effectiveness are taken to determine if retrieval is affected in such cases.

- Abstract
- Information seeking is a fundamental human activity. In the modern world, it is frequently conducted through interactions with search systems. The retrieval and comprehension of information returned by these systems is a key part of decision making and action in a broad range of settings. Advances in data availability coupled with new interaction paradigms, and mobile and cloud computing capabilities, have created a broad range of new opportunities for information access and use. In this comprehensive book for professionals, researchers, and students involved in search system design and evaluation, search expert Ryen White discusses how search systems can capitalize on new capabilities and how next-generation systems must support higher order search activities such as task completion, learning, and decision making. He outlines the implications of these changes for the evolution of search evaluation, as well as challenges that extend beyond search systems in areas such as privacy and societal benefit.

- 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
- Popular commercial on-line services such as Google, e-Bay, Amazon, and Netflix have evolved quickly over the last decade to help people find what they want, developing information retrieval strategies such as usefully ranked results, spelling correction, and recommender systems. Online library catalogs (OPACs), in contrast, have changed little and are notoriously difficult for patrons to use (University of California Libraries, 2005). Over the past year (June 2005 to the present), the Melvyl Recommender Project (California Digital Library, 2005) has been exploring methods and feasibility of closing the gap between features that library patrons want and have come to expect from information retrieval systems and what libraries are currently equipped to deliver. The project team conducted exploratory work in five topic areas: relevance ranking, auto-correction, use of a text-based discovery system, user interface strategies, and recommending. This article focuses specifically on the recommending portion of the project and potential extensions to that work.

- 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
- With the ever-increasing developments in information technology and networks, end users of the online environment now have integrated access to a variety of bibliographic databases, mainly library catalogues and A&I services, from a single terminal. While such a facility influences users' expectations and preferences in the searching, retrieval and presentation of bibliographic information, it raises an important question as to whether different bibliographic practices can use a similar or compatible set of principles for creating bibliographic records and files. This paper is an attempt to identify areas of possible reconciliation and also address some of the implications of such an issue.

- Abstract
- A discussion of the importance of clear cataloguing policies and routines as the basis of quality control, in relation to the methods used in the College of Mexico Library. The fundamental principle is to prevent errors occuring rather than to correct them subsequently. Indices of quality and effiency in relation to errors which do and do not affect retrieval, established through monthly review of samples of the work of each cataloguer, are used to monitor activities and ensure high standards. This process, essentially collaborative, promotes an overall culture of quality

- Abstract
- Describes the results of research to determine the extent of spelling errors in the State University of New York at Albany's online catalogue, whether these errors seriously affect users' access to library materials and what effect spelling errors will have on the group database planned for the State University of New York (SUNY). Using standard database tests, the catalogues of the four SUNY University Centers (Albany, Binghamton, Buffalo and Stony Brook) were studied. In addition, two comparison catalogues were studied: the New York State Library's Excelsior and California University's Melvyl. Results show that misspellings are unavoidable due to the way that most catalogues were built. These errors, however, are rarely an impediment to retrieval. Concludes with suggested ways to find and correct misspellings without expensive large scale efforts

- 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
- Examines the future for catalogues and cataloguers. Traces developments over the last decade: automation, networks, search and retrieve protocols and pwerful new PCs, which have forced and enabled massive cataloguing changes. Librarians have been good at adapting to new situations, but they have not accepted the standards developed for manual systems are not always applicable to today's automated systems. Discusses how new standards and systems can be developed to be of more relevance. Cataloguers need to be aware of the increasing digitization of material, and its impact in research and libraries, and be prepared to play their part in developing new information retrieval systems
