- 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
- 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
- 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
- Contends that library catalogues need to be seen as merely part of the information seeker's world and proposes the concept of a learning catalogue for library clients which will capture ways in which clients use data thus providing ideas for the further development of the system. Proposes a client centred system which is separated to maintain the bibliographic database from the mode of presentation of that data to the client. The designer of retrieval systems, by accepting that each client brings a unique view of the world's knowledge base to the information seeking activity, needs to acknowledge that this view of the world must be handled uniquely. By overlaying the idea of a learning component, it is possible to see how future queries might be handled more efficiently and the system can grow with client's developing needs

- 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
- 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
- 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
- The destabilizing influences of the Web, widespread ownership of personal computers, and rising computer literacy have created an era of discontinuous change in research libraries a time when the cumulated assets of the past do not guarantee future success. The library catalog is such an asset. Today, a large and growing number of students and scholars routinely bypass library catalogs in favor of other discovery tools, and the catalog represents a shrinking proportion of the universe of scholarly information. The catalog is in decline, its processes and structures are unsustainable, and change needs to be swift. At the same time, books and serials are not dead, and they are not yet digital. Notwithstanding widespread expansion of digitization projects, ubiquitous e-journals, and a market that seems poised to move to e-books, the role of catalog records in discovery and retrieval of the world's library collections seems likely to continue for at least a couple of decades and probably longer. This report, commissioned by the Library of Congress (LC), offers an analysis of the current situation, options for revitalizing research library catalogs, a feasibility assessment, a vision for change, and a blueprint for action. Library decision makers are the primary audience for this report, whose aim is to elicit support, dialogue, collaboration, and movement toward solutions. Readers from the business community, particularly those that directly serve libraries, may find the report helpful for defining research and development efforts. The same is true for readers from membership organizations such as OCLC Online Computer Library Center, the Research Libraries Group, the Association for Research Libraries, the Council on Library and Information Resources, the Coalition for Networked Information, and the Digital Library Federation. Library managers and practitioners from all functional groups are likely to take an interest in the interview findings and in specific actions laid out in the blueprint.

- Abstract
- Approaches to the measurement of catalog record quality are discussed. The systematic application of specific evaluation criteria may be more reliable than expert opinion, if not necessarily more accurate, and the construction of an error weightings table based on empirical investigation into catalog use is described. Although this process proved to be complex, and involved significant methodological problems, it was shown to be readily achievable. As catalog use may in many cases be insufficiently uniform across libraries to allow for generic evaluation criteria, it is proposed that cataloging managers construct their own set by studying the impact that record quality has on the particular use of their own catalogs. Thus more empirical research into catalog use is advocated, in order to supplement expert opinion and to build toward a practice of evidence-based cataloging.

- Abstract
- Catalogers have become interdependent in their pursuit to provide bibliographic control and access. This interdependency has brought with it the need for greater agreement in applying common cataloging policies and rules. The expanded application of AACR2 (Anglo-American Cataloguing Rules) is fostering greater uniformity in the provision of bibliographic description and access. The rules have been translated into numerous languages and used in European, Middle Eastern, and Latin American countries. Cataloging committees and individual libraries in Europe and South Africa have expressed strong interest in adopting, adapting, or aligning with AACR2. PCC (Program for Cooperative Cataloguing) is one of the most successful cooperative cataloging efforts and has a considerable international component, which encourages the use of AACR, LCSH (Library of Congress Subject Headings), and MARC. AACR2 is successful on an international level because it is based in internationally developed standards, including ISBDs and the Paris Principles. ISBDs (International Standard Bibliographic Description) and the Functional Requirements for Bibliographic Records are examples of the contributions that IFLA (International Federation of Library Associations and Institutions) has made to the internationalization of cataloging. IFLA sponsored the international conference that resulted in the Paris Principles as well as subsequent projects to craft international policy in relation to uniform headings for persons, corporate bodies, and titles.

- Abstract
- Purpose - To examine whether placing URLs into library OPACs has been an effective way of enhancing the role of the catalogue for the contemporary library user. Design/methodology/approach - A brief review of the literature combined with an analysis of publicly available statistics for library use in the USA and the UK. Findings - That certain ways of placing URLs into the OPAC are loosely associated with a successful library environment, i.e. with constant or increasing levels of stock circulation and OPAC use, while other forms of hyper-linking OPAC records are loosely associated with declining levels of library use. Research limitations/implications - The loose association between different OPAC management practices and apparent statistical trends of library use could be investigated in greater depth by further subsequent research, but along the lines and methodology suggested herein. Practical implications - Firm suggestions on how to place and manage URLs in the online catalogue are made. Originality/value - This paper takes certain catalogue enhancement practices which are identified with the US library environment and investigates them in a UK, and specifically Scottish context, to shed light on the original US ideas behind these practices.

- 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
- This paper proposes a conceptual model for cataloging which gives primacy to expression-level bibliographic entity, with the aim of approaching critical issues in cataloging, such as the so-called "format variations" and "content versus carrier" issues. The term "expression" is defined as "the intellectual or artistic realization of a work in the form of alpha-numeric, musical, or choreographic notation, etc." In this paper, the model by the IFLA Study Group on Functional Requirements for Bibliographic Records (FRBR) is first re-examined and at the same time the outline of a new model giving primacy to expression-level entity is illustrated by indicating differences from the FRBR model. Second, by applying the concept "user tasks," found in the FRBR model, to the new model outlined in this paper, a scenario on how entities are used by users is created. Third, some examples of bibliographic record equivalents in line with the new model are shown.

- 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
- Next-generation catalogues can be viewed as the latest manifestation of a tendency in library catalogue history to strive for centralization of access to collections-a single portal for the discovery of library resources. Due to an increasing volume of published materials and the explosion of online information resources during the Internet age, the library does not currently provide centralized access to its various information silos, nor does it provide a user-friendly search and retrieval experience for users whose expectations are shaped by Google and other major commercial Web sites. Searching across library resources is a complicated task, bearing high-attention "transaction costs" for the user, which discourage the use of library resources. Libraries need access systems that minimize complexity, easing discovery and delivery of resources for user populations. Here, the authors review past efforts of centralization of access, consider the potential of next-generation catalogues in the context of this historical tendency toward centralization of access, and describe what goals underlie that centralization.

- 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
- To improve resource discovery and retrieval, libraries have implemented new discovery services, such as next generation catalogues, federated search, and Web-scale discovery, in addition to their traditional integrated library systems. These new discovery services greatly improve the user experience by utilizing existing cataloguing records housed within the library system or in combination with metadata from other sources, both in and outside of libraries. However, to maximize the functionality of these discovery services, libraries must reexamine current cataloguing practices and the way libraries control the bibliographic description to better serve the user's needs. This report discusses how new discovery services use the cataloguing records and the challenges that libraries encounter in bibliographic control to work with new discovery services, including the quality of cataloguing records, granular levels of bibliographic description, and integration of user-generated metadata into the cataloguing records. Each of these aspects requires further discussion.

- Abstract
- Libraries are currently seeking to restructure their services and develop new cataloguing standards to position themselves on the web, which has become the main source of information and documents. The current upheaval within the profession is accompanied by the belief that libraries have a major role to play in identifying and supplying content due to their extensive high quality databases, which remain untapped despite efforts to increase catalog performance. They continue to rely on a strategy that has been proven successful since the mid-nineteenth century while seeking other models for their data. Today, they aim to exploit changes brought about by the web to improve content identification. The current intense debate on RDA implementation mirrors this desire for change. The debate is rooted in past efforts and yet tries to incite radical changes as it provides for interoperability from the creation of records through an object modeling in line with web standards and innovations. These innovations are presented through an historical perspective inspired by writings by librarians who are entrusted with helping in the development of bibliographic description standards.
