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

Libraries, private and public, offer valuable resources to library patrons. As of today, the only way to locate information archived exclusively in libraries is through their catalogs. Library patrons, however, often find it difficult to formulate a proper query, which requires using specific keywords assigned to different fields of desired library catalog records, to obtain relevant results. These improperly formulated queries often yield irrelevant results or no results at all. This negative experience in dealing with existing library systems turns library patrons away from directly querying library catalogs; instead, they rely on Web search engines to perform their searches first, and upon obtaining the initial information (e.g., titles, subject headings, or authors) on the desired library materials, they query library catalogs. This searching strategy is an evidence of failure of today's library systems. In solving this problem, we propose an enhanced library system, which allows partial, similarity matching of (a) tags defined by ordinary users at a folksonomy site that describe the content of books and (b) unrestricted keywords specified by an ordinary library patron in a query to search for relevant library catalog records. The proposed library system allows patrons posting a query Q using commonly used words and ranks the retrieved results according to their degrees of resemblance with Q while maintaining the query processing time comparable with that achieved by current library search engines.

Abstract

The starting-point of the paper is the debate recently developed in LIS literature about OPAC enhancement and the necessity to design OPACs based on search engines features. Supposed improving tools as relevance ranking and relevance feedback devices are examinated. Possible OPAC development lines, based on theoretical examination of relevance and pertinence concepts, according to Sarácevic view, and following semantics perspectives, are presented. Finally, enhancement of OPACs starting from their inner characteristics is proposed, and a plan to improve semantic search functions while maintaining existing indexing methodologies, that is document conceptual analysis, is outlined.

Abstract

Intended to contribute to the current dialogue about how the emerging information environment is impacting cataloging issues, this survey paper covers a broad range of topics, such as how search engines compare with integrated library systems, and includes some thoughts on how cataloging processes may evolve to continue to remain relevant. The author suggests that there is a need for significant changes in integrated library system interfaces and infrastructures as well as some changes in cataloging practice. The value of descriptive vs. non-descriptive elements in the catalog record and some pros and cons of the MARC format are covered.

Abstract

Purpose - Library online public access catalogues (OPACs) are considered to be unattractive in comparison with popular internet sites. In 2000, the authors presented some suggestions on how library catalogues should change. Have librarians actually made their OPACs more user-friendly by adopting techniques and technologies already present in other information resources? This paper aims to address these issues. Design/methodology/approach - The characteristics of four OPACs, one online bookstore and two internet search engines are analyzed. The paper reviews some of the changes and directions suggested by researchers and adds some of authors own. All this is in the hope that library catalogues will survive "Google attack." Findings - Changes are identified in the information services studied over a seven-year period. Least development is found in library catalogues. Suggestions are made for library catalogues of the future. Research limitations/implications - A library catalogue, a web search engine and an internet bookstore cannot be compared directly because of differences in scope. But features from each could be fruitfully used in others. Practical implications - OPACs must be both attractive and useful. They should be at least as easy to use as their competitors. With the results of research as well as the knowledge librarians have many years, the profession should be able to develop better OPACs than we have today and regain lost ground in the "competition" for those with information needs. Originality/value - A comparison of OPAC features in 2000 and 2007, even if subjective, can provide a panoramic view of the development of the field.

Abstract

Three factors are likely to force dramatic changes in the libraries of the future. They are the increase in electronic publishing, the digitising of conventional library materials, and the Internet which is creating a second information revolution. New concepts are needed for cataloguing functions in the Internet environment. Cataloguing, now a pre-coordinate function should shift to a post-coordinate activity. Authority control should become an activity of the searching stage rather than the cataloguing stage. Uniform titles will be needed as one of the linking mechanisms. The value of ISBD needs to be justified. Issues connected with the Internet and search engines are explored. A scenario for the Catalogue 2000 is given that envisions the cataloguers' aims being the inclusion of library catalogue material that is relevant but not necessarily in the library.

Abstract

Cataloging procedures have evolved in many academic research libraries over the past 10 years. Some predicted trends--outsourcing, original cataloging by paraprofessionals, more digital material--have been borne out. Others, such as a decline in the amount of material to catalog or in the number of professional catalogers, have not. Changes have been mostly procedural and have not affected the catalog itself. Recently, however, the emergence of powerful Internet search engines has allowed researchers to bypass the catalog. This has led some to question the wisdom of continuing it and others to vigorously defended current practice. In 2005-2007 this debate became especially heated, but a consensus appears to be emerging that although the character of the professional cataloger's job will continue to evolve over the next 5 to 10 years there will not be a revolution. The cataloger's basic skills will still be needed and the fundamental nature of cataloging will remain much as we know it.

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.

Abstract

Google[trademark] has become a nearly omnipresent tool of the Internet, with its potential only now beginning to be realised. How can librarians effectively integrate this powerful search engine to provide service to their patrons? "Libraries and Google[trademark]" presents leading authorities discussing the many possibilities of using Google products as effective, user-friendly tools in libraries. Google Scholar and Print are extensively explored with an eye towards offering an expanded view of what is and may be possible for the future, with practical insights on how to make the most of the product's capabilities.

Co-published simultaneously as Internet reference services quarterly, vol. 10(1005), nos. 3/4 Rez. in: ZfBB 54(2007) H.2, S.98-99 (D. Lewandowski): "Google und Bibliotheken? Meist hat man leider den Eindruck, dass hier eher ein oder gedacht wird. Dies sehen auch die Herausgeber des vorliegenden Bandes und nehmen deshalb neben Beiträgen zur Diskussion um die Rolle der Bibliotheken im Zeitalter von Google auch solche auf, die Tipps zur Verwendung unterschiedlicher Google-Dienste geben. Die allgemeine Diskussion um Google und die Bibliotheken dreht sich vor allem um die Rolle, die Bibliotheken (mit ihren Informationsportalen) noch spielen können, wenn ihre Nutzer sowieso bei Google suchen, auch wenn die Bibliotheksangebote (zumindest von den Bibliothekaren) als überlegen empfunden werden. Auch wenn die Nutzer geschult werden, greifen sie doch meist lieber zur einfachen Recherchemöglichkeit bei Google oder anderen Suchmaschinen - vielleicht lässt sich die Situation am besten mit dem Satz eines im Buch zitierten Bibliothekars ausdrücken: »Everyone starts with Google except librarians.« (5.95) Sollen die Bibliotheken nun Google die einfache Recherche ganz überlassen und sich auf die komplexeren Suchfragen konzentrieren? Oder verlieren sie dadurch eine Nutzerschaft, die sich mittlerweile gar nicht mehr vorstellen kann, dass man mit anderen Werkzeugen als Suchmaschinen bessere Ergebnisse erzielen kann? Diese sicherlich für die Zukunft der Bibliotheken maßgebliche Frage wird in mehreren Beiträgen diskutiert, wobei auffällt, dass die jeweiligen Autoren keine klare Antwort bieten können, wie Bibliotheken ihre Quellen so präsentieren können, dass die Nutzer mit der Recherche so zufrieden sind, dass sie freiwillig in den Bibliotheksangeboten anstatt in Google recherchieren. Den Schwerpunkt des Buchs machen aber nicht diese eher theoretischen Aufsätze aus, sondern solche, die sich mit konkreten Google-Diensten beschäftigen. Aufgrund ihrer Nähe zu den Bibliotheksangeboten bzw. den Aufgaben der Bibliotheken sind dies vor allem Google Print und Google Scholar, aber auch die Google Search Appliance. Bei letzterer handelt es sich um eine integrierte Hard- und Softwarelösung, die die Indexierung von Inhalten aus unterschiedlichen Datenquellen ermöglicht. Der Aufsatz von Mary Taylor beschreibt die Vor- und Nachteile des Systems anhand der praktischen Anwendung in der University of Nevada.
Ebenfalls direkt aus der Praxis erhält der Leser Informationen zum Google-PrintProgramm. Robert Milne beschreibt die Zusammenarbeit von Google und der Universität Oxford. In diesem Aufsatz wird - was dem Autor natürlich nicht anzulasten ist - ein Problem des vorliegenden Werks deutlich: Viele Informationen sind doch von sehr beschränkter Haltbarkeit. Der Redaktionsschluss war im Frühsommer 2005, sodass sich in vielen Bereichen bereits neue Entwicklungen ergeben haben. Dies ist beim Print-Programm der Fall, vor allem wird es aber bei dem Hauptthema des Bandes, nämlich Google Scholar, deutlich. Dieser Dienst wurde im November 2004 gestartet und stieß auf unterschiedlichste Reaktionen, die (anhand von Beispielen amerikanischer Bibliotheken) im Beitrag von Maurice C. York beschrieben werden. Einige Bibliotheken nahmen den Dienst begeistert auf und verlinkten diesen mit Lob versehen auf ihren Websites. Andere reagierten gegenteilig und warnten vor dessen schlechter Qualität. Auch weil vorauszusehen war, dass Google Scholar bei den Nutzern gut ankommen würde, darf das folgende Statement von einer Bibliothekswebsite geradezu als ignorant gelten: Google Scholar »is wonderful for those who do not have access to the library's databases« (S.119). Wie nun die Scholar-Nutzer auf die Bibliotheksangebote gelenkt werden können, beschreibt der ironisch »Running with the Devil« betitelte Aufsatz von Rebecca Donlan und Rachel Cooke. Die Autorinnen beschreiben den Einsatz von Link-Resolvern und gehen auf die in Google Scholar bestehenden Probleme durch unklare Bezeichnungen in den Trefferlisten ein. Einige Beispiele zeigen, dass Google Scholar auch in Kombination mit der Verlinkung auf die Bibliotheksbestände keine befriedigende Recherchesituation herstellt, sondern vielmehr weitere Anstrengungen nötig sind, um »das Beste beider Welten« zusammenzuführen. Zwei weitere Aufsätze beschäftigen sich mit der Frage, wie gut Google Scholar eigentlich ist. Einmal geht es darum, wie gut Scholar den »ACRL Information Literacy Standards« genügt. Der zweite Beitrag vergleicht Google Scholar anhand von fünf Suchaufgaben einerseits mit einem lokalen Bibliothekskatalog, andererseits mit EBSCOs Academic Search Premier und jeweils einer fachspezifischen Datenbank. Die Ergebnisse zeigen keine durchgehende Überlegenheit einer Suchlösung, vielmehr wird deutlich, dass es auf die Auswahl des richtigen Suchwerkzeugs für die bestehende Suchanfrage ankommt bzw. dass erst eine Kombination dieser Werkzeuge zu optimalen Ergebnissen führt. Man könnte also auch hier wieder sagen: Google und Bibliotheken, nicht Google oder Bibliotheken.

Abstract

Suchmaschinen befinden sich einerseits in einem beständigen Wandel. Andererseits gibt es immer wieder Entwicklungen, die die Suche "auf eine neue Ebene" heben. Eine solche Entwicklung, die wir zurzeit erleben, wird unter dem Label "Next Generation Search Systems" geführt. Der Begriff fasst die Veränderungen durch eine Vielfalt von Geräten und Eingabemöglichkeiten, die Verfügbarkeit von Verhaltensdaten en masse und den Wandel von Dokumenten zu Antworten zusammen.

Abstract

Despite the existence of a logical structural model for bibliographic records which integrates any record type, library catalogues persist in offering catalogue records at the level of 'items'. Such records however, do not clearly indicate which works they contain. Hence the search possibilities of the end user are unduly limited. The Functional Requirements for Bibliographic Records (FRBR) present through a conceptual model, independent of any cataloguing code or implementation, a globalized view of the bibliographic universe. This model, a synthesis of the existing cataloguing rules, consists of clearly structured entities and well defined types of relationships among them. From a theoretical viewpoint, the model is likely to be a good knowledge organiser with great potential in identifying the author and the work represented by an item or publication and is able to link different works of the author with different editions, translations or adaptations of those works aiming at better answering the user needs. This paper is presenting an interpretation of the FRBR model opposing it to a traditional bibliographic record of a complex library material.

Abstract

Continues the results of the Internet survey of 38 different OPAC systems, this looking at forms of name and cross-references. Tests were conducted to examine results of searching for a personal name, Leonardo da Vinci, and a corporate entered subordinately, under parts of the name which were not the leading element. Many libraries provide no cross-references, and in many cases the presence absence of punctuation in the search string has a significant effect. The effect variation when combined in an Author/Title search is also considered. The also considers the special filing of names beginning Mc, which is almost confined to some British systems, and the interfiling of subject with author entries personal names. A number of recommendations conclude the article.

Abstract

Three studies were made of the use of COM catalogues at the University of Toronto and the Mississauga Library System: unobtrusive observations, structured interviews, and a timed-search experiment in reel, fiche and card catalogues. The reel catalogue was found to be the overwhelming favourite, almost as popular in the public library as in the academic library, where 82% of the users reported it to be their preferred form of catalogue. However, for nearly all test questions and searcher types in the timed-search experiment, successful searches required less time in the card catalogue than in either form of the COM catalogues.

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.

Abstract

Genre/Form headings are an important means by which librarians provide users with contextual or descriptive information. To facilitate the discovery of resources with important provenance characteristics, the Marion E. Wade Center added terms from a controlled vocabulary to bibliographic records representing items in the C. S. Lewis personal library collection. The selected terms focus on features that have historically been of interest to visitors. The addition of these headings in the bibliographic records allows users to use these keywords to conduct a search or narrow their results, resulting in more flexibility to locate and select the resources that best meet their needs.

Abstract

This paper presents the first large-scale investigation of the users and uses of WorldCat.org, the world's largest bibliographic database and global union catalog. Using a mixed-methods approach involving focus group interviews with 120 participants, an online survey with 2,918 responses, and an analysis of transaction logs of approximately 15 million sessions from WorldCat.org, the study provides a new understanding of the context for global union catalog use. We find that WorldCat.org is accessed by a diverse population, with the three primary user groups being librarians, students, and academics. Use of the system is found to fall within three broad types of work-task (professional, academic, and leisure), and we also present an emergent taxonomy of search tasks that encompass known-item, unknown-item, and institutional information searches. Our results support the notion that union catalogs are primarily used for known-item searches, although the volume of traffic to WorldCat.org means that unknown-item searches nonetheless represent an estimated 250,000 sessions per month. Search engine referrals account for almost half of all traffic, but although WorldCat.org effectively connects users referred from institutional library catalogs to other libraries holding a sought item, users arriving from a search engine are less likely to connect to a library.

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.
