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

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

This article presents an overview of some of the important recent developments in cataloging theory and practice and online catalog design. Changes in cataloging theory and practice include the incorporation of the Functional Requirements for Bibliographic Records principles into catalogs, the new Resource Description and Access cataloging manual, and the new CONSER Standard Record. Web 2.0 functionalities and advances in search technology and results displays are influencing online catalog design. The paper ends with hypothetical scenarios in which a catalog, enhanced by the developments described, fulfills the tasks of finding serials articles and titles.

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

This paper presents several reflections on the traditional card catalogues and RDF (Resource Description Framework), which is "the" standard for creating the Semantic Web. This work grew out of discussion between the authors after Working Group on Metadata Schemes meeting held at IFLA conference in Buenos Aires (2004). The paper provides an overview of RDF from the perspective of cataloguers, catalogues and library cards. The central theme is the discussion of resource description as a discipline that could be based on RDF. RDF is explained as a very simple grammar, using metadata and ontologies to semantic search and access. RDF Knitting the Semantic Web Cataloging & Classification Quarterly Volume 43, Numbers 3/4 has the ability to enhance 21st century libraries and metadata interoperability in digital libraries, while maintaining the expressive power that was available to librarians when catalogues were physical artefacts.

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

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.

Content

1. Introduction With the diversification of the material available in library collections such as: music, film, 3D objects, cartographic material and electronic resources like CD-ROMS and Web sites, the existing cataloguing principles and codes are no longer adequate to enable the user to find, identify, select and obtain a particular entity. The problem is not only that material fails to be appropriately represented in the catalogue records but also access to such material, or parts of it, is difficult if possible at all. Consequently, the need emerged to develop new rules and build up a new conceptual model able to cope with all the requirements demanded by the existing library material. The Functional Requirements for Bibliographic Records developed by an IFLA Study Group from 1992 through 1997 present a generalised view of the bibliographic universe and are intended to be independent of any cataloguing code or implementation (Tillett, 2002). Outstanding scholars like Antonio Panizzi, Charles A. Cutter and Seymour Lubetzky formulated the basic cataloguing principles of which some can be retrieved, as Denton (2003) argues as updated versions, between the basic lines of the FRBR model: - the relation work-author groups all the works of an author - all the editions, translations, adaptations of a work are clearly separated (as expressions and manifestations) - all the expressions and manifestations of a work are collocated with their related works in bibliographic families - any document (manifestation and item) can be found if the author, title or subject of that document is known - the author is authorised by the authority control - the title is an intrinsic part of the work + authority control entity

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

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

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

Over the past year, innumerable discussions on the relationship between traditional library OPACs and the newly burgeoning World WideWeb have occured in many libraries and in virtually every library related discussion list. Rumors and speculation abound, some insisting that SGML will replace USMARC "soon," others maintaining that OPACs that haven't migrated to the Web will go the way of the dinosaurs.

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

The conflict between librarians' ethics and their responsibilities in the process of progressive collection management, which applies the principles of cost accounting to libraries, to call attention to the "bad books" in their collections that are compromised by age, error, abridgement, expurgation, plagiarism, copyright violation, libel, or fraud, is discussed. According to Charles Cutter, notes in catalog records should call attention to the best books but ignore the bad ones. Libraries that can afford to keep their "bad books," however, which often have a valuable second life, must call attention to their intellectual contexts in notes in the catalog records. Michael Bellesiles's Arming America, the most famous case of academic fraud at the turn of the twenty-first century, is used as a test case. Given the bias of content enhancement that automatically pulls content from the Web into library catalogs, catalog notes for "bad books" may be the only way for librarians to uphold their ethical principles regarding collection management while fulfilling their professional responsibilities to their users in calling attention to their "bad books."

Abstract

Many libraries and other cultural institutions are incorporating Web 2.0 features and enhanced metadata into their catalogs (Trant 2006). These value-added elements include those typically found in commercial and social networking sites, such as book jacket images, reviews, and usergenerated tags. One such site that libraries are exploring as a model is LibraryThing (www.librarything.com) LibraryThing is a social networking site that allows users to "catalog" their own book collections. Members can add tags and reviews to records for books, as well as engage in online discussions. In addition to its service for individuals, LibraryThing offers a feebased service to libraries, where institutions can add LibraryThing tags, recommendations, and other features to their online catalog records. This poster will present data analyzing the quality and quantity of the metadata that a large academic library would expect to gain if utilizing such a service, focusing on the overlap between titles found in the library's catalog and in LibraryThing's database, and on a comparison between the controlled subject headings in the former and the user-generated tags in the latter. During February through April 2008, a random sample of 383 titles from the University of Minnesota Libraries catalog was searched in LibraryThing. Eighty works, or 21 percent of the sample, had corresponding records available in LibraryThing. Golder and Huberman (2006) outline the advantages and disadvantages of using controlled vocabulary for subject access to information resources versus the growing trend of tags supplied by users or by content creators. Using the 80 matched records from the sample, comparisons were made between the user-supplied tags in LibraryThing (social tags) and the subject headings in the library catalog records (controlled vocabulary system). In the library records, terms from all 6XX MARC fields were used. To make a more meaningful comparison, controlled subject terms were broken down into facets according to their headings and subheadings, and each unique facet counted separately. A total of 227 subject terms were applied to the 80 catalog records, an average of 2.84 per record. In LibraryThing, 698 tags were applied to the same 80 titles, an average of 8.73 per title. The poster will further explore the relationships between the terms applied in each source, and identify where overlaps and complementary levels of access occur.

Abstract

A bibliographic record is a conceptual whole that includes all bibliographic information about a resource together in one place. With the Semantic Web, individual data statements are linked across the web. This position article argues that the traditional conceptualization of bibliographic records affects the affordances and limitations of that data. A historical analysis of the development of bibliographic records contrasted with the Semantic Web model reveals how the "record" model shaped library cataloging and the implications on library catalogs today. Reification of the record model for bibliographic data hampers possibilities for innovation in cataloging, inspiring a reconceptualization of bibliographic description.

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

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

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.
