Abstract

National exercises for the evaluation of research activity by universities are becoming regular practice in ever more countries. These exercises have mainly been conducted through the application of peer-review methods. Bibliometrics has not been able to offer a valid large-scale alternative because of almost overwhelming difficulties in identifying the true author of each publication. We will address this problem by presenting a heuristic approach to author name disambiguation in bibliometric datasets for large-scale research assessments. The application proposed concerns the Italian university system, comprising 80 universities and a research staff of over 60,000 scientists. The key advantage of the proposed approach is the ease of implementation. The algorithms are of practical application and have considerably better scalability and expandability properties than state-of-the-art unsupervised approaches. Moreover, the performance in terms of precision and recall, which can be further improved, seems thoroughly adequate for the typical needs of large-scale bibliometric research assessments.

Abstract

The FRBR model is by many considered to be an important contribution to the next generation of bibliographic catalogues, but a major challenge for the library community is how to use this model on already existing MARC-based bibliographic catalogues. This problem requires a solution for the interpretation and conversion of MARC records, and a tool for this kind of conversion is developed as a part of the Norwegian BIBSYS FRBR project. The tool is based on a systematic approach to the interpretation and conversion process and is designed to be adaptable to the rules applied in different catalogues.

Abstract

Libraries and museums developed rules for the description of their collections prior to formalizing the underlying conceptualization reflected in such rules. That formalizing process took place in the 1990s and resulted in two independent conceptual models: FRBR for bibliographic information (published in 1998), and CIDOC CRM for museum information (developed from 1996 on, and issued as ISO standard 21127 in 2006). An international working group was formed in 2003 with the purpose of harmonizing these two models. The resulting model, FRBROO, was published in 2009. It is an extension to CIDOC CRM, using the formalism in which the former is written. It adds to FRBR the dynamic aspects of CIDOC CRM, and a number of refinements (e.g. in the definitions of Work and Manifestation). Some modifications were made in CIDOC CRM as well. FRBROO was developed with Semantic Web technologies in mind, and lends itself well to the Linked Data environment; but will it be used in that context?

Abstract

The article presents the work of Elaine Svenonius The Intellectual Foundation of Information Organization, translated in Italian and published by Le Lettere of Florence, within the series Pinakes, with the title Il fondamento intellettuale dell'organizzazione dell'informazione. The Intellectual Foundation of Information Organization defines the theoretical aspects of library science, its philosophical basics and principles, the purposes that must be kept in mind, abstracting from the technology used in a library. The book deals with information organization and bibliographic universe, in particular using the bibliographic entities defined in FRBR, at first. Then, it analyzes all the specific languages by which works and subjects are treated. This work, already acknowledged as a classic, organizes, synthesizes and make easily understood the whole complex of knowledge, practices and procedures developed in the last 150 years.

Abstract

Teaching cataloguing requires the instructor to make strategic decisions about how to approach the variety and complexity of the field and to provide an adequate theoretical foundation while preparing students for their entry into the world of practice. Accompanying these challenges are the tactical demands of providing this instruction in a distance education environment. Rather than focusing on ways to support learners in catalogue record production, instructors may use a problem solving and decision making approach to instruction. In this paper, a way to conceptualize a decision making approach that builds on a foundation provided by theories of information navigation is described. This approach, which is called "wayfinding", teaches by having students learn to find their way in the sets of rules that are commonly used. The method focuses on instruction about the structural features of rule sets, providing basic definitions of what each of the "places" in the rule sets contain (e.g., "formatting personal names" in Chapter 22 of AACR2R) and about ways to navigate those structures, enabling students to learn not only about common rules but also about less well known cataloguing practices ("dragons"). It provides both pragmatic and pedagogical benefits and helps develop links between cataloguing practices and their theoretical foundations.

Abstract

The report from the IFLA (International Federation of Library Associations and Institutions) Study Group on the Functional Requirements for Bibliographic Records (FRBR) recommended a new approach to cataloging based on an entity-relationship model. This study examined a single work, The Expedition of Humphry Clinker, to determine benefits and drawbacks associated with creating such an entity-relationship model. Humphry Clinker was selected for several reasons - it has been previously studied, it is widely held, and it is a work of mid-level complexity. In addition to analyzing the bibliographic records, many books were examined to ensure the accuracy of the resulting FRBR model. While it was possible to identify works and manifestations, identifying expressions was problematic. Reliable identification of expressions frequently necessitated the examination of the books themselves. Enhanced manifestation records where the roles of editors, illustrators, translators, and other contributors are explicitly identified may be a viable alternative to expressions. For Humphry Clinker, the enhanced record approach avoids the problem of identifying expressions while providing similar functionality. With the enhanced manifestation record, the three remaining entity-relationship structures - works, manifestations, and items - the FRBR model provides a powerful means to improve bibliographic organization and navigation.

Abstract

The current library bibliographic infrastructure was constructed in the early days of computers - before the Web, XML, and a variety of other technological advances that now offer new opportunities. General requirements of a modern metadata infrastructure for libraries are identified, including such qualities as versatility, extensibility, granularity, and openness. A new kind of metadata infrastructure is then proposed that exhibits at least some of those qualities. Some key challenges that must be overcome to implement a change of this magnitude are identified.

Abstract

In this article, we present a method to automatically build large labeled datasets for the author ambiguity problem in the academic world by leveraging the authoritative academic resources, ORCID and DOI. Using the method, we built LAGOS-AND, two large, gold-standard sub-datasets for author name disambiguation (AND), of which LAGOS-AND-BLOCK is created for clustering-based AND research and LAGOS-AND-PAIRWISE is created for classification-based AND research. Our LAGOS-AND datasets are substantially different from the existing ones. The initial versions of the datasets (v1.0, released in February 2021) include 7.5 M citations authored by 798 K unique authors (LAGOS-AND-BLOCK) and close to 1 M instances (LAGOS-AND-PAIRWISE). And both datasets show close similarities to the whole Microsoft Academic Graph (MAG) across validations of six facets. In building the datasets, we reveal the variation degrees of last names in three literature databases, PubMed, MAG, and Semantic Scholar, by comparing author names hosted to the authors' official last names shown on the ORCID pages. Furthermore, we evaluate several baseline disambiguation methods as well as the MAG's author IDs system on our datasets, and the evaluation helps identify several interesting findings. We hope the datasets and findings will bring new insights for future studies. The code and datasets are publicly available.

Abstract

In this manual, expert cataloguer Ed Jones shows you how to catalogue serials using the new cataloguing standard, RDA: Resource Description and Access. Serials and continuing resources present a variety of unique challenges in bibliographic management, from special issues and unnumbered supplements to recording the changes that a long-running periodical can experience over time. Easing cataloguers through the RDA: Resource Description and Access transition by showing the continuity with past practice, serials cataloguing expert Jones frames the practice within the structure of the FRBR and FRAD conceptual models on which RDA is based. With serials' special considerations in mind, this essential guide explains the familiarities and differences between AACR2 and RDA and demonstrates how serials cataloguers' work fits in the cooperative context of OCLC, CONSER and NACO. Jones looks in detail at the process of cataloguing serials and ongoing integrating resources using RDA, from attributes and relationships between works to identifying related entities. Finally, looking at the possibilities offered by Linked Data, he presents examples of how RDA records can ultimately engage with the Semantic Web.

Abstract

A survey of 261 libraries was undertaken to determine the level of use of and duties performed by student assistants in monographic cataloging operations. Ninety-five of 142 responding libraries (64.1 percent) indicate that they use student assistants for some type of monographic cataloging tasks. These tasks are downloading of bibliographic and authority records, monographic cataloging, classification, subject heading authority control, holdings, database maintenance, and editing of 246 or 505 MARC tags. Some respondents expressed reluctance to use student assistants for higher-level cataloging tasks.

Abstract

False imprint information and other deceptive publication details present problems for catalogers. In this article, I describe different types of misleading information, including fictitions names of publishers, incorrect places of publication, and false dates; mention possible reasons for deception, including fear of prosecution, and emphasize the need for catalogers to be suspicious when handling certain types of material. Erotic printed materials and bootleg sound recordings are discussed in detail, and examples of misleading information in each medium and explanations of how cataloging rules address or fail to address specific circumstances are included. Catalogers need to be aware of both the potential problems associated with certain types of materials and the types of reference sources to consult when dealing with those materials.

Abstract

The Library of Congress is participating in a number of initiatives to explore issues surrounding description and cataloging of digital materials. Addtionally, programs have been written by LC staff which enable electronic enhancements in cataloging activities, such as the receipt of online information from publishers in the Electronic CIP Program. This paper is both an overview of the status of cataloging-related digital projects at LC and a description of software which facilitates productivity through the provision of software which facilitates productivity through the provision of advanced search capabilities and the elimination of repetitive keying.
