Abstract

This article describes experiments in the use of machine learning techniques at the British Library to assign language codes to catalog records, in order to provide information about the language of content of the resources described. In the first phase of the project, language codes were assigned to 1.15 million records with 99.7% confidence. The automated language identification tools developed will be used to contribute to future enhancement of over 4 million legacy records.

Abstract

Integrating resources are distinct in that they change over time in such a way that their previous content is replaced with updated content. This study examines how integrating resources can be modeled using the entities and relationships of the IFLA Library Reference Model (LRM) and clarifies how they can be identified. While monographs have been extensively analyzed, integrating resources have received very little attention. Applying the model unmodified to integrating resources is neither practical nor theoretically sound. With the addition of two proposed relationships, the model can be extended to accommodate the diachronic relationship intrinsic between expressions and manifestations exhibited by integrating resources.

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

The circ stats say it all: graphic novels' popularity among library users keeps growing, with more being published (and acquired by libraries) each year. The unique challenges of developing and managing a graphics novels collection have led the Association of Library Collections and Technical Services (ALCTS) to craft this guide, presented under the expert supervision of editor Ballestro, who has worked with comics for more than 35 years. Examining the ever-changing ways that graphic novels are created, packaged, marketed, and released, this resource gathers a range of voices from the field to explore such topics as: a cultural history of comics and graphic novels from their World War II origins to today, providing a solid grounding for newbies and fresh insights for all; catching up on the Big Two's reboots: Marvel's 10 and DC's 4; five questions to ask when evaluating nonfiction graphic novels and 30 picks for a core collection; key publishers and cartoonists to consider when adding international titles; developing a collection that supports curriculum and faculty outreach to ensure wide usage, with catalogers' tips for organizing your collection and improving discovery; real-world examples of how libraries treat graphic novels, such as an in-depth profile of the development of Penn Library's Manga collection; how to integrate the emerging field of graphic medicine into the collection; and specialized resources like The Cartoonists of Color and Queer Cartoonists databases, the open access scholarly journal Comic Grid, and the No Flying, No Tights website. Packed with expert guidance and useful information, this guide will assist technical services staff, catalogers, and acquisition and collection management librarians.

Abstract

Library Technical Services have benefited from numerous stimuli. Although initially looked at with suspicion, transitions such as the move from catalog cards to the MARC formats have proven enormously helpful to libraries and their patrons. Linked data and Artificial Intelligence (AI) hold the same promise. Through the conversion of metadata surrogates (cataloging) to linked open data, libraries can represent their resources on the Semantic Web. But in order to provide some form of controlled access to unstructured data, libraries must reach beyond traditional cataloging to new tools such as AI to provide consistent access to a growing world of full-text resources.

Abstract

Descriptive cataloging is the process of representing resources by recording their identifying traits and selecting specific names and titles to serve as access points. It is a key component of the larger cataloging process alongside subject cataloging, authority work, and encoding. Descriptive cataloging practices have existed for centuries and, over time, have become standardized through the use of cataloging codes. These documents guide this process by prescribing a consistent set of elements, providing directions on how to record these elements, and offering instructions on how to select and format access points. The goal of descriptive cataloging is not to create perfect representations but to provide data to serve users. The international cataloging standard Resource Description and Access (RDA) is now bringing more institutions under the same set of descriptive practices than ever before. This, along with recent technological developments, promises increased sharing and reuse of descriptive cataloging data.

Abstract

The concept of authorship is central to how libraries organize their collections. But libraries do not only collect resources created by individuals, they also collect documents issued by organizations. Library catalogers use the concept of a "corporate body" to treat organizations as authors for the purpose of making their documents discoverable to users. This essay looks at the key features of establishing authorized access points (AAPs) and applying authority control for corporate bodies. It examines how practices with regard to corporate bodies have changed over time and considers the changes catalogers might expect to see in the future.

Abstract

This study uses the recently released Cataloguing Code of Ethics to evaluate a project which explored how to ethically, efficiently, and accurately add demographic terms for African-American authors to catalog records. By reviewing the project through the lens of these principles the authors were able to examine how their practice was ethical in some ways but could have been improved in others. This helped them identify areas of potential improvement in their current and future research and practice and explore ethical difficulties in cataloging resources with records that are used globally, especially in a linked data environment.

Abstract

This article discusses the practical application of faceted vocabularies to the cataloging of textbooks. Consistent application of faceted vocabularies, specifically Library of Congress Genre/Form Terms for Library and Archival Materials (LCGFT) and Library of Congress Demographic Group Terms (LCDGT), would enhance the discovery of these resources. Alternatives to special cases in Subject Heading Manual H 2187 are proposed. A case study demonstrating the application of LCDGT is provided. Figures illustrate the results of the proposed best practices. The article includes four tables that are designed to streamline term assignments. Consistent cataloging of genre and audience prepares legacy records for future automated enhancement.

Abstract

Library catalogs remain challenging for children to use, especially because children have difficulty with multi-step processes, have less semantic and technical knowledge, and often search differently from adults. Child-friendly catalogs should have clear, simple protocols and visual guides that are standardized yet include flexible options for differentiated manipulation. Materials should be described accurately and in ways that connect meaningfully to children. More fundamentally, cataloging children's materials needs to be done in light of children as potential users and limitations of the integrated library management system itself. Getting children's feedback in the process can optimize the results.

Abstract

This paper discusses the basics of creating name authority records for Arabic personal names in accordance with Resource Description and Access instructions and Program for Cooperative Cataloging guidelines. A background into the use of romanization for non-Latin scripts in bibliographic and authority records is provided to establish the context. Issues with romanization that are particular to Arabic are addressed. Separate sections on modern and classical names provide an overview of the major challenges, and strategies to enhance discovery are outlined. The paper concludes with an examination of the possible benefits of identity management and other changes in the authority control landscape for names in non-Latin script.

Abstract

Persistent identifiers (PID's) are essential for getting access and referring to library, archive and museum (LAM) collection objects in a sustainable and unambiguous way, both internally and externally. Heritage institutions need a universal policy for the use of PID's in order to have an efficient digital infrastructure at their disposal and to achieve optimal interoperability, leading to open data, open collections and efficient resource management. Here the discussion is limited to PID's that institutions can assign to objects they own or administer themselves. PID's for people, subjects etc. can be used by heritage institutions, but are generally managed by other parties. The first part of this article consists of a general theoretical description of persistent identifiers. First of all, I discuss the questions of what persistent identifiers are and what they are not, and what is needed to administer and use them. The most commonly used existing PID systems are briefly characterized. Then I discuss the types of objects PID's can be assigned to. This section concludes with an overview of the requirements that apply if PIDs should also be used for linked data. The second part examines current infrastructural practices, and existing PID systems and their advantages and shortcomings. Based on these practical issues and the pros and cons of existing PID systems a list of requirements for PID systems is presented which is used to address a number of practical considerations. This section concludes with a number of recommendations.
