“…Various analyses of the MARC 21 formats have dealt extensively with the relationship between FRBR and MARC 21, 66 and others have written specifically about methodology for FRBRizing a MARC-based catalog. 67 In addition, various tools and Web services are available that can potentially facilitate this process. 68 Even with this extensive body of work to draw upon, however, the success of our implementation of FRBR-based functionality will depend upon both the quality and completeness of the system's metadata.…”

Metadata to Support Next-Generation Library Resource Discovery: Lessons from the eXtensible Catalog, Phase 1

The eXtensible Catalog (XC) L ibrary metadata, whether in the form of MARC 21 catalog records or in a variety of newer metadata schemas, has served its purpose for library users by facilitating their discovery of library resources within online library catalogs (OPACS), digital libraries, and institutional repositories. However, libraries now face the challenge of making this wealth of legacy catalog data function adequately within next-generation Web discovery environments. Approaching this challenge will require: n an understanding of the metadata itself and a commitment to deriving as much value from it as possible; n a vision for the capabilities of future technology; n an understanding of the needs of current (and, where possible, future) library users; and n a commitment to ensuring that lessons learned in this area inform the development of both future library systems and future metadata standards.The University of Rochester's eXtensible Catalog (XC) Project will bring these various perspectives together to design and develop a set of open-source, collaboratively built next-generation discovery tools for libraries. The XC Project Team seeks to make the best possible use of legacy library metadata, while also informing the future development of discovery metadata for libraries. During Phase 1 of the XC Project (2006)(2007), the XC Project Team created a plan for developing XC and defined the goals and initial functional requirements for the system. This paper outlines the major metadatarelated issues that the XC Project Team and XC Partner Institutions will need to address to build the XC system during Phase 2. It also describes how the XC Team and XC Partners will address these issues, and concludes by presenting a number of issues for the broader library community to consider.While this paper focuses on the work of a single library project, the goals and functional requirements developed for the XC Project reveal many generalizable needs for metadata to support a next-generation discovery system.1 The metadata-related goals of the XC Project-to facilitate the use of MARC metadata outside an Integrated Library System (ILS), to combine MARC metadata with metadata from other sources in a single discovery environment, and to facilitate new functionality (e.g., faceted browsing, user tagging)-are very similar to the goals of other library projects and commercial vendor discovery software. The issues described in this paper thus transcend their connection to the XC Project and can be considered general needs for library discovery metadata in the near future.In addition to informing the library community about the XC Project and encouraging comment on that work, the author hopes that identifying and describing metadata issues that are important for XC-and that are likely to be important for other projects as well-will encourage the library community to set these issues as high priorities for attention and action within the next few years.

“…Aalberg, as well as Hickey and O'Neill, provides illustrations of current work in creating such algorithms. 32 The results of this study highlight some issues that may arise in the transition from AACR2 to RDA. Looking at the organization of the rules in RDA and AACR2 in relation to the results of this study, two main differences are apparent.…”

The Distributions of MARC Fields in Bibliographic Records

Library catalog systems worldwide are based on collections of MARC records. New kinds of Functional Requirements for Bibliographic Records (FRBR)-based catalog retrieval systems, displays, and cataloging rules will build on ever-growing MARC record collections. Characterizing the kinds of information held in MARC records is thus an important step in developing new systems and rules. This study examined the incidence and prevalence rates of MARC fields in two different sets of library catalog records: a random selection of bibliographic records from the Library of Congress online catalog and a selection of records for two specific works, Lord of the Flies and Plato's Republic. Analysis showed that most fields were used in only a small percentage of records, while a small number of fields were used in almost all records. Power law functions proved to be a good model for the observed distribution of MARC fields. The results of this study have implications for the design of new cataloging procedures as well as for the design of catalog interfaces that are based on the FRBR entity-relationship model. M ARC records are at the center of library cataloging processes. The MARC format, developed in the 1960s, is unlikely to be replaced in the foreseeable future, both because of its proven utility and because of the legacy volumes of existing MARC records held by libraries around the world. While the MARC format may not be going anywhere soon, the ways that MARC records are created and used are in a state of transition. Functional Requirements for Bibliographic Records (FRBR) outlined a conceptual model to describe the bibliographic universe. 1 Implementing the FRBR model in MARC-based cataloging practices and information retrieval systems has proven challenging. Numerous technical, structural, and institutional challenges must be overcome for libraries to shift to FRBR-based cataloging schemes and online catalog displays. Any new methods for cataloging and displaying library resources will be built from the existing MARC record databases. Thus understanding the state of the current data stored in MARC records is essential to the process of moving forward with new display systems and cataloging schemes. This study serves the effort to better understand these challenges by more fully characterizing the kinds of information that can be found in MARC records. Specifically, this study aims to identify and characterize the patterns in the ways catalogers use MARC fields in bibliographic records by quantifying which fields are most commonly present in library catalog records. The author used two different samples of bibliographic records in this study. First, a random selection of The Distributions of MARC Fields in Bibliographic Records 41 bibliographic records from the Library of Congress (LC) online catalog were collected and examined. Second, a case study approach was used to analyze smaller samples of records from two specific works: William Golding's Lord of the Flies and Plato's Republic. This study tests whether a power ...

“…by adding missing uniform title and relator codes, or coding information in note fields or responsibility statements using explicit fields. Afterwards, the data has been transformed using a rule-based FRBRization process [5]. Collections used in the experiments presented in this paper include crime fiction novels and short stories and other works related in different ways, and a collection of publications of Don Quixote in various languages and editions.…”

Abstract. The model of bibliographic entities defined in the IFLA Functional Requirements for Bibliographic Records (FRBR) represents a major transition from the digital card catalog to databases containing a rich structure of entities and relationships with well-defined semantics. However, the question of how to best search and present this entity-centric bibliographic data remains a challenge. In this paper we present a system for entity-centric search and a user study on how the displays of the FRBR entities compare in their ability to support different user tasks.
