Abstract: Digital materials are reshaping library collections and, by extension, traditional library practice for collecting, organizing, and preserving information. This paper uses OCLC's WorldCat bibliographic database as a data source for examining questions relating to digital materials in library collections, including criteria for identifying digital materials algorithmically in MARC21 records; the quantity, types, characteristics, and holdings patterns of digital materials cataloged in WorldCat; and trends in WorldCat cataloging activity for digital materials over time. Issues pertaining to cataloging practice for digital materials and perspectives on digital holdings at the work level also are discussed. Analysis of the aggregate collection represented by the combined digital holdings in WorldCat affords a high-level perspective on historical patterns, suggests future trends, and supplies useful intelligence with which to inform decision making in a variety of areas.

Abstract: Recent trends, driven to a large extent by the rapid proliferation of digital resources, are forcing changes in bibliographic control to make it easier to use, understand, and apply subject data. Subject headings are no exception. The enormous volume and rapid growth of digital libraries and repositories and the emergence of numerous metadata schemes have spurred a reexamination of the way subject data are to be provided for such resources efficiently and effectively. To address this need, OCLC in cooperation with the Library of Congress, has taken a new approach, called FAST (Faceted Application of Subject Terminology). FAST headings are based on the existing vocabulary in Library of Congress Subject Headings (LCSH), but are applied with a simpler syntax than required by Library of Congress application policies. Adapting the LCSH vocabulary in a simplified faceted syntax retains the rich vocabulary of LCSH while making it easier to understand, control, apply, and use.

Abstract

Die Deutsche Bibliothek, the Library of Congress, and OCLC Online Computer Library Center are jointly developing a virtual international authority file (VIAF) for personal names which links authority records from the world's national bibliographic agencies and will be made freely available on the Web. The goals of the project are to prove the viability of automatically linking authority records from different national authority files and to demonstrate its benefits. The authority and bibliographic files from the Library of Congress and Die Deutsche Bibliothek were used to create the initial VIAF which contains over six million names with over a half million links. A key aspect of the project was the development of automated name matching algorithms which use information from both authority records and the corresponding bibliographic records. The practicality of algorithmically linking the personal names between national authority files was demonstrated; seventy percent of the authority records for personal names common to both files were automatically linked with an error rate of less than one percent. The long-term goal of the VIAF project is to combine the authoritative names from many national libraries and other significant sources into a shared global authority service.

Abstract: This article describes FAST, the Faceted Application of Subject Terminology, a project at OCLC to make Library of Congress Subject Headings easier to use in Dublin Core metadata by breaking out facets of space, time, and form. Work on FAST can be watched at its web site, http://www.miskatonic.org/library/, which has recent presentations and reports. It is interesting to see facets and Dublin Core combined, though both LCSH and FAST subject headings are beyond what most people making a small faceted classification would want or need.

Abstract

Form subdivisions have always been an important part of the Library of Congress Subject Headings. However, when the MARC format was developed, no separate subfield code to identify form subdivisions was defined. Form and topical subdivisions were both included within a general subdivision category. In 1995, the USMARC Advisory Group approved a proposal defining subfield v for form subdivisions, and in 1999 the Library of Congress (LC) began identifying form subdivisions with the new code. However, there are millions of older bibliographic records lacking the explicit form subdivision coding. Identifying form subdivisions retrospectively is not a simple task. An algorithmic method was developed to identify form subdivisions coded as general subdivisions. The algorithm was used to identify 2,563 unique form subdivisions or combinations of form subdivisions in OCLC's WorldCat. The algorithm proved to be highly accurate with an error rate estimated to be less than 0.1%. The observed usage of the form subdivisions was highly skewed with the 100 most used form subdivisions or combinations of subdivisions accounting for 90% of the assignments.

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

Two measures are examined that characterize the dispersion of a classification system when mapped to a second classification. One, a distance measure, captures the physical spread of a class when represented in the secon system; the second, from rank-frequency-analysis, characterizes the scatter of tokens over a set of types. The measures are tested by applying them to the library science portions of the LCC and the DDC using a database drawn from MARC records. Class mappings are presented that exemplify four extreme points of the two measures considered together: mappings where both measures score high, mappings where both score low, and mappings where one measure is high and the other is low. The conclusion is that the measures characterize two different properties of dispersion

Abstract

The goal of OCLC's FRBR projects is to examine issues associated with the conversion of a set of bibliographic records to conform to FRBR requirements (a process referred to as "FRBRization"). The goals of this FRBR project were to: - examine issues associated with creating an entity-relationship model for (i.e., "FRBRizing") a non-trivial work - better understand the relationship between the bibliographic records and the bibliographic objects they represent - determine if the information available in the bibliographic record is sufficient to reliably identify the FRBR entities - to develop a data set that could be used to evaluate FRBRization algorithms. Using an exemplary work as a case study, lead scientist Ed O'Neill sought to: - better understand the relationship between bibliographic records and the bibliographic objects they represent - determine if the information available in the bibliographic records is sufficient to reliably identify FRBR entities.

Abstract

The Library of Congress Subject Headings schema (LCSH) is by far the most commonly used and widely accepted subject vocabulary for general application. It is the de facto universal controlled vocabulary and has been a model for developing subject heading systems by many countries. However, LCSH's complex syntax and rules for constructing headings restrict its application by requiring highly skilled personnel and limit the effectiveness of automated authority control. Recent trends, driven to a large extent by the rapid growth of the Web, are forcing changes in bibliographic control systems to make them easier to use, understand, and apply, and subject headings are no exception. The purpose of adapting the LCSH with a simplified syntax to create FAST is to retain the very rich vocabulary of LCSH while making the schema easier to understand, control, apply, and use. The schema maintains upward compatibility with LCSH, and any valid set of LC subject headings can be converted to FAST headings.
