    Abstract
    Authority files have played an important role in improving the quality of indexing and subject cataloging. Although authorities can significantly improve search by increasing the number of access points, they are rarely an integral part of the information retrieval process, particularly end-users searches. A retrieval prototype, searchFAST, was developed to test the feasibility of using an authority file as an index to bibliographic records. searchFAST uses FAST (Faceted Application of Subject Terminology) as an index to OCLC's WorldCat.org bibliographic database. The searchFAST methodology complements, rather than replaces, existing WorldCat.org access. The bibliographic file is searched indirectly; first the authority file is searched to identify appropriate subject headings, then the headings are used to retrieve the matching bibliographic records. The prototype demonstrates the effectiveness and practicality of using an authority file as an index. Searching the authority file leverages authority control work by increasing the number of access points while supporting a simple interface designed for end-users.

    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
    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.

    Abstract
    Normalization rules are essential for interoperability between bibliographic systems. In the process of working with Name Authority Cooperative Program (NACO) authority files to match records with Functional Requirements for Bibliographic Records (FRBR) and developing the Faceted Application of Subject Terminology (FAST) subject heading schema, the authors found inconsistencies in independently created NACO normalization implementations. Investigating these, the authors found ambiguities in the NACO standard that need resolution, and came to conclusions on how the procedure could be simplified with little impact on matching headings. To encourage others to test their software for compliance with the current rules, the authors have established a Web site that has test files and interactive services showing their current implementation.

Describes a methodology to collect a representative sample of publicly accessible Web documents and suggests analyses which will benefit libraries and the Internet community in trying to characterise these information sources

    Abstract
    Word aboutness is defined as the relationship between words and subjects associated with them. An aboutness coefficient is developed to estimate the strength of the aboutness relationship. Words that are randomly distributed across subjects are assumed to lack aboutness and the degree to which their usage deviates from a random pattern indicates the strength of the aboutness. To estimate aboutness, title words and their associated subjects are extracted from the titles of non-fiction English language books in the OCLC WorldCat database. The usage patterns of the title words are analyzed and used to compute aboutness coefficients for each of the common title words. Words with low aboutness coefficients (An and In) are commonly found in stop word lists, whereas words with high aboutness coefficients (Carbonate, Autism) are unambiguous and have a strong subject association. The aboutness coefficient potentially can enhance indexing, advance authority control, and improve retrieval.

    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
    A system based authority control system was essential to support OCLC's large database and the number and diversity of its users. The authority control system had to be able to (1) identify nonidentical heading entries in bibliographic records of the same name, geographic place, or subject, and (2) maintain a link from the erroneous form of the heading to the valid form (i.e. cross reference). Over 3.6 million headings have been corrected as part of these efforts

    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
