- Abstract
- The Alexandria Digital Library (ADL) Project has developed a content standard for gazetteer objects and a hierarchical type scheme for geographic features. Both of these developments are based on ADL experience with an earlier gazetteer component for the Library, based on two gazetteers maintained by the U.S. federal government. We define the minimum components of a gazetteer entry as (1) a geographic name, (2) a geographic location represented by coordinates, and (3) a type designation. With these attributes, a gazetteer can function as a tool for indirect spatial location identification through names and types. The ADL Gazetteer Content Standard supports contribution and sharing of gazetteer entries with rich descriptions beyond the minimum requirements. This paper describes the content standard, the feature type thesaurus, and the implementation and research issues. A gazetteer is list of geographic names, together with their geographic locations and other descriptive information. A geographic name is a proper name for a geographic place and feature, such as Santa Barbara County, Mount Washington, St. Francis Hospital, and Southern California. There are many types of printed gazetteers. For example, the New York Times Atlas has a gazetteer section that can be used to look up a geographic name and find the page(s) and grid reference(s) where the corresponding feature is shown. Some gazetteers provide information about places and features; for example, a history of the locale, population data, physical data such as elevation, or the pronunciation of the name. Some lists of geographic names are available as hierarchical term sets (thesauri) designed for information retreival; these are used to describe bibliographic or museum materials. Examples include the authority files of the U.S. Library of Congress and the GeoRef Thesaurus produced by the American Geological Institute. The Getty Museum has recently made their Thesaurus of Geographic Names available online. This is a major project to develop a controlled vocabulary of current and historical names to describe (i.e., catalog) art and architecture literature. U.S. federal government mapping agencies maintain gazetteers containing the official names of places and/or the names that appear on map series. Examples include the U.S. Geological Survey's Geographic Names Information System (GNIS) and the National Imagery and Mapping Agency's Geographic Names Processing System (GNPS). Both of these are maintained in cooperation with the U.S. Board of Geographic Names (BGN). Many other examples could be cited -- for local areas, for other countries, and for special purposes. There is remarkable diversity in approaches to the description of geographic places and no standardization beyond authoritative sources for the geographic names themselves.

- Abstract
- Describes the experience of data conversion and migration at the libraries of the Home Office (HO) and the Dept. of the Environment (DoE), UK. Both HO and DoE libraries had changed from Anglo-American code cataloguing to AACR2 cataloguing in the mid-1970s. Both libraries were selective in identifying records for conversion initially to BLAISE-LOCAS. Conversion to integrated library systems from BLAISE-LOCAS MARC tapes produced problems in both libraries with location/holdings fields which were largely resolved at HO, but not resolved at DoE. HO experienced problems converting to a system with fixed field lengths. HO converted subject keywords to form a rudimentary, non-standard thesaurus which required the addition of Broader Term and Narrower Term to meet the challenge of computerized searching. DoE converted a non-thesaurus subject index to an authority file, but continued to maintain the index on a stand-alone DataEase application for use by cataloguers. Neither library converted acquisitions data

- Abstract
- Analyzes user requests resulting in zero hits for author searches in online catalogs. Discusses the need for bibliographic records relating to a name to brought together under one form of the name and the need for cross references from variant forms of the name. Presents data which prove that linked bibliographic/authority files and the availability of see references online in the OPAC reduce the number of times that author searches produce zero hits

- Abstract
- The requirement for and development of the Anglo-American Authority File (AAAF) is described. The mechanics of its production and updating are indicated and its role within British Library cataloguing practice examined. Further developments of the file are discussed and developments through IFLA towards international exchange of authority data are described, indicating both opportunities and difficulties. The EC-funded project AUTHOR is outlined and, finally, the British Library's work with the Library of Congress and American Library Association on extending LCSH to works of fiction is described.

- Abstract
- A sample was taken of the name and title provisional, or minimal level, authority records created by Blackwell North America, Inc., during its authority control processing in preparation for the implementation of NOTIS at the State Univerity of New York at Buffalo Libraries. Analysis of the sample showed that approximately 10 % of theses provisional records were created unnecessarily, while approximately 7 % had Library of Congress Name Authority File recordsestablished since the vendor's work was completed. The remaining 83 %, which will require original authority work in order to be upgraded to 'full' status, are categorized in such a manner as to determine the best approach to achieving the libraries' goal of absolute authority control.
