- Abstract
- After a fundamental examination of the phenomenon of time, this paper presents the history, authority, and structure of period subdivisions and chronological terms in the three subject heading languages LCSH (Library of Congress Subject Headings), RAMEAU (Répertoire d'Autorité Matière Encyclopédique et Alphabétique Unifié), and RSWK (Regeln für den Schlagwortkatalog). Their usefulness in online searching is demonstrated using the online catalogs of the Library of Congress, the Bibliothèque nationale de France, and the Deutsche Bibliothek and is compared to the search options in selected digital encyclopedias (Encyclopaedia Britannica, Encarta, Brockhaus-Enzyklopädie). The author develops a model for common time retrieval across all three online catalogs, outlines the conditions for that model (time period code, chronological code, and chronology authority file), and proposes a search interface.

- Abstract
- Library of Congress Subject Headings (LSCH), which celebrated its 100th birthday in 1998, is the largest cataloging and indexing language in the world for the indication of the topics and formats of books and similar publications. It consists of a controlled list of main headings, many with subdivisions, with a rich system of cross references. It is supported by the U.S. government, and undergoes systematic revision. In recent decades its managers have begun to confront challenges such as biased terminology, complicated syntax (how terms are put together to form headings), and effective displays in electronic media. Many suggestions have been made for its improvement, including moving to a fully faceted system.

- Abstract
- Although subject hierarchies are widely used to index document collections, few tools leverage their structure to facilitate collection browsing. This is mostly due to the complexity of such structures that include thousands of nodes. This paper proposes a new approach to simplify subject hierarchies based on the distribution of documents among the nodes. A random walk algorithm simulates the route of a user within the hierarchy, under the assumption that the user is attracted by the most populated nodes. Poorly visited nodes can be identified and eliminated, leaving a structure containing only the nodes that best represent the content of the collection. Experiments on a collection indexed using the Library of Congress Subject Headings (LCSH) show that, as compared to the state-of-the-art simplification method, the random walk-based approach gives access to a larger part of the collection for the same structure size, and offers more flexibility to customize the complexity of thestructure.

These papers were writeen in 1986 and are all about LCSH on magnetic tape. Gads!

- Abstract
- The Library of Congress Subject Headings (LCSH) is a subject structure used to index large collections throughout the world. Browsing a collection through LCSH is difficult using current on-line tools in part because they are inadequately integrated with information collections. Users of these LCSH browsing tools are expected to find a promising LCSH string before using it to search for the information itself; many users do not have the patience for such a two-step process. This article proposes a method to fully integrate a specific collection in its subset of the LCSH hierarchy in order to facilitate LCSH browsing as well as information retrieval. Techniques are described to match LCSH strings assigned to the collection with an established string from the authority records, and build their specific LCSH hierarchy. The resulting subset of LCSH structure is described in terms of its size and broader/narrower term statistics, and implications for browsing and information retrieval are discussed. The results of this research have implications for institutions wishing to further capitalize on existing LCSH organization investments for the purpose of subject browsing and information retrieval.
