- Abstract
- The Library of Congress Classification (LCC), originally designed for classifying the Library's own collection, is now used in a wide range of libraries, both in the United States and abroad. This entry recounts its history and development from its genesis to the present time, leading up to an explanation of LCC structure, tables, and notation. It then considers the system's potential for wider application in the online age, through speculation on using LCC as a tool for (a) partitioning large files; (b) generating domain-specific taxonomies; and (c) integrating classification and controlled subject terms for improved retrieval in the online public access catalog (OPAC) and the Internet. Finally, analyzing both its strong and relatively weak features, it addresses the question of whether in its current state LCC is in all respects ready for playing such roles

- Abstract
- In 2003, OCLC published Dewey Decimal Classification and Relative Index, Edition 22 (DDC 22), in print and Web versions. The changes and updates in the new edition reflect a modern view of knowledge structures and address the general needs of Dewey users. The content of DDC 22 has been shaped by a number of social, geopolitical, and technical trends. The World Wide Web has provided a vehicle for more frequent distribution of updates to the DDC, and a medium for direct communication with Dewey users around the world. In addition to updating the system itself, other strategies are needed to accommodate the needs of the global Dewey user community. Translation of the system is one approach; another is mapping. Mapping terminology to the DDC is a strategy for supporting effective local implementation of the system while maintaining the internal cohesiveness of the DDC. This paper explores the usefulness of mapping terminology from English-language general subject headings lists produced outside the U.S.

- Abstract
- Die ständig steigende Zahl an publizierter Information in immer neuen Formen verlangt besonders von Informations- und Dokumentationseinrichtungen immer präzisere Lösungen zur Erschließung dieser Informationen und ihrer benutzerfreundlichen Aufbereitung. Besonders im derzeitigen Zeitalter der Datenbanken und Online-Kataloge ist die Kombination von verbaler und klassifikatorischer Sacherschließung gefordert, ohne dabei die Verbindung zu den älteren, vielerorts noch (zumindest zusätzlich) in Verwendung befindlichen, Zettelkatalogen zu verlieren. Weltweit ist eine Vielzahl an verschiedenen Klassifikationen im Einsatz. Die Wahl der für eine Einrichtung passenden Klassifikation ist abhängig von ihrer thematischen und informationellen Ausrichtung, der Größe und Art der Bestände und nicht zuletzt von technischen und personellen Voraussetzungen. Auf Seiten der zu wählenden Klassifikation sind die Einfachheit der Handhabung für den Bibliothekar, die Verständlichkeit für den Benutzer, die Erweiterungsfähigkeit der Klassifikation durch das Aufkommen neuer Wissensgebiete und die Einbindung in informationelle Netze mit anderen Einrichtungen von entscheidender Bedeutung. In dieser Arbeit soll die Dewey Dezimalklassifikation (DDC) hinsichtlich dieser Punkte näher beleuchtet werden. Sie ist die weltweit am häufigsten benutzte Klassifikation. Etwa 200.000 Bibliotheken in 135 Ländern erschließen ihre Bestände mit diesem System. Sie liegt derzeit bereits in der 22. ungekürzten Auflage vor und wurde bisher in 30 Sprachen übersetzt. Eine deutsche Komplettübersetzung wird im Jahre 2005 erscheinen. Trotz teils heftig geführter Standardisierungsdebatten und Plänen für die Übernahme von amerikanischen Formalerschließungsregeln herrscht in Bezug auf die Sacherschließung unter deutschen Bibliotheken wenig Einigkeit. Die DDC ist in Deutschland und anderen europäischen Ländern kaum verbreitet, sieht von Großbritannien und von der Verwendung in Bibliografien ab. Diese Arbeit geht demzufolge auf die historischen Gründe dieser Entwicklung ein und wagt einen kurzen Ausblick in die Zukunft der Dezimalklassifikation.

- Abstract
- This paper aims at exploring the changes in the role and representation of information retrieval languages, particularly the UDC system in the digital, online environment and the Internet. The Totalzoom Technology takes a different approach, with the help of which even a lay user can easily navigate in the "informational space". This system follows the free associative nature of human thinking. Technically, it works with the wide degree of freedom afforded by a logical-associative network, coupled with a hierarchical search tree as an inner auxiliary structure.

- 1. Introduction The use of classical classification methods are a strong tradition in Hungary. One of the most widespread systems is the Universal Decimal Classification (UDC). We can find it in every type of library and at various levels. Perhaps it is not an overstatement to say that every library has used the UDC at least once in its history, and most of them still use it. Such standardization has been very wide and desirable, although the UDC has not become as popular a system among users everywhere as it has in Hungary. Naturally there are other information retrieval languages, too. They have been used by many libraries, but generally these institutions build their own subject system, own thesaurus, etc. There have also been attempts at creating a Hungarian General Subject s, like a Library of Congress Subject Headings or Regeln für den Schlagwortkatalog. Another project was the KÖZTAURUSZ (Comprehensive Thesaurus for the Public Libraries) and the National Széchényi Library's thesaurus. To what do we owe such a variety of approaches? The typical answer of 15-20 years ago was that the UDC lacked flexibility, its codes could not readily be used in integrated library systems, its terms were out of date and not concrete enough, etc.

- Abstract
- To those outside the field of library science, the name Melvil Dewey (1851-1931) is virtually synonymous with library classification. To those in the field, Dewey has been recognized as the premier classification maker. His enormously successful system (i.e., successful in terms of the wide adoption of the system around the world for over one hundred years) has now undergone nineteen editions. The Dewey Decimal Classification has been translated into more than twenty languages and is the most widely adopted classification scheme in the world. Even in its earliest manifestations, the Dewey Decimal Classification contained features that anticipated modern classification theory. Among these are the use of mnemonics and the commonly applied standard subdivisions, later called "common isolates" by S. R. Ranganathan (q.v.), which are the mainstays of facet analysis and synthesis. The device of standard subdivisions is an indication of the recognition of common aspects that pervade all subjects. The use of mnemonics, whereby recurring concepts in the scheme are represented by the same notation, for example, geographic concepts and language concepts, eased the transition of the Dewey Decimal Classification from a largely enumerative system to an increasingly faceted one. Another significant feature of the Dewey Decimal Classification is the use of the hierarchical notation based an the arabic numeral system. To a large extent, this feature accounts for the wide use and success of the system in the world across language barriers. With the prospect of increasing online information retrieval, the hierarchical notation will have a significant impact an the effectiveness of the Dewey Decimal Classification as an online retrieval tool. Because the notation is hierarchical, for example, with increasing digits in a number representing narrower subjects and decreasing digits indicating broader subjects, the Dewey Decimal Classification is particularly useful in generic searches for broadening or narrowing search results. In the preface to the second edition of his Decimal Classification Dewey explained the features of his "new" system. The excerpt below presents his ideas and theory concerning the rational basis of his classification, the standard subdivisions, the hierarchical notation based an decimal numbers, the use of mnemonics, the relative index, and relative location. It also reflects Dewey's lifelong interest in simplified spelling.

- Abstract
- In the Internet information space, advanced information retrieval (IR) methods and automatic text processing are used in conjunction with traditional knowledge organization systems (KOS). New information technology provides a platform for better KOS publishing, exploitation and sharing both for human and machine use. Networked KOS services are now being planned and developed as powerful tools for resource discovery. They will enable automatic contextualisation, interpretation and query matching to different indexing languages. The Semantic Web promises to be an environment in which the quality of semantic relationships in bibliographic classification systems can be fully exploited. Their use in the networked environment is, however, limited by the fact that they are not prepared or made available for advanced machine processing. The UDC was chosen for this research because of its widespread use and its long-term presence in online information retrieval systems. It was also the first system to be used for the automatic classification of Internet resources, and the first to be made available as a classification tool on the Web. The objective of this research is to establish the advantages of using UDC for information retrieval in a networked environment, to highlight the problems of automation and classification exchange, and to offer possible solutions. The first research question was is there enough evidence of the use of classification on the Internet to justify further development with this particular environment in mind? The second question is what are the automation requirements for the full exploitation of UDC and its exchange? The third question is which areas are in need of improvement and what specific recommendations can be made for implementing the UDC in a networked environment? A summary of changes required in the management and development of the UDC to facilitate its full adaptation for future use is drawn from this analysis.

- Der dann folgende Vortrag von Joan Mitchell mit dem programmatischen Titel "Locality and universality in the DDC" gab zuerst einen Überblick über die laufenden Übersetzungsprojekte, bezogen auf die Ed. 22, nämlich: Französisch, Italienisch, Spanisch, Griechisch, Arabisch und Chinesisch. Bezogen auf die Abridged Ed. 14 außerdem: Hebräisch und Vietnamesisch. Sie erwähnte auch den Einsatz von Dewey bei internationalen Projekten wie der "World Digital Library". Der zentrale Punkt des Vortrags betraf dann den Spagat zwischen ,Localization and Interoperability', d.h. zwischen Anpassung an regionale Gegebenheiten (wie z.B. Unterschiede in den Bereichen des Rechts- und Erziehungssystems) auf der einen Seite und Festhalten an der Durchgängigkeit der Bedeutung über alle Sprachen und Kulturen hinweg. Wie auch Magda Heiner-Freiling in ihrem Vortrag hinwies, hat sich die amerikanisch geprägte DDC im Zuge der Übersetzungsprojekte zwar schrittweise den Bedürfnissen der Benutzer in anderen Erdteilen geöffnet, dennoch bestehen noch zahlreiche Schwierigkeiten. Das von Heiner-Freiling erwähnte Beispiel der Pädagogik zeigte aber auch, dass Vorsicht bei Alleingängen auf nationaler Ebene geboten ist, da z.B. im Zuge des Bologna-Prozesses auch in Europa amerikanische institutionelle Strukturen und Terminologie im Bildungswesen Einzug halten. Weitere Vorträge befassten sich mit der Arbeit an elektronischen Verfahren zur automatischen Analyse von DDC-Notationen (Ulrike Reiner aus Göttingen), mit der DDC-Übersetzungs-Software, die für die Übersetzung ins Deutsche entwickelt wurde und nun auch in allen anderen Sprachen im Einsatz ist (Peter Werling, Fa. Pansoft) bzw. mit der DDC-Suche in verschiedenen Webportalen (Lars G. Svensson, DNB). Der abschließende Vortrag von Magda Heiner-Freiling (DNB) ging dann wieder ins Programmatische mit dem Vorschlag, eine gemeinsame European DDC Users Group (EDUG) zu gründen, um gemeinsame Anliegen der europäischen Dewey-User, was z.B. die anfangs erwähnten Probleme in einzelnen Bereichen betrifft, gemeinsam gegenüber den amerikanischen Herausgebern zu vertreten, um so mehr Einfluss auf die künftige Entwicklung der DDC zu haben.
Wer sich näher für einzelne Themen interessiert, hat die Möglichkeit, auf der Homepage der Schweizer Nationalbibliothek die Präsentationsunterlagen der einzelnen Vorträge einzusehen (http://www.nb.admin.ch/slb/slb_professionnel/projektarbeit/00729/01615/01675/index.html?lang=de). Ziel des zweiten Tages war die Gründung einer europäischen DDC-Anwendergruppe zum Zweck der Vernetzung und Planung für die gemeinsame Entwicklungsarbeit. Anwesend waren Vertreterinnen der Nationalbibliotheken von Großbritannien, Deutschland, Frankreich, Schweden, Norwegen, Italien, Schweiz und Österreich sowie eine Vertreterin von OCLC. Eingeladen hatten die Nationalbibliotheken von Deutschland und der Schweiz. Vormittags wurde eine allgemeine Diskussion über die Ziele und Möglichkeiten einer solchen Anwendergruppe sowie allgemein über die Vorteile einer DDC-Anwendung in Europa diskutiert. Ziele von EDUG könnten sein: - Monitoring der europäischen DDC-Anwendungen - Kenntnis der unterschiedlichen Anwendungsregeln in den verschiedenen Ländern - Zugang auch zu den DDC-Übersetzungen in anderen Sprachen samt Expansionen - Zusammenarbeit beim Angebot von "built numbers" Zusammenarbeit mit OCLC als Vertreterin von europäischen Anliegen (die am Vortag ausführlich angesprochen worden waren) - Harmonisierung der Änderungen in den verschiedensprachigen Ausgaben (21./22. Ed., unterschiedliche Erweiterungen, anderer Sprachgebrauch) - Kooperation bei der Realisierung von technischen Plänen wie z.B. die automatische Klassifikation von Online-Dokumenten oder dem Mapping zu anderen Klassifikationssystemen - Weitergabe von Know-how und Erfahrungen an andere Interessierte Spontan wurden drei Arbeitsgruppen ins Leben gerufen, und zwar eine für technische Angelegenheiten und zwei inhaltliche für die kritischen Bereiche Recht und Erziehung. Nachmittags wurden die Satzungen von EDUG diskutiert und überarbeitet. Bei vielen Punkten wurde Übereinkunft erzielt. Einzelne Fragen blieben noch offen und sollen beim nächsten Treffen - wahrscheinlich im April 2008 in Frankfurt - endgültig fixiert werden."

- Abstract
- Es werden die Überlegungen im Zusammenhang mit der Einführung der Dewey-Dezimalklassifikation im deutschen Sprachraum dargestellt, wobei die künftige deutsche DDC-Ausgabe auf der Basis der 22. Auflage der Original-DDC im Mittelpunkt steht. Dringlich für eine deutsche Ausgabe sind neben Korrekturen und Expansionen für deutsche Sachverhalte, etwa im Bereich der geografischen Hilfstafel, die Schaffung eines deutschen Begriffsinventars für das Instrumentarium der DDC selbst und eine Integration der Terminologie der Schlagwortnormdatei, soweit das mit der Struktur einer Klassifikation vereinbar ist. Daneben kommt der über eine reine Übersetzung hinausgehenden Anpassung der Beispiele und Registereinträge der DDC an die Suchgewohnheiten deutschsprachiger Benutzer eine erhebliche Bedeutung zu.

- Abstract
- This paper presents the results of an exploratory study to determine literary warrant for topics in electronic resources. The classification numbers in Abridged Edition 14 were used as a starting point. Using the principles of abridgment and expansion in Dewey, a version of the DDC is defined that accommodates the topics found an three diverse Web sites that use Dewey: BUBL, Canadian Information By Subject, and KidsClick! The resulting classes are used to create a database for automated classification of Web resources.

- Abstract
- Analytico-synthetic and faceted classifications, such as Universal Decimal Classification (UDC) provide facilities to express pre-coordinated subject statements using syntactic relations. In this case, the relevance, in the process of UDC-based information retrieval, can be determined by extracting the meaning of the classmarks as precisely as is possible. The central question here is how the identification mentioned above can be supported by automatic means and an analysis of the structure of complex classmarks appears to be an obvious requirement. Many bibliographic sources contain complex UDC classmarks which are stored as simple text strings and on which it is very difficult to perform any meaningful information discovery. The paper presents results from a phase of ongoing research focused on developing a new platform-independent, machine-processable data format capable of representing the whole syntactic structure of the composite UDC numbers to support their further automatic processing. An algorithm that can produce the representation of the numbers in such a format directly from their designations has also been developed and implemented. The research also includes implementing conversion methods to provide outputs that can be employed by other software directly and, as a service, make them available for other software. The paper provides an overview of the solutions developed and implemented since 2015 and outlines future research plans.

- Rez. in: Knowledge organization 31(2004) no.2, S.112-114 (M.P. Satija) : "With nearly 130 years of eventful and checkered history, the Dewey Decimal Classification (DDC) is the oldest living yet thriving modern library classification. Having undergone 21 revisions, it is the most applied library classification structure all over the world. Apart from its use in libraries in more than 135 countries across six continents, many national and trade bibliographies use it for content organization. Furthermore, it is now making successful forays into the world of electronic documents and networked information. The print version of the 22nd edition was released in September 2003, two months later than the scheduled time of July 2003, and two months after the release of the electronic version, WebDewey. The period between print editions now seems settled to seven years as a matter of policy. As WebDewey, an the other hand, is updated an a quarterly basis, what really constitutes a new edition is problematic; edition is rolling, always in a flux without much fixity. The last half century, and more specifically the tenure of Benjamin A. Custer as editor (1956-1980; Editions 16-19), has been an era of structural changes in the DDC, backed by professional management and organizational planning. Custer was instrumental in not only resuscitating the system, but also in putting DDC back an the path of progress. His able successor, Dr. John P. Comaromi, edited the 20`h edition (1989) and ushered in a period of simplification and consolidation. Following the acquisition of Forest Press by OCLC in 1988, much more research has gone into making new editions of the DDC. The OCLC Office of Research has involved itself in classification research, especially in the harmonization of various knowledge classification systems and mapping of DDC numbers to subject headings, above all to make DDC capable of organizing electronic information of every sort. The acquisition of DDC by OCLC has also inaugurated an era of new products and services, along with organized marketing. DDC21 (1996) was a product of high IT, and the 22nd edition can safely be termed a child of network technology. It is indeed the first edition produced in the web environment. To stay abreast of current developments an knowledge practices, the editors relied an the Internet and electronic databases for new topics and terms. Editors and policy makes got constant feedback and suggestions via the Internet to add new features and to achieve accuracy and efficiency. In addition to the feedback and expert advice, this edition, as usual, is based an actual classification of three quarters of a million current books in the Decimal Classification Division of the Library of Congress since 1996.
Changes DDC22 is the second edition prepared by Joan S. Mitchell who took over as editor in 1993. It carries forward the policies and improvements started in DDC21, especially the onslaught an the Christian and western cultural blas in the schedules and tables. The plan for reducing Christian blas in 200 Religion, initiated in DDC21, has now been completed, with some additional provisions in 296 and 297. An outstanding change has been the abrogation of Table 7 Persons. The functions of Table 7 are now filled by using T1-08 and whatever notation is appropriate from 011-999. There are at least six places in the tables and 12 places in the schedules where the use of T7 was prescribed; what good the abolition of T7 has produced is not clear. In fact, it does make number building in some cases a bit circuitous, especially while using Table 3C. It has also resulted in the reuse of many DDC 21 numbers with new meanings. However, some numbers remain the same e.g., Social customs of artists 390.47 (both in DDC21 and DDC22). A few numbers have also become shorter in length. In compliance with the recommendations of D'Elia's survey, all works relating to directories of travel facilities such as hotels, lodges, Motels, inns, have been shifted to 910.46 and to 913/919 whereas 647.94 continues to be in place for general information about hotels. A common practice in previous editions, that is full class or extensive revisions (phoenix schedules), appear to have been discontinued in the preparation of DDC22. But minor changes are numerous. There are more than one thousand relocations and discontiuations of class numbers. Some 40 numbers have been reused. ... However, all these changes are not those projected as slated changes for DDC22 in the DDC21 (1996), namely in 520 Astronomy, 355-359 Military science, 636-639 Animal husbandry and 690 Buildings. Obviously the switch over to the DDC 22 will put less strain an libraries. There has been considerable improvement in the manual, now shifted to volume 1 of the print edition (pp. 1-182). Notes in the manual have been shortened by removing redundant information and by dividing them into smaller sections. Some information from the manual has been transferred to the schedules and tables, in the form of notes. The manual is now clearer and easier to read. Flow Charts, built-in numbers, and see also references should help classifiers achieve greater consistency. The relative index has been beefed up. With its 928 pages, it is 333 pages longer than the previous one, including new built-in numbers and many additional terms. The entry vocabulary is wide-based and current. DDC 22, the first edition of this millennium, has kept pace with the fast changing information environment to map and organize it squarely. To quote our friends at OCLC: knowledge is a big world, and they have organized it."

- Abstract
- The paper will give a short outline of the project DDC German. The project is not limited to a mere translation of DDC 22, but aims at the implementation of Dewey in the library networks of the German-language countries. Use of DDC mainly for retrieval purposes, not for shelving, leads to certain new aspects in classifying with Dewey which are described in detail and presented together with the German web service Melvil. Based an the German experience of cooperation and data exchange in the field of verbal indexing the paper develops some ideas an future Dewey cooperation between European and American libraries.

- Abstract
- Dewey Decimal Classification and Relative Index, Edition 22 (DDC 22) will be issued simultaneously in print and web versions in July 2003. The new edition is the first full print update to the Dewey Decimal Classification system in seven years-it includes several significant updates and many new numbers and topics. DDC 22 also features some fundamental structural changes that have been introduced with the goals of promoting classifier efficiency and improving the DDC for use in a variety of applications in the web environment. Most importantly, the content of the new edition has been shaped by the needs and recommendations of Dewey users around the world. The worldwide user community has an important role in shaping the future of the DDC.

- Abstract
- Bibliographic classification systems purport to organize the world of knowledge for information storage and retrieval purposes in libraries and bibliographies, both manual and online. The major systems that have predominated during the 20th century were originally predicated on the academic disciplines. This structural principle is no longer adequate because multidisciplinray knowledge production has overtaken more traditional disciplinary perspectives and produced communities of cooperation whose documents cannot be accomodated in a disciplinary structure. This paper addresses the problems the major classifications face, reports some attempts to revise these systems to accomodate multidisciplinary works more appropriately, and describes some theoretical research perspectives that attempt to reorient classification research toward the pluralistic needs of multidisciplinary knowledge creation and the perspectives of different discourse communities. Traditionally, the primary desiderata of classification systems were mutual exclusivity and joint exhaustivity. The need to respond to multidisciplinary research may mean that hospitality will replace mutual exclusivity and joint exhaustivity as the most needed and useful characteristics of classification systems in both theory and practice

- Abstract
- This book is an extension and total revision of the author's earlier Guide to the use of UDC. The original was written in 1993 and in the intervening years much has happened with the classification. In particular, a much more rigorous approach has been undertaken in revision to ensure that the scheme is able to handle the requirements of a networked world. The book outlines the history and development of the Universal Decimal Classification, provides practical hints on its application and works through all the auxiliary and main tables highlighting aspects that need to be noted in applying the scheme. It also provides guidance on the use of the Master Reference File and discusses the ways in which the classification is used in the 21st century and its suitability as an aid to subject description in tagging metadata and consequently for application on the Internet. It is intended as a source for information about the scheme, for practical usage by classifiers in their daily work and as a guide to the student learning how to apply the classification. It is amply provided with examples to illustrate the many ways in which the scheme can be applied and will be a useful source for a wide range of information workers
