- 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
- 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
- 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
- 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
- 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
- Purpose - The purpose of this paper is to present a general overview with up-to-date information on the Universal Decimal Classification (UDC) use worldwide. Design/methodology/approach - The research combined e-mail interviews with LIS professionals in 208 countries, literature research and information obtained from UDC distributors/publishers (AENOR, BSI, UDC Consortium). The following categorisation of UDC use was offered: A - dominant system; B - used in some kind of libraries only; or C - rarely used. Findings - The paper finds that, of the 208 countries contacted and researched through the literature in 2004-2006, the UDC was found to be used in 124 (60 per cent) of these. In 34 (28 per cent) of the countries researched (in Europe, Asia and Africa), UDC is the main classification system used across national information networks. In 45 (36 per cent) of the countries it is used in certain kinds of libraries. In the remaining 45 (36 per cent) of the countries it is used rarely, in only a few libraries or information centres. Research limitations/implications - It was beyond the scope of this research to provide any information regarding the actual number of institutions using UDC in a given country or to give an estimate of the size and number of document collections organised by it. Although a decline in UDC use since the 1980s was reported from a number of countries, it was not possible to measure this accurately. Practical implications - The interest shown for using UDC in the organisation of digital collections, information exchange and cross domain and cross collection resource discovery depends on accurate knowledge of its actual usage worldwide. This gives a measure of its global importance and verifies its credentials as an indexing standard. This research, which attempted wider and more systematic coverage than previous surveys, should help clarify the status of UDC and its potential use in the networked environment. Originality/value - The paper provides up-to-date information on the presence of the UDC system across countries and languages.

- Abstract
- A work in progress. An analysis of the handling of the domain "environmental science" in three universal classification schemes. Attention is given to problems of primary location, interdisciplinarity, degree of scatter, tenninology and structure of the domain. 1. Introduction Many traditional tools for organizing and providing access to recorded knowledge have become increasingly inadequate in responding to the changing requirements for effective organization and retrieval. The universal classification systems have been primary targets for criticism. In varying degrees they have been proven too rigid and somewhat limited as tools of modern knowledge organization. These inadequacies can be attributed to several significant factors - the changing nature of knowledge itself, the emergence of new domains, the realignment of old ones, and the development of very large databases. Also, more and more, as new technologies become available, there is increasing emphasis an the retrieval of facts as opposed to the retrieval of whole documents. In particular, the Internet encourages information seeking at a macro-level while the major universal systems were designed to organize information at a macro level. Moreover, there is a growing body of research and practical application aimed at improving the situation. This papers examines three of the best known universal classification systems the Dewey Decimal (DDC), Universal Decimal (UDC) and Library of Congress (LCC) classification systems in the light of their ability to respond to the changing nature of information itself. Recent research is briefly examined for its applicability to them. Environmental science, a recently emerging domain, is used as a basis for the analysis.

- 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
- Der Grund für die Einführung der DDC war die Umstellung auf Freihand durch den damals bevorstehenden Umbau und Ausbau der Bibliothek. Durch die Errichtung von 3 Tiefgeschoßen war es möglich, das gesamte oberirdische Magazin für das Publikum zu öffnen, wodurch die Publikumsflächen von vorher weniger als 200 m**2 auf nun 2200 m**2 ausgeweitet werden konnten. Zur Ausgangssituation: Wir hatten damals eine Freihand-Bibliothek im Umfang von einigen tausend Nachschlagewerken im Lesesaal, die wir einige Jahre zuvor - nach einem Umbau des Lesesaals - grob nach der 3-stelligen DDC aufgestellt hatten. Aber im Grunde genommen war das Thema Freihand für uns vollkommenes Neuland.

- 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.

- Abstract
- Toward the end of the nineteenth century, Paul Otlet and Henri LaFontaine of Belgium initiated the compilation of an index to all recorded knowledge. Instead of an alphabetical file, they decided to adopt a classified arrangement. For the basis of such an arrangement, they turned to the Dewey Decimal Classification, a system which was gaining wide acceptance in American libraries. With permission secured from Melvil Dewey to expand the system to include details required for an indexing tool, Otlet and LaFontaine began developing what was to become the Universal Decimal Classification (UDC). Following the establishment of the Institut International de Bibliographie (IIB), later the Fédération Internationale de Documentation (FID), in 1895, work an the universal index and the classification scheme proceeded under its aegis. In 1905, the classification scheme was published as the Manuel du Répertoire bibliographique universel. While the initial, ambitious project of the universal index was abandoned, the classification scheme itself was widely adopted, particularly in special libraries in Europe. A second edition was published in 1927-1933 under the title Classification décimale universelle. The development and maintanance of the scheme continued with the support of the FID. In the course of its development, the UDC moved further and further away from its prototype, the Dewey Decimal Classification. One of the major differences between the two systems is the use of relators in UDC. The notation adopted by Melvil Dewey for his scheme is a hierarchical one; in other words, the notation reflects the hierarchical relationships among subjects. However, it does not display the relationships among the facets, or aspects, of a particular subject. Furthermore, the use of auxiliaries in the Dewey Decimal Classification, beginning with the form subdivisions and gradually expanding to include geographic subdivisions and finally other auxiliaries in the most recent editions, has been relatively restricted. As an indexing tool, Otlet and LaFontaine felt that their system needed commonly applicable auxiliaries which they called "determinatives."` To this end, a series of special symbols were introduced into the system for the purpose of combining related subjects and indicating different facets or aspects of the main subject. The use of these symbols, called relators, with the auxiliaries has rendered the Universal Decimal Classification a synthetic scheme. In this respect, the UDC has moved much more rapidly than the Dewey Decimal Classification toward becoming a faceted classification. In the following paper, Henry V. Hopwood, a Senior Assistant at the British Patent Office Library during the 1900s, explains the use and rationale of relators, or "marks," as he calls them, in the Universal Decimal Classification.

- Abstract
- This paper takes a second look at three prevailing main themes in knowledge organization: i) the academic disciplines as the main structural principle; ii) the fiction/non-fiction distinction; and iii) the appropriate unit of analysis in online retrieval systems. The history and origin of bibliographic classification [Dewey, Bliss, Mills, Beghtol] are discussed from the perspective of pragmatist philosophy and social studies of science [Kuhn, Merton, Reich]. Choices of structural principles in different schemes are found to rely on more or less implicit philosophical foundations, ranging from rationalism to pragmatism. It is further shown how the increasing application of faceted structures as basic structural principles in universal classification schemes [DDC, UDC] impose rationalistic principles and structures for knowledge organization which are not in alignment with the development of knowledge in the covered disciplines. Further evidence of rationalism in knowledge organization is the fiction/non-fiction distinction, excluding the important role of artistic resources for, in particular, humanistic research. Finally, for the analysis of appropriate bibliographic unit, it is argued that there is a need to shift towards a semiotic approach, founded on an understanding of intertextuality, rather than applying standard principles of hierarchical decomposition of documents. It is concluded that a change in classification research is needed, founded on a more historical and social understanding of knowledge
