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 summary of a survey of the use of the DDC in libraries of the United States and Canada is presented. (5% of alle libraries in the United States and Canada use DDC; of these are at least 75% use the most recent full or abridges edition. Librarians wish to have DDC revised continuously, but they do not want the meanings of numbers changed. Any assistance that can be provided in the application of DDC is welcome. Most of the larger libraries do not believe zhat the current index provides sufficient assistance. Divisions needing revision are listed with an index number reflecting priority. DDC is seen to be warmly regarded by librarians in general and by public service librarians in particular

Abstract

This study makes recommendations to adapt and expand the class Religion (200) of the Dewey Decimal Classification (DDC) for libraries in nations, particularly Korea, where religious diversity predominates. It contracts the classes on Christianity, 220-280, into one class, 220, and allows for local Korean emphasis so that religions of Asian, and especially East Asian, origin are given preferred treatment. It relocates Buddhism and other religions of Asian origin into separate divisions, 230 and 240, respectively. The recommendations maintain the basic system and order of DDC. Whenever possible, they adhere to the Korean Decimal Classification in the arrangement of religions of Asian origin. Because the options for religions other than Christianity in DDC are to give preferred treatment to a specific religion, this article tries to generalize the idea to suggest an option in DDC as Option F for "> 292-299 Religions other than Christianity", for other nations in the world having similar situations. It says: "Contract the Bible and Christianity in 220-280 into 220, and then class other religions to give preferred treatment in 230-280, respectively, following the order in DDC. In that case, the number "2" should be inserted in the second digit of the Bible and Christianity, e.g., the Bible 222, Jesus Christ & his family 223.2, and Puritanism 228.59."

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

Most Swedish libraries use a Swedish classification scheme called SAB, but a switch to Dewey Decimal Classification (DDC) is under consideration. The question of a Swedish switch to DDC was treated as part of a Catalogue Survey, conducted during 2006. Summarising the study, there is a lot to be said for a Swedish switch to DDC. If a switch became reality, mappings between SAB and DDC would play a crucial role as an aid both for librarians and library users. The article describes a project where a DDC arrangement of the Swedish National Bibliography should be achieved through mapping of the captions in the SAB arrangement. The methodology used is described, and problems are discussed. The article includes a comparison of DDC numbers achieved through mapping and manually added DDC numbers in a sample of bibliographic records. Future plans for DDC in Sweden are also discussed.

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

Seeking to document the extent to which libraries of four-year colleges and universities have adopted the LCC system, this study surveys the classification systems used by the libraries of 1.160 accredited four-year-colleges and universities. The LC system is presently being used by more than half of these libraries; however, throughout 1968-71 the "trend to LC" clearly lost momentum. Data are provided on the extent to which the Library of Congress and The DDC systems were used in 1967 and 1971 by libraries of various sizes and categories

Abstract

The origin of the abridged edition of the Dewey system goes back to 1894 when an outline of 192 pages based on the full 5th Edition (1894) was issued for small public and school libraries of North America. New editions have appeared regularly following closely the publication of new full editions. An abridged version, which is always in one volume, comprises an introduction, schedules, four tables (namely 1, 2, 3 and 4) only, and the relative index and other minor features of the full edition, and has shorter numbers. Abridged 15 is a logical abridgement of the DDC23 (2011) and is a product of a new approach to development of an abridged edition of the DDC. Its content has been derived from the DDC database applying a set of rules to extract the edition using the new (2010) version of the editorial support system. The revision process has been informed by interaction with an always widening and diversified Dewey community at home and abroad. It aims to improve the currency of the schedules continuing to serve as shelving tool while recognizing its 'other' uses as a spinoff of its simplicity and inexpensiveness.

Abstract

I am pleased to be included as part of this workshop. My contribution comes from my research and working with national bibliographies around the world, not from my expertise with the Dewey Decimal Classification system. With that disclaimer, I am ready to share my observations and experience in how national bibliographies and national bibliographic services use the DDC in national bibliographies, including a case study of the making of the Namibia National Bibliography

Abstract

This paper explores the feasibility of using the Universal Decimal Classification's revised religion scheme as the framework for an alternative view of 200 Religion in the Dewey Decimal Classification, and as a potential model for future revision. The study investigates the development of a top-level crosswalk between the two systems, and a detailed mapping using Buddhism as a case study.

Abstract

Nearly 25 years have elapsed since the last comprehensive measure of the percentage of academic libraries that employ the Dewey and Library of Congress systems of classification. To provide updated statistics, the researchers surveyed all 3793 academic libraries via their online catalogs. The findings indicate that the use of Dewey has declined over the past four decades. Teachers' Colleges and Community Colleges in particular have higher rates of Dewey use than large research or professional universities. This information may help support academic library reclassification decisions.

Abstract

Though several studies have been published on the topic of reclassification of academic library collections over the past eight decades since it first gained popularity, none have explored the preferences of academic library employees toward classification schemes beyond a merely superficial level. The preferences of library employees must serve some role in organizational decision-making. By distributing a mixed-methods survey to academic library employees across the United States, the researchers in the present study provide insight into employee preferences. The findings of the study may provide insight into library trends and the future of library classification schemes.

Abstract

Critical race theory is introduced as a potentially useful approach to the evaluation of bibliographic classification schemes. An overview is presented of the essential elements of critical race theory, including clarifications of the meanings of some important terms such as "race" and "social justice." On the basis of a review of existing conceptions of the just and the antiracist library service, a rationale is presented for hypothesizing that critical race theory may be of use to the library and information sciences. The role of classification schemes as information institutions in their own right is established, and the Dewey Decimal Classification is introduced as the case to be studied. The challenges faced by classification-scheme designers in the construction and reconstruction of racerelated categories are reviewed; and an analysis is presented of one sense in which it might be suggested that recent (2003) revisions in one of the DDC's tables appear not to meet those challenges wholly successfully. An account is given of a further sense in which adoption of a critical race-theoretic approach has the more radical effect of calling into question a fundamental decision recently taken to "deracialize" the DDC. In conclusion, an assessment is made of critical race theory as a framework for evaluating library classification schemes.

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

The paper describes the efforts of three national libraries to use the DDC to improve access in German to the national bibliographies of Switzerland, Germany and Austria. The reasons that led to the use of the DDC for the organisation of the bibliographies and the difficulties in adopting a common approach will be explained. The paper will deal with the approach of using the Second Dewey Summary and the adaptations made to suit the bibliographic requirements of each country's bibliography. The presentation will also explain the challenges of incorporating German requirements in the new outline of the different series of the Deutsche Nationalbibliograpfie and will show how these were successfully resolved.

Abstract

The spread of DDC in the UK can be traced to networking in the 1870s between the librarians of the new municipal free libraries and the American librarians who were promoting new ideas through conferences and associations. Manchester Free Library was particularly influential in the development of the library service in the UK. The first use of DDC seems to have been at Manchester, as a result of networking at the first Conference of Librarians in 1877. This interest in DDC in Manchester therefore significantly contributed to the acceptance of DDC as the standard scheme for UK public libraries. Traditions of networking and cooperation are illustrated in this history - just as they were exemplified by Magda Heiner-Freiling in her project DDC German.

Abstract

This entry discusses the Dewey Decimal Classification's value proposition as a general knowledge organization system in terms of basic design, history, ongoing development, translations, mappings, applications, and research. The authors conclude with prospects for use of the DDC inside and outside of libraries.
