The author discusses the value and importance of using short extracts from classification tables to support subject access management. While detailed classification is time consuming, complex and costly, the classification of documents into broader classes is a simpler and easier way of achieving meaningful and useful subject organization. The paper outlines the role of this type of classification use in bibliographic listings, in the organization and representation of physical documents, in the presentation of web resources, in statistical reports in collection development and use, and, last but not least, in information integration in a networked environment. This approach of subject classification is illustrated by the Slovenian union catalogue COBISS/OPAC in which a standardized set of UDC codes is used. The author emphasizes the importance of this outline for the homogeneity and continuity of the use of UDC in Slovenia and explains how this may be weakened by the changes in the top level of UDC.

The UDC class 1 Philosophy. Psychology has remained unchanged for more than forty years. The most obvious problem with the class is an anachronistic intercalation of psychology in the middle of the class of philosophy which is one of the still uncorrected remainders of structural problems inherited from Dewey Decimal Classification.

UDC Editorial Workshop is a meeting of the UDC Editors and UDC Advisory Board and invited guests. The 2011 workshop took place on 21 September 2011, in the Koninklijke Bibliotheek in The Hague and was attended by twenty participants. The focus of the workshop was on the structural issues of the UDC scheme, in particular with respect to the ongoing faceting of the scheme and the way in which this influences the UDC content revision process.

This paper explores the use of UDC in libraries and information centers of Delhi. The information presented here is part of the larger data set collected by the author while compiling the Delhi libraries web directory. The survey, conducted through library visits and questionnaires, shows that in Delhi there are sixty four libraries using various editions of UDC. These include libraries of Defense Research and Development Organization (DRDO), Council of Scientific and Industrial Research (CSIR), Indian Council of Agricultural Research (ICAR), as well as libraries of the Judiciary system situated in Delhi such as Supreme Courts of India, High Courts of Delhi and Districts courts of Delhi. Some libraries of national importance such as Indian Institute of Technology, National Agricultural Library, National Medical Library, National Science Library, are also using the UDC.

The article provides a short overview of the history of the UDC use in Lithuania and current project of UDC translation in Lithuanian.

Dewey’s Decimal Classification was introduced in India in 1915 by Asa Don Dickinson (1876-1960), a student of Melvil Dewey, on his appointment as Librarian in Punjab University, Lahore. Soon after, India became its largest user of the system in Asia. It is, however, unknown when and how UDC was first used in India. The earliest reference to UDC can be found in Ranganathan’s classic Prolegomena to library classification (1937), wherein he made a comparative study of the then existing classification systems in order to derive some normative principles of classification,but more so to demonstrate the supremacy of his own system, Colon Classification (CC). Nevertheless, it is known that some libraries were using UDC by the early 1950s.

There are two main classification systems used in Ukraine, such as Universal Decimal Classification (UDC) and Library Bibliographic Classification (LBC). UDC is used mainly in libraries of higher education institutions, scientific, scientific-and-technical, medical, agricultural and other specialized libraries, information centres and publishing houses. The paper introduces recent developments (2009-2010 period) regarding UDC in Ukraine.

In Russia the most widely used library classifications are the national scheme BBK (Library Bibliographic Classification) and the UDC. The Russian National Public Library for Science and Technology is the leading scientific and technical library in Russia. It has a long tradition of classifying literature according to the UDC which started back in 1963. For many years the Library provided support for classification by UDC and also assisted in the areas of research and information while also acting as a supervisor in the matter of indexing for the network of scientific and technical libraries of Russia and the USSR. The paper describes the use of UDC in the environment of the electronic catalogue and the automated library system.

The paper presents and describes the work on the revision of the zoology of vertebrates, which is published in E&C 32 and introduced in UDC MRF 2010. This is the first stage of a larger project of revision, correction and update affecting all tables related to systematics (zoology, botany, microbiology and virology) to be undertaken from 2011-2013. The first part of the paper briefly introduces the current systems of classification of living and extinct beings, and explains how different perspectives with respect to the arrangement of biological entities have been reflected (or not) in the UDC schedules. The second part gives an overview of problems detected in UDC prior to this revision and explains solutions that were implemented in UDC MRF 2010 indicating tools and methods used in this work.

The author of this report has been charged by the UDC Consortium to study the possibility of a revision of class 1 Philosophy. Psychology, of the Universal Decimal Classification. In order to explore the situation and discuss possibilities of revising Class 1, an informal working group was formed at the beginning of 2009 by the author of this report. Members of the working group agreed that the revised class should have a fully faceted structure. One basic step in the revision study is to identify the facets needed to express the contents of philosophical knowledge appropriately. To this purpose, one starting point was provided by examination of the facets of philosophy in existing classifications, in particular BC2. The next steps will be to pay more attention to the details of classes and subclasses, and to the update of terminology and presentation of the schedule. All these components are expected to be included in a final proposal for revision of class 1.
