Abstract

Many information professionals working in small units today fail to find the published tools for subject-based organization that are appropriate to their local needs, whether they are archivists, special librarians, information officers, or knowledge or content managers. Large established standards for document description and organization are too unwieldy, unnecessarily detailed, or too expensive to install and maintain. In other cases the available systems are insufficient for a specialist environment, or don't bring things together in a helpful way. A purpose built, in-house system would seem to be the answer, but too often the skills necessary to create one are lacking. This practical text examines the criteria relevant to the selection of a subject-management system, describes the characteristics of some common types of subject tool, and takes the novice step by step through the process of creating a system for a specialist environment. The methodology employed is a standard technique for the building of a thesaurus that incidentally creates a compatible classification or taxonomy, both of which may be used in a variety of ways for document or information management. Key areas covered are: What is a thesaurus? Tools for subject access and retrieval; what a thesaurus is used for? Why use a thesaurus? Examples of thesauri; the structure of a thesaurus; thesaural relationships; practical thesaurus construction; the vocabulary of the thesaurus; building the systematic structure; conversion to alphabetic format; forms of entry in the thesaurus; maintaining the thesaurus; thesaurus software; and; the wider environment. Essential for the practising information professional, this guide is also valuable for students of library and information science.

Abstract

A system of library classification that flashed across the inquiring mind of young Melvil Louis Kossuth Dewey (known as Melvil Dewey) in 1873 is still the most popular classification scheme.. The modern library classification begins with Dewey Decimal Classification (DDC). Melvil Dewey devised DDC in 1876. DDC has is credit of 128 years of boudless success. The DDC is being taught as a practical subject throughout the world and it is being used in majority of libraries in about 150 countries. This is the result of continuous revision that 22nd Edition of DDC has been published in July 2003. No other classification scheme has published so many editions. Some welcome changes have been made in DDC 22. To reduce the Christian bias in 200 religion, the numbers 201 to 209 have been devoted to specific aspects of religion. In the previous editions these numbers were devoted to Christianity. to enhance the classifier's efficiency, Table 7 has been removed from DDC 22 and the provision of adding group of persons is made by direct use of notation already available in schedules and in notation -08 from Table 1 Standard Subdivision. The present book is an attempt to explain, with suitable examples, the salient provisions of DDC 22. The book is written in simple language so that the students may not face any difficulty in understanding what is being explained. The examples in the book are explained in a step-by-step procedure. It is hoped that this book will prove of great help and use to the library professionals in general and library and information science students in particular.

Abstract

From classification to knowledge organization through subject indexing the field has been so rapidly growing that it is difficult to demarcate its boundaries. Knowledge organization is viewed in the sense of conglomeration of activities to sort and order knowledge, to acquire, ufilize, evaluate, represent and communicate knowledge for problem solving. It has been no simple matter to decide what should be included in and excluded from such a dictionary. Broadly speaking the terms an the following topics are included in the work : Knowledge, Epistemology, Concepts, Terminology and Vocabulary control ; Classification systems, their design, theory and practice of classification, Subject analysis; fundamental categories and facets, Content and Text analysis, Use of classification in online systems and an the web. Subject cataloguing : subject headings, Thesauri and alphabetical indexing languages : Keyword, chain and string indexes, Knowledge representation, Classification for access and retrieval, Cognitive aspects of information- seeking behaviour, Automatic classification, Descriptive cataloguing : Theory, kinds, levels, standards and codes, OPACs, all are covered in this work. Like any other such work of this sort, it is an electic compilation. The work proposes to be descriptive rather than prescriptive. Endeavour is to find brief simple, logical and consensual meaning of terms, and append brief description of a concept or an issue with explanation, examples and comments in a bottom up way. Some current topics denoted by phrases have also been included. At times it may give the look of a concise encyclopaedic dictionary. Terms fully describe concepts and methods, and may evoke some thoughts an current and classic issues in the field.

Abstract

This is a practical tool and comprehensive introduction to the use of controlled vocabularies. This authoritative and detailed volume presents readers with a 'how-to' guide to building controlled vocabulary tools, cataloguing and indexing cultural materials with terms and names from controlled vocabularies, and how to use vocabularies in search engines and databases to enhance discovery and retrieval online. "Introduction to Controlled Vocabularies" also features in-depth discussions on a number of topics, including: What are controlled vocabularies and why are they useful? Which vocabularies exist for cataloguing art and cultural objects? and how should they be used for indexing and retrieving? This book provides organizations and individuals with a practical tool for creating and implementing vocabularies as reference tools, sources of documentation, and powerful enhancements for online searching.

Rez. in: KO 32(2005) no.4, S.159-160 (G.J.A. Riesthuis): "This thesaurus is a revised edition of: ASIS thesaurus of information science and librarianship, edited by Jessica L. Milstead, 2nd ed. (1998). The change in the title is result of the change of the name of the ASIS (American Society of Information Science) into American Society for Information Science and Technology. Since 2002 the 2nd edition was used by Information Science Abstracts (now Information Science & Technology Abstracts). In the 2nd edition the goal of the thesaurus was formulated as "[include concepts from] information science and librarianship to a depth that will adequately support indexing in those fields with [...] related fields [...] computer science, linguistics and cognitive sciences [...]" (p. vii). The present editors started to update the thesaurus to reflect "the current state of the field and to implement it for indexing the Society's publications for the ASIS&T Digital Library" (p. v). The draft 3rd edition is used to index a great part of the Society's four publications. This means that the 3`1 edition is, more than its predecessors, based on literary warrant as far as this warrant is reflected in ASIS&T publications. The Netherlands have a descriptor, but Romania or Portugal not. The Bliss Bibliographic Classification is mentioned, but the far more often used Russian Library Bibliographical Classification (BBK) is missing. The thesaurus is presented in three parts: 1. An alphabetical listing of all terms. Here one finds the preferred and non-preferred terms with their relations denoted in the customary form (SN, BT, NT, RT, USE and UF). The ordering is word-byword. 2. An hierarchical display of the terms. This display contains the preferred terms only. 3. A permuted display of all terms. Unlike the 2nd edition, this list contains the non-preferred terms too. The thesaurus is like its predecessors a faceted one. There are seven main facets: 1. People and organizations, 2. Actions, events, and processes, 3. Physical objects, 4. Theoretical concepts and influences on information, 5. Information, information delivery formats and channels, 6. Methods of study, 7. Geographic information. The first five facets are subdivided in subfacets, the last have just one subfacet each. In total there arc 18 subfacets, referred to as "top terms" in the language of the thesaurus. This structure is not very different from the structure of the second edition, although the number of subfacets and the terminology has changed. There is one new facet "geographic information" with one subfacet: "countries and regions". In this facet one can see very clearly see that the thesaurus is based on literary warrant: only relatively few countries arc mentioned. The facet "methods of study" is expanded strongly. Under each of the top terms additional concepts are presented in a hierarchical structure. The maximum depth of the hierarchy is nine, although most subfacets have no more than four or five levels. The record for the "bibliometrics" entry shows clearly the changes. The domain and the main structure have not changed, but narrower terms not previously mentioned are added."
