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.

Rez. in: JASIST 55(2004) no.2, S.178-179 (M.-Y. Kan): "In their latest book, Chowdhury and Chowdhury have written an introductory text an digital libraries, primarily targeting "students researching digital libraries as part of information and library science, as well as computer science, courses" (p. xiv). It is an ambitious work that surveys many of the broad topics in digital libraries (DL) while highlighting completed and ongoing DL research in many parts of the world. With the revamping of Library and Information Science (LIS) Curriculums to focus an information technology, many LIS schools are now teaching DL topics either as an independent course or as part of an existing one. Instructors of these courses have in many cases used supplementary texts and compeed readers from journals and conference materials, possibly because they feel that a suitable textbook has yet to be written. A solid, principal textbook for digital libraries is sorely needed to provide a critical, evaluative synthesis of DL literature. It is with this in mind that I believe Introduction to Digital Libraries was written. An introductory text an any Cross-disciplinary topic is bound to have conflicting limitations and expectations from its adherents who come from different backgrounds. This is the rase in the development of DL Curriculum, in which both LIS and computer science schools are actively involved. Compiling a useful secondary source in such Cross-disciplinary areas is challenging; it requires that jargon from each contributing field be carefully explained and respected, while providing thought-provoking material to broaden student perspectives. In my view, the book's breadth certainly encompasses the whole of what an introduction to DL needs, but it is hampered by a lack of focus from catering to such disparate needs. For example, LIS students will need to know which key aspects differentiate digital library metadata from traditional metadata while computer science students will need to learn the basics of vector spare and probabilistic information retrieval. However, the text does not give enough detail an either subject and thus even introductory students will need to go beyond the book and consult primary sources. In this respect, the book's 307 pages of content are too short to do justice to such a broad field of study.
This book covers all of the primary areas in the DL Curriculum as suggested by T. Saracevic and M. Dalbello's (2001) and A. Spink and C. Cool's (1999) D-Lib articles an DL education. In fact, the book's coverage is quite broad; it includes a Superset of recommended topics, offering a chapter an professional issues (recommended in Spink and Cool) as well as three chapters devoted to DL research. The book comes with a comprehensive list of references and an index, allowing readers to easily locate a specific topic or research project of interest. Each chapter also begins with a short outline of the chapter. As an additional plus, the book is quite heavily Cross-referenced, allowing easy navigation across topics. The only drawback with regard to supplementary materials is that it Lacks a glossary that world be a helpful reference to students needing a reference guide to DL terminology. The book's organization is well thought out and each chapter stands independently of the others, facilitating instruction by parts. While not officially delineated into three parts, the book's fifteen chapters are logically organized as such. Chapters 2 and 3 form the first part, which surveys various DLs and DL research initiatives. The second and core part of the book examines the workings of a DL along various dimensions, from its design to its eventual implementation and deployment. The third part brings together extended topics that relate to a deployed DL: its preservation, evaluation, and relationship to the larger social content. Chapter 1 defines digital libraries and discusses the scope of the materials covered in the book. The authors posit that the meaning of digital library is best explained by its sample characteristics rather than by definition, noting that it has largely been shaped by the melding of the research and information professions. This reveals two primary facets of the DL: an "emphasis an digital content" coming from an engineering and computer science perspective as well as an "emphasis an services" coming from library and information professionals (pp. 4-5). The book's organization mirrors this dichotomy, focusing an the core aspects of content in the earlier chapters and retuming to the service perspective in later chapters.
Chapter 2 examines the variety and breadth of DL implementations and collections through a well-balanced selection of 20 DLs. The authors make a useful classification of the various types of DLs into seven categories and give a brief synopsis of two or three examples from each category. These categories include historical, national, and university DLs, as well as DLs for special materials and research. Chapter 3 examines research efforts in digital libraries, concentrating an the three eLib initiatives in the UK and the two Digital Libraries Initiatives in the United States. The chapter also offers some details an joint research between the UK and the United States (the NSF/JISC jointly funded programs), Europe, Canada, Australia, and New Zealand. While both of these chapters do an admirable job of surveying the DL landscape, the breadth and variety of materials need to be encapsulated in a coherent summary that illustrates the commonality of their approaches and their key differences that have been driven by aspects of their collections and audience. Unfortunately, this summary aspect is lacking here and elsewhere in the book. Chapter 2 does an admirable job of DL selection that showcases the variety of existing DLs, but 1 feel that Chapter 3's selection of research projects could be improved. The chapter's emphasis is clearly an UK-based research, devoting nine pages to it compared to six for EU-funded projects. While this emphasis could be favorable for UK courses, it hampers the chances of the text's adoption in other courses internationally. Chapter 4 begins the core part of the book by examining the DL from a design perspective. As a well-designed DL encompasses various practical and theoretical considerations, the chapter introduces much of the concepts that are elaborated an in later chapters. The Kahn/Wilensky and Lagoze/Fielding architectures are summarized in bullet points, and specific aspects of these frameworks are elaborated on. These include the choice between a federated or centralized search architecture (referencing Virginia Tech's NDLTD and Waikato's Greenstone) and level of interoperability (discussing UNIMARC and metadata harvesting). Special attention is paid to hybrid library design, with references to UK projects. A useful summary of recommended standards for DL design concludes the chapter.
Chapters 5 through 9 discuss the basic facets of DL implementation and use. Chapter 5, entitled "Collection management," distinguishes collection management from collection development. The authors give source selection criteria, distilled from Clayton and Gorman. The text then discusses the characteristics of several digital sources, including CD-ROMs, electronic books, electronic journals, and databases, and elaborates an the distribution and pricing issues involved in each. However, the following chapter an digitization is quite disappointing; 1 feel that its discussion is shallow and short, and offers only a glimpse of the difficulties of this task. The chapter contains a listing of multimedia file formats, which is explained clearly, omitting technical jargon. However, it could be improved by including more details about each fonnat's optimal use. Chapter 7, "Information organization, " surveys several DLs and highlights their adaptation of traditional classification and cataloging techniques. The chapter continues with a brief introduction to metadata, by first defining it and then discussiog major standards: the Dublin Core, the Warwick Framework and EAD. A discussion of markup languages such as SGML, HTML, and XML rounds off the chapter. A more engaging chapter follows. Dealing with information access and user interfaces, it begins by examining information needs and the seeking process, with particular attention to the difficulties of translating search needs into an actual search query. Guidelines for user interface design are presented, distilled from recommendations from Shneiderman, Byrd, and Croft. Some research user interfaces are highlighted to hint at the future of information finding, and major features of browsing and searching interfaces are shown through case studies of a number of DLs. Chapter 9 gives a layman's introduction to the classic models of information retrieval, and is written to emphasize each model's usability and features; the mathematical foundations have entirely been dispensed with. Multimedia retrieval, Z39.50, and issues with OPAC integration are briefly sketched, but details an the approaches to these problems are omitted. A dissatisfying chapter an preservation begins the third part an deployed DLs, which itemizes several preservation projects but does not identify the key points of each project. This weakness is offset by two solid chapters an DL services and social, economic, and legal issues. Here, the writing style of the text is more effective in surveying the pertinent issues. Chowdhury and Chowdhury write, " The importance of [reference] services has grown over time with the introduction of new technologies and services in libraries" (p. 228), emphasizing the central role that reference services have in DLs, and go an to discuss both free and fee-based services, and those housed as part of libraries as well as commercial services. The chapter an social issues examines the digital divide and also gives examples of institutions working to undo the divide: "Blackwells is making all 600 of its journals freely available to institutions within the Russian Federation" (p. 252). Key points in cost-models of electronic publishing and intellectual property rights are also discussed. Chowdhury and Chowdhury mention that "there is no legal deposit law to force the creators of digital information to submit a copy of every work to one or more designated institutions" for preservation (p. 265).

Abstract

This book provides a theoretical and practical explanation of the latest advancements in information retrieval and their application to existing systems. It takes a system approach, discussing all aspects of an IR system. The major difference between this book and the first edition is the addition to this text of descriptions of the automated indexing of multimedia dicuments, as items in information retrieval are now considered to be a combination of text along with graphics, audio, image and video data types. The growth of the Internet and the availability of enormous volumes of data in digital form have necessitated intense interest in techniques to assist the user in locating data

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

Rez. in: KO 31(2005), no.4, S.257-258 (B.H. Kwasnik): "According to the author, there have been many books that address the general topic of cataloging and indexing, but relatively few that focus solely an classification. This Compact and clearly written book promises to "redress the balance," and it does. From the outset the author identifies this as a textbook - one that provides theoretical underpinnings, but has as its main goal the provision of "practical advice and the promotion of practical skills" (p. vii). This is a book for the student, or for the practitioner who would like to learn about other applied bibliographic classification systems, and it considers classification as a pragmatic solution to a pragmatic problem: that of organizing materials in a collection. It is not aimed at classification researchers who study the nature of classification per se, nor at those whose primary interest is in classification as a manifestation of human cultural, social, and political values. Having said that, the author's systematic descriptions provide an exceptionally lucid and conceptually grounded description of the prevalent bibliographic classification schemes as they exist, and thus, the book Could serve as a baseline for further comparative analyses or discussions by anyone pursuing such investigations. What makes this book so appealing, even to someone who has immersed herself in this area for many years, as a practicing librarian, a teacher, and a researcher? I especially liked the conceptual framework that supported the detailed descriptions. The author defines and provides examples of the fundamental concepts of notation and the types of classifications, and then develops the notions of conveying order, brevity and simplicity, being memorable, expressiveness, flexibility and hospitality. These basic terms are then used throughout to analyze and comment an the classifications described in the various chapters: DDC, LCC, UDC, and some well-chosen examples of facetted schemes (Colon, Bliss, London Classification of Business Studies, and a hypothetical library of photographs).

In Chapter 10, "Controlled indexing languages," Professor Broughton states that a classification scheme is truly a language "since it permits communication and the exchange of information" (p. 89), a Statement with which this reviewer wholly agrees. Chapter 11, however, "Word-based approaches to retrieval," moves us to a different field altogether, offering only a narrow view of the whole world of controlled indexing languages such as thesauri, and presenting disconnected discussions of alphabetical filing, form and structure of subject headings, modern developments in alphabetical subject indexing, etc. Chapters 12 and 13 focus an the Library of Congress Subject Headings (LCSH), without even a passing reference to existing subject headings lists in other languages (French RAMEAU, German SWK, etc.). If it is not surprising to see a section on subject headings in a book on classification, the two subjects being taught together in most library schools, the location of this section in the middle of this particular book is more difficult to understand. Chapter 14 brings the reader back to classification, for a discussion of essentials of classification scheme application. The following five chapters present in turn each one of the three major and currently used bibliographic classification schemes, in order of increasing complexity and difficulty of application. The Library of Congress Classification (LCC), the easiest to use, is covered in chapters 15 and 16. The Dewey Decimal Classification (DDC) deserves only a one-chapter treatment (Chapter 17), while the functionalities of the Universal Decimal Classification (UDC), which Professor Broughton knows extremely well, are described in chapters 18 and 19. Chapter 20 is a general discussion of faceted classification, on par with the first seven chapters for its theoretical content. Chapter 21, an interesting last chapter on managing classification, addresses down-to-earth matters such as the cost of classification, the need for re-classification, advantages and disadvantages of using print versions or e-versions of classification schemes, choice of classification scheme, general versus special scheme. But although the questions are interesting, the chapter provides only a very general overview of what appropriate answers might be. To facilitate reading and learning, summaries are strategically located at various places in the text, and always before switching to a related subject. Professor Broughton's choice of examples is always interesting, and sometimes even entertaining (see for example "Inside out: A brief history of underwear" (p. 71)). With many examples, however, and particularly those that appear in the five chapters an classification scheme applications, the novice reader would have benefited from more detailed explanations. On page 221, for example, "The history and social influence of the potato" results in this analysis of concepts: Potato - Sociology, and in the UDC class number: 635.21:316. What happened to the "history" aspect? Some examples are not very convincing: in Animals RT Reproduction and Art RT Reproduction (p. 102), the associative relationship is not appropriate as it is used to distinguish homographs and would do nothing to help either the indexer or the user at the retrieval stage.

Content

"The contents of the book cover: This book is intended as an introduction to the Dewey Decimal Classification, edition 22. It is not a substitute for it, and I assume that you have it, all four volumes of it, by you while reading the book. I have deliberately included only a short section an WebDewey. This is partly because WebDewey is likely to change more frequently than the printed version, but also because this book is intended to help you use the scheme regardless of the manifestation in which it appears. If you have a subscription to WebDewey and not the printed volumes you may be able to manage with that, but you may then find my references to volumes and page numbers baffling. All the examples and exercises are real; what is not real is the idea that you can classify something without seeing more than the title. However, there is nothing that I can do about this, and I have therefore tried to choose examples whose titles adequately express their subject-matter. Sometimes when you look at the 'answers' you may feel that you have been cheated, but I hope that this will be seldom. Two people deserve special thanks. My colleague Vanda Broughton has read drafts of the book and made many suggestions. Ross Trotter, chair of the CILIP Dewey Decimal Classification Committee, who knows more about Dewey than anyone in Britain today, has commented extensively an it and as far as possible has saved me from error, as well as suggesting many improvements. What errors remain are due to me alone. Thanks are also owed to OCLC Online Computer Library Center, for permission to reproduce some specimen pages of DDC 22. Excerpts from the Dewey Decimal Classification are taken from the Dewey Decimal Classification and Relative Index, Edition 22 which is Copyright 2003 OCLC Online Computer Library Center, Inc.

Rez. in: XML Magazin und Web Services 2003, H.1, S.14 (S. Meyen): "Seit dem 22. Februar 1999 ist das Resource Description Framework (RDF) als W3C-Empfehlung verfügbar. Doch was steckt hinter diesem Standard, der das Zeitalter des Semantischen Webs einläuten soll? Was RDF bedeutet, wozu man es einsetzt, welche Vorteile es gegenüber XML hat und wie man RDF anwendet, soll in diesem Artikel erläutert werden. Schlägt man das Buch auf und beginnt, im EinleitungsKapitel zu schmökern, fällt sogleich ins Auge, dass der Leser nicht mit Lektionen im Stile von "bei XML sind die spitzen Klammern ganz wichtig" belehrt wird, obgleich es sich um ein Buch für Anfänger handelt. Im Gegenteil: Es geht gleich zur Sache und eine gesunde Mischung an Vorkenntnissen wird vorausgesetzt. Wer sich heute für XML interessiert, der hat ja mit 99-prozentiger Wahrscheinlichkeit schon seine einschlägigen Erfahrungen mit HTML und dem Web gemacht und ist kein Newbie in dem Reich der spitzen Klammern und der (einigermaßen) wohlformatierten Dokumente. Und hier liegt eine deutliche Stärke des Werkes Helmut Vonhoegens, der seinen Einsteiger-Leser recht gut einzuschätzen weiß und ihn daher praxisnah und verständlich ans Thema heranführt. Das dritte Kapitel beschäftigt sich mit der Document Type Definition (DTD) und beschreibt deren Einsatzziele und Verwendungsweisen. Doch betont der Autor hier unablässig die Begrenztheit dieses Ansatzes, welche den Ruf nach einem neuen Konzept deutlich macht: XML Schema, welches er im folgenden Kapitel darstellt. Ein recht ausführliches Kapitel widmet sich dann dem relativ aktuellen XML Schema-Konzept und erläutert dessen Vorzüge gegenüber der DTD (Modellierung komplexer Datenstrukturen, Unterstützung zahlreicher Datentypen, Zeichenbegrenzungen u.v.m.). XML Schema legt, so erfährt der Leser, wie die alte DTD, das Vokabular und die zulässige Grammatik eines XML-Dokuments fest, ist aber seinerseits ebenfalls ein XML-Dokument und kann (bzw. sollte) wie jedes andere XML auf Wohlgeformtheit überprüft werden. Weitere Kapitel behandeln die Navigations-Standards XPath, XLink und XPointer, Transformationen mit XSLT und XSL und natürlich die XML-Programmierschnittstellen DOM und SAX. Dabei kommen verschiedene Implementierungen zum Einsatz und erfreulicherweise werden Microsoft-Ansätze auf der einen und Java/Apache-Projekte auf der anderen Seite in ungefähr vergleichbarem Umfang vorgestellt. Im letzten Kapitel schließlich behandelt Vonhoegen die obligatorischen Web Services ("Webdienste") als Anwendungsfall von XML und demonstriert ein kleines C#- und ASP-basiertes Beispiel (das Java-Äquivalent mit Apache Axis fehlt leider). "Einstieg in XML" präsentiert seinen Stoff in klar verständlicher Form und versteht es, seine Leser auf einem guten Niveau "abzuholen". Es bietet einen guten Überblick über die Grundlagen von XML und kann - zumindest derzeit noch - mit recht hoher Aktualität aufwarten."

Abstract

Indexing is an activity which often goes unnoticed and can be taken for granted by reades. Indexing.- The Manual of Good Practice covers all aspects of whole document indexing of books, serial publications, images and sound materials. The book gives the purpose and principles of indexing, and covers areas such as managing the work, technology and other subject specialisms. The Manual takes the reader through the basic principles of indexing an to expert approaches, and therefore has a broad appeal for both indexers and prospective indexers whether they work freelance or in-house.
