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.

Rez. in: JASIST 57(2006) no.8, S.1132-1133 (H. Che): "The World Wide Web has been the main source of an important shift in the way people communicate with each other, get information, and conduct business. However, most of the current Web content is only suitable for human consumption. The main obstacle to providing better quality of service is that the meaning of Web content is not machine-accessible. The "Semantic Web" is envisioned by Tim Berners-Lee as a logical extension to the current Web that enables explicit representations of term meaning. It aims to bring the Web to its full potential via the exploration of these machine-processable metadata. To fulfill this, it pros ides some meta languages like RDF, OWL, DAML+OIL, and SHOE for expressing knowledge that has clear, unambiguous meanings. The first steps in searing the Semantic Web into the current Web are successfully underway. In the forthcoming years, these efforts still remain highly focused in the research and development community. In the next phase, the Semantic Web will respond more intelligently to user queries. The first chapter gets started with an excellent introduction to the Semantic Web vision. At first, today's Web is introduced, and problems with some current applications like search engines are also covered. Subsequently, knowledge management. business-to-consumer electronic commerce, business-to-business electronic commerce, and personal agents are used as examples to show the potential requirements for the Semantic Web. Next comes the brief description of the underpinning technologies, including metadata, ontology, logic, and agent. The differences between the Semantic Web and Artificial Intelligence are also discussed in a later subsection. In section 1.4, the famous "laser-cake" diagram is given to show a layered view of the Semantic Web. From chapter 2, the book starts addressing some of the most important technologies for constructing the Semantic Web. In chapter 2, the authors discuss XML and its related technologies such as namespaces, XPath, and XSLT. XML is a simple, very flexible text format which is often used for the exchange of a wide variety of data on the Web and elsewhere. The W3C has defined various languages on top of XML, such as RDF. Although this chapter is very well planned and written, many details are not included because of the extensiveness of the XML technologies. Many other books on XML provide more comprehensive coverage.
The next chapter introduces resource description framework (RDF) and RDF schema (RDFS). Unlike XML, RDF provides a foundation for expressing the semantics of dada: it is a standard dada model for machine-processable semantics. Resource description framework schema offers a number of modeling primitives for organizing RDF vocabularies in typed hierarchies. In addition to RDF and RDFS, a query language for RDF, i.e. RQL. is introduced. This chapter and the next chapter are two of the most important chapters in the book. Chapter 4 presents another language called Web Ontology Language (OWL). Because RDFS is quite primitive as a modeling language for the Web, more powerful languages are needed. A richer language. DAML+OIL, is thus proposed as a joint endeavor of the United States and Europe. OWL takes DAML+OIL as the starting point, and aims to be the standardized and broadly accepted ontology language. At the beginning of the chapter, the nontrivial relation with RDF/RDFS is discussed. Then the authors describe the various language elements of OWL in some detail. Moreover, Appendix A contains an abstract OWL syntax. which compresses OWL and makes OWL much easier to read. Chapter 5 covers both monotonic and nonmonotonic rules. Whereas the previous chapter's mainly concentrate on specializations of knowledge representation, this chapter depicts the foundation of knowledge representation and inference. Two examples are also givwn to explain monotonic and non-monotonic rules, respectively. "To get the most out of the chapter. readers had better gain a thorough understanding of predicate logic first. Chapter 6 presents several realistic application scenarios to which the Semantic Web technology can be applied. including horizontal information products at Elsevier, data integration at Audi, skill finding at Swiss Life, a think tank portal at EnerSearch, e-learning. Web services, multimedia collection indexing, online procurement, raid device interoperability. These case studies give us some real feelings about the Semantic Web.
The chapter on ontology engineering describes the development of ontology-based systems for the Web using manual and semiautomatic methods. Ontology is a concept similar to taxonomy. As stated in the introduction, ontology engineering deals with some of the methodological issues that arise when building ontologies, in particular, con-structing ontologies manually, reusing existing ontologies. and using semiautomatic methods. A medium-scale project is included at the end of the chapter. Overall the book is a nice introduction to the key components of the Semantic Web. The reading is quite pleasant, in part due to the concise layout that allows just enough content per page to facilitate readers' comprehension. Furthermore, the book provides a large number of examples, code snippets, exercises, and annotated online materials. Thus, it is very suitable for use as a textbook for undergraduates and low-grade graduates, as the authors say in the preface. However, I believe that not only students but also professionals in both academia and iudustry will benefit from the book. The authors also built an accompanying Web site for the book at http://www.semanticwebprimer.org. On the main page, there are eight tabs for each of the eight chapters. For each tabm the following sections are included: overview, example, presentations, problems and quizzes, errata, and links. These contents will greatly facilitate readers: for example, readers can open the listed links to further their readings. The vacancy of the errata sections also proves the quality of the book."

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).
Chapter 13 an DL evaluation merges criteria from traditional library evaluation with criteria from user interface design and information retrieval. Quantitative, macro-evaluation techniques are emphasized, and again, some DL evaluation projects and reports are illustrated. A very brief chapter an the role of librarians in the DL follows, emphasizing that traditional reference skills are paramount to the success of the digital librarian, but that he should also be savvy in Web page and user interface design. A final chapter an research trends in digital libraries seems a bit incoherent. It mentions many of the previous chapters' topics, and would possibly be better organized if written as summary sections and distributed among the other chapters. The book's breadth is quite expansive, touching an both fundamental and advanced topics necessary to a well-rounded DL education. As the book is thoroughly referenced to DL and DL-related research projects, it serves as a useful starting point for those interested in more in depth learning. However, this breadth is also a weakness. In my opinion, the sheer number of research projects and papers surveyed leaves the authors little space to critique and summarize key issues. Many of the case studies are presented as itemized lists and not used to exemplify specific points. I feel that an introductory text should exercise some editorial and evaluative rights to create structure and organization for the uninitiated. Case studies should be carefully Chosen to exemplify the specific issues and differences and strengths highlighted. It is lamentable that in many of the descriptions of research projects, the authors tend to give more historical and funding Background than is necessary and miss out an giving a synthesis of the pertinent details.
Another weakness of the book is its favoritism towards the authors' own works. To a large extent, this bias is natural as the authors know their own works best. However, in an introductory text, it is critical to reference the most appropriate source and give a balanced view of the field. In this respect, 1 feel the book could be more objective in its selection of references and research projects. Introduction to Digital Libraries is definitely a book written for a purpose. LIS undergraduates and "practicing professionals who need to know about recent developments in the field of digital libraries" (p. xiv) will find this book a fine introduction, as it is clearly written and accessible to laymen, giving explanations without delving into terminology and math. As it surveys a large number of projects, it is also an ideal starting point for students to pick and investigate particular DL research projects. However, graduate LIS students who already have a solid understanding of library fundamentals as well as Computer science students may find this volume lacking in details. Alternative texts such as Lesk (1999) and Arms (2000) are possibly more suitable for those who need to investigate topics in depth. For the experienced practitioner or researcher delving into the DL field for the first time, the recent 2002 ARIST chapter by Fox and Urs may also be a suitable alternative. In their introduction, the authors ask, "What are digital libraries? How do they differ from online databases and search services? Will they replace print libraries? What impact will they have an people and the society?" (p. 3). To answer these questions, Chowdhury and Chowdhury offer a multitude of case studies to let the audience draw their own conclusions. To this end, it is my opinion that Introduction to Digital Libraries serves a useful purpose as a supplemental text in the digital library Curriculum but misses the mark of being an authoritative textbook."

Oberhauser): " ...Allen kritischen Anmerkungen zum Trotz: Im Vergleich mit der letzten Auflage schneidet diese fünfte Ausgabe erfreulich positiv ab (nur Nörgler würden sagen, dass dies nicht schwergefallen ist). Natürlich könnte darüber reflektiert werden, ob es heute noch möglich ist, das Gesamtgebiet der Informationswissenschaft und -praxis in einem Handbuch erschöpfend darzustellen; die Zeiten, in denen man Wissenschaftsdisziplinen auf diese Weise repräsentierte und legitimierte, sind eigentlich vorüber. Andererseits fehlen, gerade im deutschen Sprachraum, weitgehend gute und aktuelle Darstellungen zu den hier präsentierten Teilbereichen. Als Einstieg in die Informationswissenschaft und -praxis ist das vorliegende Handbuch daher allemal wichtig. Auch für gestandene Praktiker bietet es viele interessante und neue Themen. Der Preis für die broschierte Ausgabe ist vielleicht nicht gerade wohlfeil, aber nach heutigen Massstäben dem Umfang angemessen. Grössere Bibliotheken und bibliothekarische bzw. informationswissenschaftliche Ausbildungseinrichtungen, für die auch diese Ausgabe unverzichtbar ist, werden dagegen wohl eher zur teureren gebundenen Variante greifen."

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.
