"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.

"The title says it all. The book contains the essentials for a fundamental understanding of the complex world of the Dewey Decimal Classification. It is clearly written and captures the essence in a concise and readable style. Is it a coincidence that the mysteries of the Dewey Decimal System are revealed in ten easy chapters? The typography and layout are clear and easy to read and the perfect binding withstood heavy use. The exercises and answers are invaluable in illustrating the points of the several chapters. The book is well structured. Chapter 1 provides an "Introduction and background" to classification in general and Dewey in particular. Chapter 2 describes the "Outline of the scheme" and the conventions in the schedules and tables. Chapter 3 covers "Simple subjects" and introduces the first of the exercises. Chapters 4 and 5 describe "Number-building" with "standard subdivisions" in the former and "other methods" in the latter. Chapter 6 provides an excellent description of "Preference order" and Chapter 7 deals with "Exceptions and options." Chapter 8 "Special subjects," while no means exhaustive, gives a thorough analysis of problems with particular parts of the schedules from "100 Philosophy" to "910 Geography" with a particular discussion of "'Persons treatment"' and "Optional treatment of biography." Chapter 9 treats "Compound subjects." Chapter 10 briefly introduces WebDewey and provides the URL for the Web Dewey User Guide http://www.oclc.org/support/documentation/dewey/ webdewey_userguide/; the section for exercises says: "You are welcome to try using WebDewey an the exercises in any of the preceding chapters." Chapters 6 and 7 are invaluable at clarifying the options and bases for choice when a work is multifaceted or is susceptible of classification under different Dewey Codes. The recommendation "... not to adopt options, but use the scheme as instructed" (p. 71) is clearly sound. As is, "What is vital, of course, is that you keep a record of the decisions you make and to stick to them. Any option Chosen must be used consistently, and not the whim of the individual classifier" (p. 71). The book was first published in the UK and the British overtones, which may seem quite charming to a Canadian, may be more difficult for readers from the United States. The correction of Dewey's spelling of Labor to Labo [u] r (p. 54) elicited a smile for the championing of lost causes and some relief that we do not have to cope with 'simplified speling.' The down-to-earth opinions of the author, which usually agree with those of the reviewer, add savour to the text and enliven what might otherwise have been a tedious text indeed. However, in the case of (p. 82):
Dewey requires that you classify bilingual dictionaries that go only one way with the language in which the entries are written, which means that an English-French dictionary has to go with English, not French. This is very unhelpful and probably not widely observed in English-speaking libraries ... one may wonder (the Norman conquest not withstanding) why Bowman feels that it is more useful to class the book in the language of the definition rather than that of the entry words - Dewey's requirement to class a dictionary of French words with English definitions with French language dictionaries seems quite reasonable. In the example of Anglo-French relations before the second World War (p. 42) the principle of adding two notations from Table 2 is succinctly illustrated but there is no discussion of why the notation is -41044 rather than -44041. Is it because the title is 'Anglo'-'French', or because -41 precedes -44, or because it is assumed that the book is being catalogued for an English library that wished to keep all Anglo relations together? The bibliography lists five classic works and the School Library Association (UK) website. The index provides additional assistance in locating topics; however it is not clear whether it is intended to be a relative index with terms in direct order or nouns with subdivisions. There are a few Cross-references and some double posting. The instruction ") ( means 'compared with"' (p. 147) seems particularly twee since the three occasions in the index could easily have included the text "compared with;" the saving of space is not worth the potential confusion. There is no entry for "displaced standard subdivisions" one must look under "standard subdivisions" with the subdivision "displaced." There is no entry for "approximating the whole," although "standing room," "class here notes" and "including notes" are listed. Both "rule of zero" and "zero" with the subdivision "rule of" are included. The "rule of zero" is really all you need to know about Dewey (p. 122): Something which can be useful if you are really stuck is to consider the possibilities one digit at a time, and never put 0 if you can put something more specific. Be as specific as possible, but if you can't say something good, say nothing. This slim volume clearly follows this advice."

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: KO 32(2005) no.1, S.47-49 (M. Hudon): "Vanda Broughton's Essential Classification is the most recent addition to a very small set of classification textbooks published over the past few years. The book's 21 chapters are based very closely an the cataloguing and classification module at the School of Library, Archive, and Information studies at University College, London. The author's main objective is clear: this is "first and foremost a book about how to classify. The emphasis throughout is an the activity of classification rather than the theory, the practical problems of the organization of collections, and the needs of the users" (p. 1). This is not a theoretical work, but a basic course in classification and classification scheme application. For this reviewer, who also teaches "Classification 101," this is also a fascinating peek into how a colleague organizes content and structures her course. "Classification is everywhere" (p. 1): the first sentence of this book is also one of the first statements in my own course, and Professor Broughton's metaphors - the supermarket, canned peas, flowers, etc. - are those that are used by our colleagues around the world. The combination of tone, writing style and content display are reader-friendly; they are in fact what make this book remarkable and what distinguishes it from more "formal" textbooks, such as The Organization of Information, the superb text written and recently updated (2004) by Professor Arlene Taylor (2nd ed. Westport, Conn.: Libraries Unlimited, 2004). Reading Essential Classification, at times, feels like being in a classroom, facing a teacher who assures you that "you don't need to worry about this at this stage" (p. 104), and reassures you that, although you now speed a long time looking for things, "you will soon speed up when you get to know the scheme better" (p. 137). This teacher uses redundancy in a productive fashion, and she is not afraid to express her own opinions ("I think that if these concepts are helpful they may be used" (p. 245); "It's annoying that LCC doesn't provide clearer instructions, but if you keep your head and take them one step at a time [i.e. the tables] they're fairly straightforward" (p. 174)). Chapters 1 to 7 present the essential theoretical concepts relating to knowledge organization and to bibliographic classification. The author is adept at making and explaining distinctions: known-item retrieval versus subject retrieval, personal versus public/shared/official classification systems, scientific versus folk classification systems, object versus aspect classification systems, semantic versus syntactic relationships, and so on. Chapters 8 and 9 discuss the practice of classification, through content analysis and subject description. A short discussion of difficult subjects, namely the treatment of unique concepts (persons, places, etc.) as subjects seems a little advanced for a beginners' class.
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.
Essential Classification is also an exercise book. Indeed, it contains a number of practical exercises and activities in every chapter, along with suggested answers. Unfortunately, the answers are too often provided without the justifications and explanations that students would no doubt demand. The author has taken great care to explain all technical terms in her text, but formal definitions are also gathered in an extensive 172-term Glossary; appropriately, these terms appear in bold type the first time they are used in the text. A short, very short, annotated bibliography of standard classification textbooks and of manuals for the use of major classification schemes is provided. A detailed 11-page index completes the set of learning aids which will be useful to an audience of students in their effort to grasp the basic concepts of the theory and the practice of document classification in a traditional environment. Essential Classification is a fine textbook. However, this reviewer deplores the fact that it presents only a very "traditional" view of classification, without much reference to newer environments such as the Internet where classification also manifests itself in various forms. In Essential Classification, books are always used as examples, and we have to take the author's word that traditional classification practices and tools can also be applied to other types of documents and elsewhere than in the traditional library. Vanda Broughton writes, for example, that "Subject headings can't be used for physical arrangement" (p. 101), but this is not entirely true. Subject headings can be used for physical arrangement of vertical files, for example, with each folder bearing a simple or complex heading which is then used for internal organization. And if it is true that subject headings cannot be reproduced an the spine of [physical] books (p. 93), the situation is certainly different an the World Wide Web where subject headings as metadata can be most useful in ordering a collection of hot links. The emphasis is also an the traditional paperbased, rather than an the electronic version of classification schemes, with excellent justifications of course. The reality is, however, that supporting organizations (LC, OCLC, etc.) are now providing great quality services online, and that updates are now available only in an electronic format and not anymore on paper. E-based versions of classification schemes could be safely ignored in a theoretical text, but they have to be described and explained in a textbook published in 2005. One last comment: Professor Broughton tends to use the same term, "classification" to represent the process (as in classification is grouping) and the tool (as in constructing a classification, using a classification, etc.). Even in the Glossary where classification is first well-defined as a process, and classification scheme as "a set of classes ...", the definition of classification scheme continues: "the classification consists of a vocabulary (...) and syntax..." (p. 296-297). Such an ambiguous use of the term classification seems unfortunate and unnecessarily confusing in an otherwise very good basic textbook an categorization of concepts and subjects, document organization and subject representation."

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.
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).
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."

Rez. in: Mitt. VÖB 63(2010) H.1, S.143-147 (O. Oberhauser): " ... Kommen wir zur Kritik, die in den letzten Absätzen ansatzweise schon angeklungen ist. Das Anliegen des Buches ist, wie dem ersten Satz der Einleitung zu entnehmen ist, "to simplify the initial study of classification as used for knowledge organisation and information retrieval" (p. xi). Dies ist dem Autor in den ersten Kapiteln wohl auch gelungen. Die Einführung in die beiden Grundtypen - hier facettierte, dort hierarchische Systeme - ist verständlich und für Anfänger zweifellos gut geeignet. In den folgenden Kapiteln beginnt man sich aber zu fragen, wer eigentlich die Zielgruppe des Buches sein mag. Für Anfänger wird vieles zu schwierig sein, da gerade bei den anspruchsvolleren Aspekten der Text zu oberflächlich ist, keine didaktisch befriedigende Darstellung erfolgt und gelegentlich sogar Fachkenntnisse vorausgesetzt werden. Für Praktiker aus dem Bibliothekswesen fehlt vielfach der Bezug zur alltäglichen Realität, da z.B. Probleme der Buchaufstellung allenfalls am Rande zur Sprache kommen. Hochschullehrer, die eine Lehrveranstaltung zu Klassifikationsthemen vorbereiten müssen, werden manches an dem Buch nützlich finden, vielfach aber ob der mangelnden Detailliertheit zu anderen Unterlagen greifen. So bleibt der oder die "an Fragen der Klassifikation Interessierte" - ein undefiniertes und nicht allzu häufig anzutreffendes Wesen, das aber wahrscheinlich auch existiert und hier eine Fülle von Punkten angerissen findet, die zu einer weiteren Recherche in anderen Quellen animieren. Gut gelungen sind die zahlreichen Beispiele, selbst wenn dafür nicht immer sehr glückliche Notationssysteme gewählt wurden. Auch in sprachlicher Hinsicht ist - zumindest in den Anfangskapiteln - nichts zu bemängeln. Dass die beiden letzten Kapitel eher misslungen sind, wurde bereits oben angedeutet. In den übrigen Abschnitten merkt man dem Buch ebenfalls immer wieder an, dass es in seinen Grundzügen aus der Papier- und nicht aus der Online-Zeit stammt. Dennoch will ich nicht über Gebühr lamentieren, schon deshalb, da es gar nicht so viele brauchbare Lehrbücher zu Klassifikationsthemen gibt. Und in diese letztere Kategorie gehört Hunters Text alldieweil."

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).
The heart of the book lies in its exceptionally clear and well illustrated explanation of each of the classification schemes. These are presented comprehensively, but also in gratifying detail, down to the meaning of the various enigmatic notes and notations, such as "config" or "class elsewhere" notes, each simply explained, as if a teacher were standing over your shoulder leading you through it. Such attention at such a fine level may seem superfluous or obvious to a seasoned practitioner, but it is in dealing with such enigmatic details that we find students getting discouraged and confused. That is why I think this would be an excellent text, especially as a book to hold in one hand and the schedules themselves in the other. While the examples throughout and the practical exercises at the end of each chapter are slanted towards British topics, they are aptly Chosen and should present no problem of understanding to a student anywhere. As mentioned, this is an unabashedly practical book, focusing an classification as it has been and is presently applied in libraries for maintaining a "useful book order." It aims to develop those skills that would allow a student to learn how it is done from a procedural rather than a critical perspective. At times, though, one wishes for a bit more of a critical approach - one that would help a student puzzle through some of the ambiguities and issues that the practice of classification in an increasingly global rather than local environment entails. While there is something to be said for a strong foundation in existing practice (to understand from whence it all came), the author essentially accepts the status quo, and ventures almost timidly into any critique of the content and practice of existing classification schemes. This lack of a critical analysis manifests itself in several ways: - The content of the classification schemes as described in this book is treated as fundamentally "correct" or at least "given." This is not to say the author doesn't recognize anomalies and shortcomings, but that her approach is to work with what is there. Where there are logical flaws in the knowledge representation structures, the author takes the approach that there are always tradeoffs, and one must simply do the best one can. This is certainly true for most people working in libraries where the choice of scheme is not controlled by the classifier, and it is a wonderful skill indeed to be able to organize creatively and carefully despite imperfect systems. The approach is less convincing, however, when it is also applied to emerging or newly developed schemes, such as those proposed for organizing electronic resources. Here, the author could have been a bit braver in at least encouraging less normative approaches. - There is also a lingering notion that classification is a precise science. For example the author states (p. 13): Hospitality is the ability to accommodate new topics and concepts in their correct place in the schedules ... Perfect hospitality world mean that every new subject could be accommodated in the most appropriate place in the schedules. In practice, schemes do manage to fit new subjects in, but not necessarily in their most appropriate place. It world have been helpful to acknowledge that for many complex subjects there is no one appropriate place. The author touches an this dilemma, but in passing, and not usually when she is providing practical pointers.
- Similarly, there is very little space provided to the thorny issue of subject analysis, which is at the conceptual core of classification work of any kind. The author's recommendations are practical, and do not address the subjective nature of this activity, nor the fundamental issues of how the classification schemes are interpreted and applied in diverse contexts, especially with respect to what a work "is about." - Finally, there is very little about practical problem solving - stories from the trenches as it were. How does a classifier choose one option over another when both seem plausible, even given that he or she has done a user and task analysis? How do classifiers respond to rapid or seemingly impulsive change? How do we evaluate the products of our work? How do we know what is the "correct" solution, even if we work, as most of us do, assuming that this is an elusive goal, but we try our best anyway? The least satisfying section of the book is the last, where the author proposes some approaches to organizing electronic resources. The suggestions seem to be to more or less transpose and adapt skills and procedures from the world of organizing books an shelves to the virtual hyperlinked world of the Web. For example, the author states (p. 153-54): Precise classification of documents is perhaps not as crucial in the electronic environment as it is in the traditional library environment. A single document can be linked to and retrieved via several different categories to allow for individual needs and expertise. However, it is not good practice to overload the system with links because that will affect its use. Effort must be made to ensure that inappropriate or redundant links are not included. The point is well taken: too muck irrelevant information is not helpful. At the same time an important point concerning the electronic environment has been overlooked as well: redundancy is what relieves the user from making precise queries or knowing the "right" place for launching a search, and redundancy is what is so natural an the Web. These are small objections, however. Overall the book is a carefully crafted primer that gives the student a strong foundation an which to build further understanding. There are well-chosen and accessible references for further reading. I world recommend it to any instructor as an excellent starting place for deeper analysis in the classroom and to any student as an accompanying text to the schedules themselves."

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."
