    Rez. in: KO 36(2009) no.1, S.62-63 (K. La Barre): "This special issue of Axiomathes presents an ambitious dual agenda. It attempts to highlight aspects of facet analysis (as used in LIS) that are shared by cognate approaches in philosophy, psychology, linguistics and computer science. Secondarily, the issue aims to attract others to the study and use of facet analysis. The authors represent a blend of lifetime involvement with facet analysis, such as Vickery, Broughton, Beghtol, and Dahlberg; those with well developed research agendas such as Tudhope, and Priss; and relative newcomers such as Gnoli, Cheti and Paradisi, and Slavic. Omissions are inescapable, but a more balanced issue would have resulted from inclusion of at least one researcher from the Indian school of facet theory. Another valuable addition might have been a reaction to the issue by one of the chief critics of facet analysis. Potentially useful, but absent, is a comprehensive bibliography of resources for those wishing to engage in further study, that now lie scattered throughout the issue. Several of the papers assume relative familiarity with facet analytical concepts and definitions, some of which are contested even within LIS. Gnoli's introduction (p. 127-130) traces the trajectory, extensions and new developments of this analytico- synthetic approach to subject access, while providing a laundry list of cognate approaches that are similar to facet analysis. This brief essay and the article by Priss (p. 243-255) directly addresses this first part of Gnoli's agenda. Priss provides detailed discussion of facet-like structures in computer science (p. 245- 246), and outlines the similarity between Formal Concept Analysis and facets. This comparison is equally fruitful for researchers in computer science and library and information science. By bridging into a discussion of visualization challenges for facet display, further research is also invited. Many of the remaining papers comprehensively detail the intellectual heritage of facet analysis (Beghtol; Broughton, p. 195-198; Dahlberg; Tudhope and Binding, p. 213-215; Vickery). Beghtol's (p. 131-144) examination of the origins of facet theory through the lens of the textbooks written by Ranganathan's mentor W.C.B. Sayers (1881-1960), Manual of Classification (1926, 1944, 1955) and a textbook written by Mills A Modern Outline of Classification (1964), serves to reveal the deep intellectual heritage of the changes in classification theory over time, as well as Ranganathan's own influence on and debt to Sayers.
    Several of the papers are clearly written as primers and neatly address the second agenda item: attracting others to the study and use of facet analysis. The most valuable papers are written in clear, approachable language. Vickery's paper (p. 145-160) is a clarion call for faceted classification and facet analysis. The heart of the paper is a primer for central concepts and techniques. Vickery explains the value of using faceted classification in document retrieval. Also provided are potential solutions to thorny interface and display issues with facets. Vickery looks to complementary themes in knowledge organization, such as thesauri and ontologies as potential areas for extending the facet concept. Broughton (p. 193-210) describes a rigorous approach to the application of facet analysis in the creation of a compatible thesaurus from the schedules of the 2nd edition of the Bliss Classification (BC2). This discussion of exemplary faceted thesauri, recent standards work, and difficulties encountered in the project will provide valuable guidance for future research in this area. Slavic (p. 257-271) provides a challenge to make faceted classification come 'alive' through promoting the use of machine-readable formats for use and exchange in applications such as Topic Maps and SKOS (Simple Knowledge Organization Systems), and as supported by the standard BS8723 (2005) Structured Vocabulary for Information Retrieval. She also urges designers of faceted classifications to get involved in standards work. Cheti and Paradisi (p. 223-241) outline a basic approach to converting an existing subject indexing tool, the Nuovo Soggetario, into a faceted thesaurus through the use of facet analysis. This discussion, well grounded in the canonical literature, may well serve as a primer for future efforts. Also useful for those who wish to construct faceted thesauri is the article by Tudhope and Binding (p. 211-222). This contains an outline of basic elements to be found in exemplar faceted thesauri, and a discussion of project FACET (Faceted Access to Cultural heritage Terminology) with algorithmically-based semantic query expansion in a dataset composed of items from the National Museum of Science and Industry indexed with AAT (Art and Architecture Thesaurus). This paper looks to the future hybridization of ontologies and facets through standards developments such as SKOS because of the "lightweight semantics" inherent in facets.
    Two of the papers revisit the interaction of facets with the theory of integrative levels, which posits that the organization of the natural world reflects increasingly interdependent complexity. This approach was tested as a basis for the creation of faceted classifications in the 1960s. These contemporary treatments of integrative levels are not discipline-driven as were the early approaches, but instead are ontological and phenomenological in focus. Dahlberg (p. 161-172) outlines the creation of the ICC (Information Coding System) and the application of the Systematifier in the generation of facets and the creation of a fully faceted classification. Gnoli (p. 177-192) proposes the use of fundamental categories as a way to redefine facets and fundamental categories in "more universal and level-independent ways" (p. 192). Given that Axiomathes has a stated focus on "contemporary issues in cognition and ontology" and the following thesis: "that real advances in contemporary science may depend upon a consideration of the origins and intellectual history of ideas at the forefront of current research," this venue seems well suited for the implementation of the stated agenda, to illustrate complementary approaches and to stimulate research. As situated, this special issue may well serve as a bridge to a more interdisciplinary dialogue about facet analysis than has previously been the case."

    Abstract
    While taxonomies are being increasingly discussed in published and grey literature, the term taxonomy still seems to be stated quite loosely and obscurely. This paper aims at explaining and clarifying the concept of taxonomy in the context of information organization. To this end, the salient features of taxonomies are identified and their scope, nature, and role are further elaborated based on an extensive literature review. In the meantime, the connection and distinctions between taxonomies and classification schemes and thesauri are also identified, and the rationale that taxonomies are chosen as a viable knowledge organization system used in organization-wide websites to support browsing and aid navigation is clarified.

    Content
    Perception is a crucial element in the viability of any knowledge organization system because it acts as a filter that provides contextual information about phenomena, including potential categorical membership. Perception is moderated culturally, but "social" systems exercise little or no cultural conformity. "Every day classification" is rife throughout human experience; but classification arises as a system of formal constraints that embody cultural assumptions about the categories that are the products of human cognition. Noesis is a perceptual component of Husserl's phenomenological approach to human experience. How we perceive a thing is filtered by our experiential feelings about it. The purpose of this research is to increase understanding of the role of cognition in every day classification by developing a fuller profile of perception. Photographs of mailboxes (a mundane, every-day example) from different locales are compared to demonstrate the noetic process. Tag clouds are analyzed to demonstrate the kinds of perceptual differences that suggest different user perceptions among those contributing tags.

    Abstract
    This paper describes the Postulations Based Approach to Facet Classification as articulated by S. R. Ranganathan for knowledge classification and for the design of a facet scheme of library classification, and the Entity-Relationship Data Modelling and Analysis Approach set by Peter Pin-Sen Chen; both further modified by other experts. Efforts have been made to show the parallelism between the two approaches. It points out that, both the theoretical approaches are concerned with the organisation of knowledge or information, and apply almost similar theoretical principles, concepts, and techniques for the design and development of a framework for the organisation of knowledge, information, or data, in their respective domains. It states that both the approaches are complementary and supplementary to each other. The paper also argues that Ranganathan's postulations based approach or analytico-synthetic approach to knowledge classification can be applied for developing efficient data retrieval systems in addition to the data analysis and modelling domain.

    Abstract
    Several authors remark that categories used in languages, including indexing ones, are affected by cultural biases, and do not reflect reality in an objective way. Hence knowledge organization would essentially be determined by pragmatic factors. However, human categories are connected with the structure of reality through biological bonds, and this allows for a naturalistic approach too. Naturalism has been adopted by Farradane in proposing relational categories, and by Dahlberg and the CRG in applying the theory of integrative levels to general classification schemes. The latter is especially relevant for possible developments in making the structure of schemes independent from disciplines, and in applying it to digital information retrieval.

    Abstract
    Prior to the OPAC many institutions devised classifications to suit their special needs. Others expanded or altered general schemes to accommodate specific approaches. A driving force in the creation of these classifications was the Classification Research Group, celebrating its golden jubilee in 2002, whose work created a framework and body of principles that remain valid for the retrieval needs of today. The paper highlights some of these special schemes and highlights the fundamental principles which remain valid. 1. Introduction The distinction between a general and a special classification scheme is made frequently in the textbooks, but is one that it is sometimes difficult to draw. The Library of Congress classification could be described as the special classification par excellence. Normally, however, a special classification is taken to be one that is restricted to a specific subject, and quite often used in one specific context only, either a library or a bibliographic listing or for a specific purpose such as a search engine and it is in this sense that I propose to examine some of these schemes. Today, there is a widespread preference for searching an words as a supplement to the use of a standard system, usually the Dewey Decimal Classification (DDC). This is enhanced by the ability to search documents full-text in a computerized environment, a situation that did not exist 20 or 30 years ago. Today's situation is a great improvement in many ways, but it does depend upon the words used by the author and the searcher corresponding, and often presupposes the use of English. In libraries, the use of co-operative services and precatalogued records already provided with classification data has also spelt the demise of the special scheme. In many instances, the survival of a special classification depends upon its creaior and, with the passage of time, this becomes inevitably more precarious.

    Abstract
    Special classifications have been somewhat neglected in KO compared to general classifications. The methodology of constructing special classifications is important, however, also for the methodology of constructing general classification schemes. The methodology of constructing special classifications can be regarded as one among about a dozen approaches to domain analysis. The methodology of (special) classification in LIS has been dominated by the rationalistic facet-analytic tradition, which, however, neglects the question of the empirical basis of classification. The empirical basis is much better grasped by, for example, bibliometric methods. Even the combination of rational and empirical methods is insufficient. This presentation will provide evidence for the necessity of historical and pragmatic methods for the methodology of classification and will point to the necessity of analyzing "paradigms". The presentation covers the methods of constructing classifications from Ranganathan to the design of ontologies in computer science and further to the recent "paradigm shift" in classification research. 1. Introduction Classification of a subject field is one among about eleven approaches to analyzing a domain that are specific for information science and in my opinion define the special competencies of information specialists (Hjoerland, 2002a). Classification and knowledge organization are commonly regarded as core qualifications of librarians and information specialists. Seen from this perspective one expects a firm methodological basis for the field. This paper tries to explore the state-of-the-art conceming the methodology of classification. 2. Classification: Science or non-science? As it is part of the curriculum at universities and subject in scientific journals and conferences like ISKO, orte expects classification/knowledge organization to be a scientific or scholarly activity and a scientific field. However, very often when information specialists classify or index documents and when they revise classification system, the methods seem to be rather ad hoc. Research libraries or scientific databases may employ people with adequate subject knowledge. When information scientists construct or evaluate systems, they very often elicit the knowledge from "experts" (Hjorland, 2002b, p. 260). Mostly no specific arguments are provided for the specific decisions in these processes.

    Abstract
    Purpose - This paper aims to respond to the 2005 paper by Hjørland and Nissen Pedersen by suggesting that an exhaustive and universal classification of the phenomena that scholars study, and the methods and theories they apply, is feasible. It seeks to argue that such a classification is critical for interdisciplinary scholarship. Design/methodology/approach - The paper presents a literature-based conceptual analysis, taking Hjørland and Nissen Pedersen as its starting point. Hjørland and Nissen Pedersen had identified several difficulties that would be encountered in developing such a classification; the paper suggests how each of these can be overcome. It also urges a deductive approach as complementary to the inductive approach recommended by Hjørland and Nissen Pedersen. Findings - The paper finds that an exhaustive and universal classification of scholarly documents in terms of (at least) the phenomena that scholars study, and the theories and methods they apply, appears to be both possible and desirable. Practical implications - The paper suggests how such a project can be begun. In particular it stresses the importance of classifying documents in terms of causal links between phenomena. Originality/value - The paper links the information science, interdisciplinary, and study of science literatures, and suggests that the types of classification outlined above would be of great value to scientists/scholars, and that they are possible.

    Abstract
    One major aspect of T.D. Wilson's research has been his insistence on situating the investigation of information behaviour within the context of its occurrence - within the everyday world of work. The significance of this approach is reviewed in light of the notion of embodied cognition that characterises the evolving theoretical episteme in cognitive science research. Embodied cognition employs complex external props such as stigmergic structures and cognitive scaffoldings to reduce the cognitive burden on the individual and to augment human problem-solving activities. The cognitive function of the classification scheme is described as exemplifying both stigmergic structures and cognitive scaffoldings. Two different but complementary approaches to the investigation of situated cognition are presented: cognition-as-scaffolding and cognition-as-infrastructure. Classification-as-scaffolding views the classification scheme as a knowledge storage device supporting and promoting cognitive economy. Classification-as-infrastructure views the classification system as a social convention that, when integrated with technological structures and organisational practices, supports knowledge management work. Both approaches are shown to build upon and extend Wilson's contention that research is most productive when it attends to the social and organisational contexts of cognitive activity by focusing on the everyday world of work.

    Abstract
    This paper looks at the problems raised by maintaining an Area Table in a general scheme of classification. It examines the tools available to assist in producing a standardized listing and demonstrates how recent developments in the Universal Decimal Classification enable users to have a retrieval tool suitable for use in a networked environment which acts as both a gazetteer and a classification.

    Abstract
    Purpose - Potential and benefits of classification schemes and thesauri in building organizational taxonomies cannot be fully utilized by organizations. Empirical data of building an organizational taxonomy by the top-down approach of using classification schemes and thesauri appear to be lacking. The paper seeks to make a contribution in this regard. Design/methodology/approach - A case study of building an organizational taxonomy was conducted in the information studies domain for the Division of Information Studies at Nanyang Technology University, Singapore. The taxonomy was built by using the Dewey Decimal Classification, the Information Science Taxonomy, two information systems taxonomies, and three thesauri (ASIS&T, LISA, and ERIC). Findings - Classification schemes and thesauri were found to be helpful in creating the structure and categories related to the subject facet of the taxonomy, but organizational community sources had to be consulted and several methods had to be employed. The organizational activities and stakeholders' needs had to be identified to determine the objectives, facets, and the subject coverage of the taxonomy. Main categories were determined by identifying the stakeholders' interests and consulting organizational community sources and domain taxonomies. Category terms were selected from terminologies of classification schemes, domain taxonomies, and thesauri against the stakeholders' interests. Hierarchical structures of the main categories were constructed in line with the stakeholders' perspectives and the navigational role taking advantage of structures/term relationships from classification schemes and thesauri. Categories were determined in line with the concepts and the hierarchical levels. Format of categories were uniformed according to a commonly used standard. The consistency principle was employed to make the taxonomy structure and categories neater. Validation of the draft taxonomy through consultations with the stakeholders further refined the taxonomy. Originality/value - No similar study could be traced in the literature. The steps and methods used in the taxonomy development, and the information studies taxonomy itself, will be helpful for library and information schools and other similar organizations in their effort to develop taxonomies for organizing content and aiding navigation on organizational sites.

    Abstract
    The question of whether biologists should continue to use the Linnaean hierarchy has been a hotly debated issue. Ereshefsky argues that biologists should abandon the Linnaean system and adopt an alternative that is in line with evolutionary theory. He then makes specific recommendations for a post-Linnaean method of classification.

The author is a professor of philosophy at the University of Calgary, Canada. He has an impressive list of contributions, mostly addressing issues in biological taxonomy such as units of evolution, natural kinds and the species concept. The book is a scholarly criticism of the famous classification system developed by the Swedish botanist Carl Linnaeus (1707-1778). This system consists of both a set of rules for the naming of living organisms (biological nomenclature) and principles of classification. Linné's system has been used and adapted by biologists over a period of almost 250 years. Under the current system of codes, it is now applied to more than two million species of organisms. Inherent in the Linnaean system is the indication of hierarchic relationships. The Linnaean system has been justified primarily on the basis of stability. Although it has been criticized and alternatives have been suggested, it still has its advocates (e.g., Schuh, 2003). One of the alternatives being developed is The International Code of Phylogenetic Nomenclature, known as the PhyloCode for short, a system that radically alters the current nomenclatural rules. The new proposals have provoked hot debate on nomenclatural issues in biology. . . ."

    Abstract
    Classification is the essential first step in science. The study of science, as well as the practice of science, will thus benefit from a detailed classification of different types of science. In this book, science - defined broadly to include the social sciences and humanities - is first unpacked into its constituent elements: the phenomena studied, the data used, the theories employed, the methods applied, and the practices of scientists. These five elements are then classified in turn. Notably, the classifications of both theory types and methods allow the key strengths and weaknesses of different theories and methods to be readily discerned and compared. Connections across classifications are explored: should certain theories or phenomena be investigated only with certain methods? What is the proper function and form of scientific paradigms? Are certain common errors and biases in scientific practice associated with particular phenomena, data, theories, or methods? The classifications point to several ways of improving both specialized and interdisciplinary research and teaching, and especially of enhancing communication across communities of scholars. The classifications also support a superior system of document classification that would allow searches by theory and method used as well as causal links investigated.

    Despite its methodological flaws and lack of empirical foundation, the book could potentially bring new ideas to current discussions within the practices of curriculum development and knowledge management as weIl as design of information systems, an classification schemes as tools for knowledge sharing, decision-making and knowledge exploration. I hesitate to recommend the book to students, except to students at advanced levels of study, because of its biased presentation of the new ideas and its basis an secondary literature."

    Abstract
    Classification is a crucial skill for all information workers involved in organizing collections, but it is a difficult concept to grasp - and is even more difficult to put into practice. Essential Classification offers full guidance an how to go about classifying a document from scratch. This much-needed text leads the novice classifier step by step through the basics of subject cataloguing, with an emphasis an practical document analysis and classification. It deals with fundamental questions of the purpose of classification in different situations, and the needs and expectations of end users. The novice is introduced to the ways in which document content can be assessed, and how this can best be expressed for translation into the language of specific indexing and classification systems. The characteristics of the major general schemes of classification are discussed, together with their suitability for different classification needs.

    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.

    Abstract
    The periodic table is one of the most potent icons in science. It lies at the core of chemistry and embodies the most fundamental principles of the field. The one definitive text on the development of the periodic table by van Spronsen (1969), has been out of print for a considerable time. The present book provides a successor to van Spronsen, but goes further in giving an evaluation of the extent to which modern physics has, or has not, explained the periodic system. The book is written in a lively style to appeal to experts and interested lay-persons alike. The Periodic Table begins with an overview of the importance of the periodic table and of the elements and it examines the manner in which the term 'element' has been interpreted by chemists and philosophers. The book then turns to a systematic account of the early developments that led to the classification of the elements including the work of Lavoisier, Boyle and Dalton and Cannizzaro. The precursors to the periodic system, like Dobereiner and Gmelin, are discussed. In chapter 3 the discovery of the periodic system by six independent scientists is examined in detail. Two chapters are devoted to the discoveries of Mendeleev, the leading discoverer, including his predictions of new elements and his accommodation of already existing elements. Chapters 6 and 7 consider the impact of physics including the discoveries of radioactivity and isotopy and successive theories of the electron including Bohr's quantum theoretical approach. Chapter 8 discusses the response to the new physical theories by chemists such as Lewis and Bury who were able to draw on detailed chemical knowledge to correct some of the early electronic configurations published by Bohr and others. Chapter 9 provides a critical analysis of the extent to which modern quantum mechanics is, or is not, able to explain the periodic system from first principles. Finally, chapter 10 considers the way that the elements evolved following the Big Bang and in the interior of stars. The book closes with an examination of further chemical aspects including lesser known trends within the periodic system such as the knight's move relationship and secondary periodicity, as well at attempts to explain such trends.
    Footnote
    Rez. in: KO 35(2008) no.4, S.251-254 (B. Hjoerland): "The book is about the classification of chemical elements known as the periodical system. It is described as "one of the most potent icons in science [.] One sees periodic tables everywhere: in industrial labs, workshops, academic labs, and of course, lecture halls" (p. xiii). Among all taxonomies in all domains, there is probably none more respected and more useful than this one. As Scerri states (p. 25): The periodic table ranks as one of the most fruitful and unifying ideas in the whole of modern science, comparable perhaps with Darwin's theory of evolution by natural selection. Unlike such theories as Newtonian mechanics, the periodic table has not been falsified by developments in modern physics but has evolved while remaining essentially unchanged. After evolving for nearly 150 years through the work of numerous individuals, the periodic table remains at the heart of chemistry. This is mainly because it is of immense practical benefit for making predictions about all manner of chemical and physical properties of the elements and possibilities for bond formation. The periodic system provides the basic criteria for organizing knowledge about all the material stuff in the entire universe. It is thus a model that anybody with interests in knowledge organization (KO) should know. Knowledge about the history, philosophy and status of the periodic system also provides important insight for knowledge organization in general. . . . Scerri's book demonstrates how one of the most important classification systems has evolved and what kinds of conceptualizations and classification criteria are at work in it. It is probably the best book about the best classification system ever constructed. It should belong to any library supporting teaching and research in knowledge organization."

    Abstract
    Taxonomy reflects the human instinct to organize. Once limited in Western culture to certain natural sciences, in the early twenty-first century, it has expanded to many domains, practices, and uses. Domains now include almost anything of interest, but particularly those motivated by business needs. Practices and uses include description, analysis, prediction, mapping terminology, information access, representation of knowledge, and tool-building. For information science, taxonomy is a powerful tool for connecting information content with information consumers effectively and efficiently.
