- Abstract
- What is the difference between Piaget's constructivism and Papert's "constructionism"? Beyond the mere play on the words, I think the distinction holds, and that integrating both views can enrich our understanding of how people learn and grow. Piaget's constructivism offers a window into what children are interested in, and able to achieve, at different stages of their development. The theory describes how children's ways of doing and thinking evolve over time, and under which circumstance children are more likely to let go of-or hold onto- their currently held views. Piaget suggests that children have very good reasons not to abandon their worldviews just because someone else, be it an expert, tells them they're wrong. Papert's constructionism, in contrast, focuses more on the art of learning, or 'learning to learn', and on the significance of making things in learning. Papert is interested in how learners engage in a conversation with [their own or other people's] artifacts, and how these conversations boost self-directed learning, and ultimately facilitate the construction of new knowledge. He stresses the importance of tools, media, and context in human development. Integrating both perspectives illuminates the processes by which individuals come to make sense of their experience, gradually optimizing their interactions with the world.

- Abstract
- Moving to a fully faceted syntax would resolve three problems facing Library of Congress Subject Headings (LCSH): 1. Inconsistent syntax rules; 2. Inability to create headings that are coextensive with the topic of a work; and 3. Lack of effective displays for long lists of subdivisions under a single subject heading in OPACs and similar electronic displays. The authors advocate a fully faceted syntax using the facets of a modern faceted library classification (The Bliss Bibliographic Classification, 2d ed.). They demonstrate how this might be accomplished so as to integrate the new syntax with existing headings.

- Abstract
- LCSH are increasingly seen as 'the' English language controlled vocabulary, despite their lack of a theoretical foundation, and their evident US bias. In mapping exercises between national subject heading lists, and in exercises in digital resource organization and management, LCSH are often chosen because of the lack of any other widely accepted English language standard for subject cataloguing. It is therefore important that the basic nature of LCSH, their advantages, and their limitations, are well understood both by LIS practitioners and those in the wider information community. Information professionals who attended library school before 1995 - and many more recent library school graduates - are unlikely to have had a formal introduction to LCSH. Paraprofessionals who undertake cataloguing are similarly unlikely to have enjoyed an induction to the broad principles of LCSH. There is currently no compact guide to LCSH written from a UK viewpoint, and this eminently practical text fills that gap. It features topics including: background and history of LCSH; subject heading lists; structure and display in LCSH; form of entry; application of LCSH; document analysis; main headings; topical, geographical and free-floating sub-divisions; building compound headings; name headings; headings for literature, art, music, history and law; and, LCSH in the online environment. There is a strong emphasis throughout on worked examples and practical exercises in the application of the scheme, and a full glossary of terms is supplied. No prior knowledge or experience of subject cataloguing is assumed. This is an indispensable guide to LCSH for practitioners and students alike from a well-known and popular author.

- Abstract
- In 1986 Libraries Unlimited published Cochrane's book, Improving LCSH for Use in Online Catalogs; Exercises for Self-Help with a Selection of Background Readings. This was preceded in 1981 by an ERIC publication (ED 208 900) by Cochrane, with Monika Kirtland Bibliographic and Bibliometric Essay which documented critical views of LCSH and an analysis of vocabulary control in LCSH (parts of which were published in Cataloging & Classification Quarterly' 1(2/3) (1982), 71-94). Three features of LCSH will be re-examined to check on progress since the time of these earlier publications: notes, structure of relationships between headings in the list, and links between Library of Congress classification numbers and LCSH or other vocabularies

- Abstract
- This paper presents a study that assessed the feasibility of applying the approach of the Faceted Application of Subject Terminology (FAST), an initiative of the Online Computer Library Center (OCLC), to records in the Ulrich's Periodicals Directory.? The goal is to determine whether a simplified application of Library of Congress Subject Headings (LCSH), as illustrated by FAST, would benefit the Ulrich's system. This feasibility study found that although a few problems were encountered in the process, overall the FAST database was useful for converting Ulrich's subject headings into FAST headings.

- Abstract
- The Library of Congress Subject Headings (LCSH) has been developed over the course of more than a century, predating the semantic web by some time. Until the 1986, the only concept-toconcept relationship available was an undifferentiated "See Also" reference, which was used for both associative (RT) and hierarchical (BT/NT) connections. In that year, in preparation for the first release of the headings in machine readable MARC Authorities form, an attempt was made to automatically convert these "See Also" links into the standardized thesaural relations. Unfortunately, the rule used to determine the type of reference to generate relied on the presence of symmetric links to detect associatively related terms; "See Also" references that were only present in one of the related terms were assumed to be hierarchical. This left the process vulnerable to inconsistent use of references in the pre-conversion data, with a marked bias towards promoting relationships to hierarchical status. The Library of Congress was aware that the results of the conversion contained many inconsistencies, and intended to validate and correct the results over the course of time. Unfortunately, twenty years later, less than 40% of the converted records have been evaluated. The converted records, being the earliest encountered during the Library's cataloging activities, represent the most basic concepts within LCSH; errors in the syndetic structure for these records affect far more subordinate concepts than those nearer the periphery. Worse, a policy of patterning new headings after pre-existing ones leads to structural errors arising from the conversion process being replicated in these newer headings, perpetuating and exacerbating the errors. As the LCSH prepares for its second great conversion, from MARC to SKOS, it is critical to address these structural problems. As part of the work on converting the headings into SKOS, I have experimented with different visualizations of the tangled web of broader terms embedded in LCSH. This poster illustrates several of these renderings, shows how they can help users to judge which relationships might not be correct, and shows just exactly how Doorbells and Mammals are related.

- Abstract
- Document representations for text classification are typically based on the classical Bag-Of-Words paradigm. This approach comes with deficiencies that motivate the integration of features on a higher semantic level than single words. In this paper we propose an enhancement of the classical document representation through concepts extracted from background knowledge. Boosting is used for actual classification. Experimental evaluations on two well known text corpora support our approach through consistent improvement of the results.

- Abstract
- Some members of the library community, including the Library of Congress Working Group on the Future of Bibliographic Control, have suggested that libraries should open up their catalogs to allow users to add descriptive tags to the bibliographic data in catalog records. The web site LibraryThing currently permits its members to add such user tags to its records for books and therefore provides a useful resource to contrast with library bibliographic records. A comparison between the LibraryThing tags for a group of books and the library-supplied subject headings for the same books shows that users and catalogers approach these descriptors very differently. Because of these differences, user tags can enhance subject access to library materials, but they cannot entirely replace controlled vocabularies such as the Library of Congress subject headings.

The purpose suggested by the title is fulfilled, serving as a companion to the 19th edition of the Sears List. It is designed a a manual for beginners who will realize the importance of vocabulary control and subject analysis, and start to comprehend the structure and organization of the Sears List as well as the methods and techniques to locate, specify, and construct subject headings. The book, however, lacks a good number of examples for practice. The emphasis seems to have been put more on the theoretical than the practical aspects. Despite this criticism, I unreservedly value the authors' efforts. At the same time, I can't help but wonder if the book will have wide access as the place of publication, the cost and the availability will especially affect the users in developing countries. The User's Guide will be a valuable tool to technical services librarians, subject catalogers, students and teachers of library and information science. It is intended for college and university libraries in general, but more particularly for library schools. The authors produced a work of high quality that stands out in its category.

- Abstract
- This study is an examination of the overlap between author-assigned keywords and cataloger-assigned Library of Congress Subject Headings (LCSH) for a set of electronic theses and dissertations in Ohio State University's online catalog. The project is intended to contribute to the literature on the issue of keywords versus controlled vocabularies in the use of online catalogs and databases. Findings support previous studies' conclusions that both keywords and controlled vocabularies complement one another. Further, even in the presence of bibliographic record enhancements, such as abstracts or summaries, keywords and subject headings provided a significant number of unique terms that could affect the success of keyword searches. Implications for the maintenance of controlled vocabularies such as LCSH also are discussed in light of the patterns of matches and nonmatches found between the keywords and their corresponding subject headings.

- Abstract
- The history of the Library of Congress Subject Headings is traced, from its beginnings with the implementation of a dictionary catalog at the Library of Congress in 1898 to the present day. The author describes the most significant changes which have occurred in LCSH policies and practices during the 100-year period. Events noted near the end of the century indicate an increased willingness on the part of' the Library of Congress to involve the larger library community in the creation or revision of subject headings and other decision-making regarding the LCSH system. Finally, the author provides a summary of the other contributions to this collection of essays, a collection which celebrates the "centennial" of the world's most popular library subject heading language

- Abstract
- Library of Congress Subject Headings (LSCH), which celebrated its 100th birthday in 1998, is the largest cataloging and indexing language in the world for the indication of the topics and formats of books and similar publications. It consists of a controlled list of main headings, many with subdivisions, with a rich system of cross references. It is supported by the U.S. government, and undergoes systematic revision. In recent decades its managers have begun to confront challenges such as biased terminology, complicated syntax (how terms are put together to form headings), and effective displays in electronic media. Many suggestions have been made for its improvement, including moving to a fully faceted system.

- 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.

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."
