Abstract

That there is a "digital divide" - which falls between those who have and can afford the latest in technological tools and those who have neither in our society - is indisputable. "Virtual Inequality" redefines the issue as it explores the cascades of that divide, which involve access, skill, political participation, as well as the obvious economics. Computer and Internet access are insufficient without the skill to use the technology, and economic opportunity and political participation provide primary justification for realizing that this inequality is a public problem and not simply a matter of private misfortune. Defying those who say the divide is growing smaller, this volume, based on a national survey that includes data from over 1800 respondents in low-income communities, shows otherwise. In addition to demonstrating why disparities persist in such areas as technological abilities, the survey also shows that the digitally disadvantaged often share many of the same beliefs as their more privileged counterparts. African-Americans, for instance, are even more positive in their attitudes toward technology than whites are in many respects, contrary to conventional wisdom. The rigorous research on which the conclusions are based is presented accessibly and in an easy-to-follow manner. Not content with analysis alone, nor the untangling of the complexities of policymaking, "Virtual Inequality" views the digital divide compassionately in its human dimensions and recommends a set of practical and common-sense policy strategies. Inequality, even in a virtual form this book reminds us, is unacceptable and a situation that society is compelled to address.

Abstract

Many information professionals working in small units today fail to find the published tools for subject-based organization that are appropriate to their local needs, whether they are archivists, special librarians, information officers, or knowledge or content managers. Large established standards for document description and organization are too unwieldy, unnecessarily detailed, or too expensive to install and maintain. In other cases the available systems are insufficient for a specialist environment, or don't bring things together in a helpful way. A purpose built, in-house system would seem to be the answer, but too often the skills necessary to create one are lacking. This practical text examines the criteria relevant to the selection of a subject-management system, describes the characteristics of some common types of subject tool, and takes the novice step by step through the process of creating a system for a specialist environment. The methodology employed is a standard technique for the building of a thesaurus that incidentally creates a compatible classification or taxonomy, both of which may be used in a variety of ways for document or information management. Key areas covered are: What is a thesaurus? Tools for subject access and retrieval; what a thesaurus is used for? Why use a thesaurus? Examples of thesauri; the structure of a thesaurus; thesaural relationships; practical thesaurus construction; the vocabulary of the thesaurus; building the systematic structure; conversion to alphabetic format; forms of entry in the thesaurus; maintaining the thesaurus; thesaurus software; and; the wider environment. Essential for the practising information professional, this guide is also valuable for students of library and information science.

Trickey): "Vanda has provided a very useful work that will enable any reader who is prepared to follow her instruction to produce a thesaurus that will be a quality language-based subject access tool that will make the task of information retrieval easier and more effective. Once again I express my gratitude to Vanda for producing another excellent book." - Electronic Library 24(2006) no.6, S.866-867 (A.G. Smith): "Essential thesaurus construction is an ideal instructional text, with clear bullet point summaries at the ends of sections, and relevant and up to date references, putting thesauri in context with the general theory of information retrieval. But it will also be a valuable reference for any information professional developing or using a controlled vocabulary." - KO 33(2006) no.4, S.215-216 (M.P. Satija)
