Book Description
The Subject Approach to Information is a highly readable, comprehensive study of information retrieval methods. For the fourth edition, Professor Foskett has revised and and updated his work to include current developments in all aspects of information storage and retrieval by the subject approach. The theme of the work is the basic similarity of all methods of information retrieval, and the problems which need to be solved in order to obtain good results from any system. The book opens with a consideration of the theory of information retrieval systems and explores both the difficulties and the potential of using computers in this field. The problems and uses of the different pre-coordinate and post-coordinate systems and languages are studied in depth, and there is a close examination of computer-based systems, including videotext and text retrieval, as well as more conventional reference retrieval systems such as DIALOG and Euronet/DIANE. A final chapter describes and discusses a selection of significant evaluative studies in information retrieval.

Book Description
The Internet and World Wide Web have made access to information easy but do not solve the problems of finding exactly what is wanted, to the point of overwhelming the reader with information. Since the first edition of this classic librarianship text appeared, the development of computer technology has meant that the organization of information has become a hugely complex area. This fifth edition places emphasis on the intellectual effort required to make meaningful use of the enormous amount of information now accessible to the searcher. Fully revised and updated in comprehensive detail that includes bibliographies, ample examples and quotations, it focuses on: information retrieval systems database access systems online searching and OPACs hypertext networked systems. Foskett describes how we search for information by looking at the problems involved, at the theoretical principles suggested as solutions and their practical realization as classification schemes, lists of subject headings and thesauri. Readership: This influential text is widely acknowledged to be essential reading for all students of librarianship and information management, and an invaluable reference tool for practising library and information professionals.

Book Description
Information science has for a long time been drawing on the knowledge produced in psychology and related fields. This is reasonable, for the central issue in information science concerns individual users navigating information spaces such as libraries, databases, and the Internet. Thus, information seeking is the fundamental problem in information science, while other problems, such as document representation, are subordinate. This book proposes a general theory of information seeking as a theoretical basis for information science. The volume begins with an examination of subject representation and retrieval. It then considers subject analysis and the organization of knowledge, the interpretational processes by which documents are analyzed, and their explicit subject retrieval data are created. Existing theories are then criticized from four epistemological perspectives, and the author argues that information science should be based on methodological collectivism, in which society, rather than the individual, determines the meaning of knowledge. The work then analyzes information seeking as a methodologically collectivistic activity. The volume begins with an examination of subject representation and retrieval.

Book Description
Media literacy is often focused on evaluating the message rather than reflecting on the medium. Bringing together postphenomenology, media ecology, posthumanism, and complexity theory, Richard Lewis’s book offers a method for such a reflection and shows how our everyday media environments constitute us as (post)human subjects: one that is becoming and constitutes through relations – also with our media technologies. An original interdisciplinary effort – including for example the term 'intrasubjective mediation' – and a must-read book for everyone interested in how we become with and through technologies. Prof Mark Coeckelbergh, University of Vienna Technology, Media Literacy, and the Human Subject is a clearly and concisely written book that employs a fruitful transdisciplinary approach. It at once offers an excellent grounding in the literature, whilst simultaneously developing a useful tool for students to reflect deeply and critically upon their own engagement with media. Thoroughly recommended. Alexander Thomas, University of East London What does it mean to be media literate in today’s world? How are we transformed by the many media infrastructures around us? We are immersed in a world mediated by information and communication technologies (ICTs). From hardware like smartphones, smartwatches, and home assistants to software like Facebook, Instagram, Twitter, and Snapchat, our lives have become a complex, interconnected network of relations. Scholarship on media literacy has tended to focus on developing the skills to access, analyze, evaluate, and create media messages without considering or weighing the impact of the technological medium—how it enables and constrains both messages and media users. Additionally, there is often little attention paid to the broader context of interrelations which affect our engagement with media technologies. This book addresses these issues by providing a transdisciplinary method that allows for both practical and theoretical analyses of media investigations. Informed by postphenomenology, media ecology, philosophical posthumanism, and complexity theory the author proposes both a framework and a pragmatic instrument for understanding the multiplicity of relations that all contribute to how we affect—and are affected by—our relations with media technology. The author argues persuasively that the increased awareness provided by this posthuman approach affords us a greater chance for reclaiming some of our agency and provides a sound foundation upon which we can then judge our media relations. This book will be an indispensable tool for educators in media literacy and media studies, as well as academics in philosophy of technology, media and communication studies, and the post-humanities.

Book Description
Most introductory texts provide a technology-based survey of methods and techniques that leaves the reader without a clear understanding of the interrelationships between methods and techniques. By providing a strategy-based introduction, the reader is given a clear understanding of how to provide overlapping defenses for critical information. This understanding provides a basis for engineering and risk-management decisions in the defense of information. Information security is a rapidly growing field, with a projected need for thousands of professionals within the next decade in the government sector alone. It is also a field that has changed in the last decade from a largely theory-based discipline to an experience-based discipline. This shift in the field has left several of the classic texts with a strongly dated feel. Provides a broad introduction to the methods and techniques in the field of information security Offers a strategy-based view of these tools and techniques, facilitating selection of overlapping methods for in-depth defense of information Provides very current view of the emerging standards of practice in information security

Book Description
"Liaison librarianship is a well-established system for framing the work and organizational structures of an academic library to effectively meet the needs of faculty and students. But despite its rich history, the precise meaning of liaison librarianship remains somewhat fluid--the size and nature of an academic institution, the library's financial and human resources, and the diversity and size of local programs are only some of the variables that librarians must take into consideration when evaluating a specific liaison model for their library, how to implement it, and how its success will be assessed. Approaches to Liaison Librarianship showcases a number of different implementations of the liaison model, across a range of institutions, and describes in detail many of the tailored programs and services that liaison librarians are so well-positioned to provide" -- Publisher's description.
