    Abstract
    Are we at a turning point in digital information? The expansion of the internet was unprecedented; search engines dealt with it in the only way possible - scan as much as they could and throw it all into an inverted index. But now search engines are beginning to experiment with deep web searching and attention to taxonomies, and the semantic web is demonstrating how much more can be done with a computer if you give it knowledge. What does this mean for the skills and focus of the information science (or sciences) community? Should information designers and information managers work more closely to create computer based information systems for more effective retrieval? Will information science become part of computer science and does the rise of the term informatics demonstrate the convergence of information science and information technology - a convergence that must surely develop in the years to come? Issues and questions such as these are reflected in this monograph, a collection of essays written by some of the most pre-eminent contributors to the discipline. These peer reviewed perspectives capture insights into advances in, and facets of, information science, a profession in transition. With an introduction from Jack Meadows the key papers are: Meeting the challenge, by Brian Vickery; The developing foundations of information science, by David Bawden; The last 50 years of knowledge organization, by Stella G Dextre Clarke; On the history of evaluation in IR, by Stephen Robertson; The information user, by Tom Wilson A; The sociological turn in information science, by Blaise Cronin; From chemical documentation to chemoinformatics, by Peter Willett; Health informatics, by Peter A Bath; Social informatics and sociotechnical research, by Elisabeth Davenport; The evolution of visual information retrieval, by Peter Enser; Information policies, by Elizabeth Orna; Disparity in professional qualifications and progress in information handling, by Barry Mahon; Electronic scholarly publishing and open access, by Charles Oppenheim; Social software: fun and games, or business tools? by Wendy A Warr; and, Bibliometrics to webometrics, by Mike Thelwall. This monograph previously appeared as a special issue of the "Journal of Information Science", published by Sage. Reproduced here as a monograph, this important collection of perspectives on a skill set in transition from a prestigious line-up of authors will now be available to information studies students worldwide and to all those working in the information science field.

    Rez. in: Mitt VÖB 62(2009) H.3, S.95-99 (O. Oberhauser): "Dieser ansehnliche Band versammelt 16 Beiträge und zwei Editorials, die bereits 2008 als Sonderheft des Journal of Information Science erschienen sind - damals aus Anlass des 50. Jahrestages der Gründung des seit 2002 nicht mehr selbständig existierenden Institute of Information Scientists (IIS). Allgemein gesprochen, reflektieren die Aufsätze den Stand der Informationswissenschaft (IW) damals, heute und im Verlauf dieser 50 Jahre, mit Schwerpunkt auf den Entwicklungen im Vereinigten Königreich. Bei den Autoren der Beiträge handelt es sich um etablierte und namhafte Vertreter der britischen Informationswissenschaft und -praxis - die einzige Ausnahme ist Eugene Garfield (USA), der den Band mit persönlichen Reminiszenzen beschließt. Mit der nunmehrigen Neuauflage dieser Kollektion als Hardcover-Publikation wollten Herausgeber und Verlag vor allem einen weiteren Leserkreis erreichen, aber auch den Bibliotheken, die die erwähnte Zeitschrift im Bestand haben, die Möglichkeit geben, das Werk zusätzlich als Monographie zur Aufstellung zu bringen. . . . Bleibt die Frage, ob eine neuerliche Publikation als Buch gerechtfertigt ist. Inhaltlich besticht der Band ohne jeden Zweifel. Jeder, der sich für Informationswissenschaft interessiert, wird von den hier vorzufindenden Texten profitieren. Und: Natürlich ist es praktisch, eine gediegene Buchpublikation in Händen zu halten, die in vielen Bibliotheken - im Gegensatz zum Zeitschriftenband - auch ausgeliehen werden kann. Alles andere ist eigentlich nur eine Frage des Budgets." Weitere Rez. in IWP 61(2010) H.2, S.148 (L. Weisel); JASIST 61(2010) no.7, S.1505 (M. Buckland); KO 38(2011) no.2, S.171-173 (P. Matthews): "Armed then with tools and techniques often applied to the structural analysis of other scientific fields, this volume frequently sees researchers turning this lens on themselves and ranges in tone from the playfully reflexive to the (parentally?) overprotective. What is in fact revealed is a rather disparate collection of research areas, all making a valuable contribution to our understanding of the nature of information. As is perhaps the tendency with overzealous lumpers (see http://en.wikipedia.org/wiki/Lumpers_and_splitters), some attempts to bring these areas together seem a little forced. The splitters help draw attention to quite distinct specialisms, IS's debts to other fields, and the ambition of some emerging subfields to take up intellectual mantles established elsewhere. In the end, the multidisciplinary nature of information science shines through. With regard to future directions, the subsumption of IS into computer science is regarded as in many ways inevitable, although there is consensus that the distinct infocentric philosophy and outlook which has evolved within IS is something to be retained."

    Abstract
    Class-tested and coherent, this textbook teaches information retrieval, including web search, text classification, and text clustering from basic concepts. Ideas are explained using examples and figures, making it perfect for introductory courses in information retrieval for advanced undergraduates and graduate students. Slides and additional exercises are available for lecturers. - This book provides what Salton and Van Rijsbergen both failed to achieve. Even more important, unlike some other books in IR, the authors appear to care about making the theory as accessible as possible to the reader, on occasion including short primers to certain topics or choosing to explain difficult concepts using simplified approaches. Its coverage [is] excellent, the quality of writing high and I was surprised how much I learned from reading it. I think the online resources are impressive.

    Abstract
    This book discusses many of the key design issues for building search engines and emphazises the important role that applied mathematics can play in improving information retrieval. The authors discuss not only important data structures, algorithms, and software but also user-centered issues such as interfaces, manual indexing, and document preparation. They also present some of the current problems in information retrieval that many not be familiar to applied mathematicians and computer scientists and some of the driving computational methods (SVD, SDD) for automated conceptual indexing

    Abstract
    The second edition of Understanding Search Engines: Mathematical Modeling and Text Retrieval follows the basic premise of the first edition by discussing many of the key design issues for building search engines and emphasizing the important role that applied mathematics can play in improving information retrieval. The authors discuss important data structures, algorithms, and software as well as user-centered issues such as interfaces, manual indexing, and document preparation. Significant changes bring the text up to date on current information retrieval methods: for example the addition of a new chapter on link-structure algorithms used in search engines such as Google. The chapter on user interface has been rewritten to specifically focus on search engine usability. In addition the authors have added new recommendations for further reading and expanded the bibliography, and have updated and streamlined the index to make it more reader friendly.
