    Abstract
    Suchmaschinen ermöglichen den Zugang zu Informationen im Internet und machen es als grenzenloses Informationsportal nutzbar. Netzinhalte, die nicht durch Suchmaschinen auffindbar sind, existieren für die Internetnutzer gar nicht - ein großes Gefahrenpotenzial für den einzelnen Nutzer und die Gesellschaft. Der vorliegende Band beleuchtet das Phänomen aus kommunikationswissenschaftlicher, rechtlicher, pädagogischer und technischer Perspektive.

    Rez. in: Mitt. VOEB 68(2015) H.1, S.180-183 (O.Oberhauser): "Aus dieser kurzen Skizze geht hervor, dass der vorliegende Band eine Reihe interessanter und mitunter auch brisanter Teilthemen beinhaltet. Wer an der Diskussion um die Rolle der meistgenutzten Suchmaschine in unserer Gesellschaft Interesse hat, findet in diesem Buch reichlich Material und Ideen. Jeder Beitrag wird zudem durch ein Literaturverzeichnis ergänzt, in dem weiterführende Quellen genannt werden. Die Beiträge sind durchweg "lesbar" geschrieben und nur in mässigem Ausmass von soziologischem oder rechtswissenschaftlichem Fachjargon durchsetzt. In stilistischer Hinsicht ist der Text dennoch nicht ohne Probleme, zumal bereits im ersten Absatz der Einleitung ein als Hauptsatz "verkaufter" Nebensatz auffällt ("Denn Suchmaschinenbetreiber wie Google ermöglichen und gestalten den Zugang zu Informationen im Netz.") und die gleiche stilistische Schwäche allein in der 19-seitigen Einleitung in über einem Dutzend weiterer Fälle registriert werden kann, vom nächsten Beitrag gar nicht zu sprechen. Ein funktionierendes Verlagslektorat hätte derlei rigoros bereinigen müssen. Es hätte eventuell auch dafür Sorge tragen können, dass am Ende des Bandes nicht nur ein Verzeichnis der Autorinnen und Autoren aufscheint, sondern auch ein Sachregister - ein solches fehlt nämlich bedauerlicherweise. In optischer Hinsicht ist der Hardcover-Band ansprechend gestaltet und gut gelungen. Der Preis liegt mit rund 80 Euro leider in der Oberklasse; auch die E-Book-Version macht die Anschaffung nicht billiger, da kein Preisunterschied zur gebundenen Ausgabe besteht. Dennoch ist das Buch aufgrund der interessanten Inhalte durchaus zu empfehlen; grössere Bibliotheken sowie kommunikations- und informationswissenschaftliche Spezialsammlungen sollten es nach Möglichkeit erwerben."

    Abstract
    Information seeking is a fundamental human activity. In the modern world, it is frequently conducted through interactions with search systems. The retrieval and comprehension of information returned by these systems is a key part of decision making and action in a broad range of settings. Advances in data availability coupled with new interaction paradigms, and mobile and cloud computing capabilities, have created a broad range of new opportunities for information access and use. In this comprehensive book for professionals, researchers, and students involved in search system design and evaluation, search expert Ryen White discusses how search systems can capitalize on new capabilities and how next-generation systems must support higher order search activities such as task completion, learning, and decision making. He outlines the implications of these changes for the evolution of search evaluation, as well as challenges that extend beyond search systems in areas such as privacy and societal benefit.

    Abstract
    Practical Ontologies for Information Professionals provides an accessible introduction and exploration of ontologies and demonstrates their value to information professionals. More data and information is being created than ever before. Ontologies, formal representations of knowledge with rich semantic relationships, have become increasingly important in the context of today's information overload and data deluge. The publishing and sharing of explicit explanations for a wide variety of conceptualizations, in a machine readable format, has the power to both improve information retrieval and discover new knowledge. Information professionals are key contributors to the development of new, and increasingly useful, ontologies. Practical Ontologies for Information Professionals provides an accessible introduction to the following: defining the concept of ontologies and why they are increasingly important to information professionals ontologies and the semantic web existing ontologies, such as RDF, RDFS, SKOS, and OWL2 adopting and building ontologies, showing how to avoid repetition of work and how to build a simple ontology interrogating ontologies for reuse the future of ontologies and the role of the information professional in their development and use. This book will be useful reading for information professionals in libraries and other cultural heritage institutions who work with digitalization projects, cataloguing and classification and information retrieval. It will also be useful to LIS students who are new to the field.

    Abstract
    "Web Search Engine Research", edited by Dirk Lewandowski, provides an understanding of Web search engines from the unique perspective of Library and Information Science. The book explores a range of topics including retrieval effectiveness, user satisfaction, the evaluation of search interfaces, the impact of search on society, reliability of search results, query log analysis, user guidance in the search process, and the influence of search engine optimization (SEO) on results quality. While research in computer science has mainly focused on technical aspects of search engines, LIS research is centred on users' behaviour when using search engines and how this interaction can be evaluated. LIS research provides a unique perspective in intermediating between the technical aspects, user aspects and their impact on their role in knowledge acquisition. This book is directly relevant to researchers and practitioners in library and information science, computer science, including Web researchers.

    Abstract
    Throughout most of human history, people got the information they needed for their lives more or less automatically and unthinkingly--through people they talked with, and from their own life experiences. Today, we are inundated with information but often know little about how to find our way through the vast sea of recorded knowledge to get to what we really want and need. In the information sciences researchers have thought a great deal about information seeking, and have studied people in the grip of trying to satisfy an information need. Much has been learned about how to enable comfortable and fun information searching in human, paper, and digital environments. Professor Marcia Bates of UCLA's Department of Information Studies has collected fifteen of her major papers on information searching in theory and practice in this volume. The articles address many aspects of searching for information, including searching tactics and techniques, the "vocabulary problem" in online searching, the kinds of indexing terms to use in various contexts, the Bradford Distribution and its effects on searching in large databases, the true nature of browsing, and how to design computer interfaces for successful searching. For all the variety in types of information systems, the human being interacting with an information source is remarkably stable in psychology and behavior. These human traits and system features are explored in depth in this book. Bates' popular articles, "What is Browsing--Really?" and "The Design of Browsing and Berrypicking Techniques for the Online Search Interface," are included. This is Volume II of three containing selected works by Bates. The others are titled: Information and the Information Professions (Vol. I) and Information Users and Information System Design (Vol. III)

    Abstract
    Dealing with information is one of the vital skills in the 21st century. It takes a fair degree of information savvy to create, represent and supply information as well as to search for and retrieve relevant knowledge. How does information (documents, pieces of knowledge) have to be organized in order to be retrievable? What role does metadata play? What are search engines on the Web, or in corporate intranets, and how do they work? How must one deal with natural language processing and tools of knowledge organization, such as thesauri, classification systems, and ontologies? How useful is social tagging? How valuable are intellectually created abstracts and automatically prepared extracts? Which empirical methods allow for user research and which for the evaluation of information systems? This Handbook is a basic work of information science, providing a comprehensive overview of the current state of information retrieval and knowledge representation. It addresses readers from all professions and scientific disciplines, but particularly scholars, practitioners and students of Information Science, Library Science, Computer Science, Information Management, and Knowledge Management. This Handbook is a suitable reference work for Public and Academic Libraries.
