    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
    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
    This book outlines the human side of the information seeking process, and focuses on the aspects of this process that can best be supported by the user interface. It describes the methods behind user interface design generally, and search interface design in particular, with an emphasis on how best to evaluate search interfaces. It discusses research results and current practices surrounding user interfaces for query specification, display of retrieval results, grouping retrieval results, navigation of information collections, query reformulation, search personalization, and the broader tasks of sensemaking and text analysis. Much of the discussion pertains to Web search engines, but the book also covers the special considerations surrounding search of other information collections.

    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.

    Abstract
    The World Wide Web is rapidly filling with more text than anyone could have imagined even a short time ago, but the task of isolating relevant parts of this vast information has become just that much more daunting. Richard Belew brings a cognitive perspective to the study of information retrieval as a discipline within computer science. He introduces the idea of Finding Out About (FDA) as the process of actively seeking out information relevant to a topic of interest and describes its many facets - ranging from creating a good characterization of what the user seeks, to what documents actually mean, to methods of inferring semantic clues about each document, to the problem of evaluating whether our search engines are performing as we have intended. Finding Out About explains how to build the tools that are useful for searching collections of text and other media. In the process it takes a close look at the properties of textual documents that do not become clear until very large collections of them are brought together and shows that the construction of effective search engines requires knowledge of the statistical and mathematical properties of linguistic phenomena, as well as an appreciation for the cognitive foundation we bring to the task as language users. The unique approach of this book is its even handling of the phenomena of both numbers and words, making it accessible to a wide audience. The textbook is usable in both undergraduate and graduate classes on information retrieval, library science, and computational linguistics. The text is accompanied by a CD-ROM that contains a hypertext version of the book, including additional topics and notes not present in the printed edition. In addition, the CD contains the full text of C.J. "Keith" van Rijsbergen's famous textbook, Information Retrieval (now out of print). Many active links from Belew's to van Rijsbergen's hypertexts help to unite the material. Several test corpora and indexing tools are provided, to support the design of your own search engine. Additional exercises using these corpora and code are available to instructors. Also supporting this book is a Web site that will include recent additions to the book, as well as links to sites of new topics and methods.

    Abstract
    In Digital Methods, Richard Rogers proposes a methodological outlook for social and cultural scholarly research on the Web that seeks to move Internet research beyond the study of online culture. It is not a toolkit for Internet research, or operating instructions for a software package; it deals with broader questions. How can we study social media to learn something about society rather than about social media use? How can hyperlinks reveal not just the value of a Web site but the politics of association? Rogers proposes repurposing Web-native techniques for research into cultural change and societal conditions. We can learn to reapply such "methods of the medium" as crawling and crowd sourcing, PageRank and similar algorithms, tag clouds and other visualizations; we can learn how they handle hits, likes, tags, date stamps, and other Web-native objects. By "thinking along" with devices and the objects they handle, digital research methods can follow the evolving methods of the medium. Rogers uses this new methodological outlook to examine the findings of inquiries into 9/11 search results, the recognition of climate change skeptics by climate-change-related Web sites, the events surrounding the Srebrenica massacre according to Dutch, Serbian, Bosnian, and Croatian Wikipedias, presidential candidates' social media "friends," and the censorship of the Iranian Web. With Digital Methods, Rogers introduces a new vision and method for Internet research and at the same time applies them to the Web's objects of study, from tiny particles (hyperlinks) to large masses (social media).

    Abstract
    Google[trademark] has become a nearly omnipresent tool of the Internet, with its potential only now beginning to be realised. How can librarians effectively integrate this powerful search engine to provide service to their patrons? "Libraries and Google[trademark]" presents leading authorities discussing the many possibilities of using Google products as effective, user-friendly tools in libraries. Google Scholar and Print are extensively explored with an eye towards offering an expanded view of what is and may be possible for the future, with practical insights on how to make the most of the product's capabilities.

    Co-published simultaneously as Internet reference services quarterly, vol. 10(1005), nos. 3/4 Rez. in: ZfBB 54(2007) H.2, S.98-99 (D. Lewandowski): "Google und Bibliotheken? Meist hat man leider den Eindruck, dass hier eher ein oder gedacht wird. Dies sehen auch die Herausgeber des vorliegenden Bandes und nehmen deshalb neben Beiträgen zur Diskussion um die Rolle der Bibliotheken im Zeitalter von Google auch solche auf, die Tipps zur Verwendung unterschiedlicher Google-Dienste geben. Die allgemeine Diskussion um Google und die Bibliotheken dreht sich vor allem um die Rolle, die Bibliotheken (mit ihren Informationsportalen) noch spielen können, wenn ihre Nutzer sowieso bei Google suchen, auch wenn die Bibliotheksangebote (zumindest von den Bibliothekaren) als überlegen empfunden werden. Auch wenn die Nutzer geschult werden, greifen sie doch meist lieber zur einfachen Recherchemöglichkeit bei Google oder anderen Suchmaschinen - vielleicht lässt sich die Situation am besten mit dem Satz eines im Buch zitierten Bibliothekars ausdrücken: »Everyone starts with Google except librarians.« (5.95) Sollen die Bibliotheken nun Google die einfache Recherche ganz überlassen und sich auf die komplexeren Suchfragen konzentrieren? Oder verlieren sie dadurch eine Nutzerschaft, die sich mittlerweile gar nicht mehr vorstellen kann, dass man mit anderen Werkzeugen als Suchmaschinen bessere Ergebnisse erzielen kann? Diese sicherlich für die Zukunft der Bibliotheken maßgebliche Frage wird in mehreren Beiträgen diskutiert, wobei auffällt, dass die jeweiligen Autoren keine klare Antwort bieten können, wie Bibliotheken ihre Quellen so präsentieren können, dass die Nutzer mit der Recherche so zufrieden sind, dass sie freiwillig in den Bibliotheksangeboten anstatt in Google recherchieren. Den Schwerpunkt des Buchs machen aber nicht diese eher theoretischen Aufsätze aus, sondern solche, die sich mit konkreten Google-Diensten beschäftigen. Aufgrund ihrer Nähe zu den Bibliotheksangeboten bzw. den Aufgaben der Bibliotheken sind dies vor allem Google Print und Google Scholar, aber auch die Google Search Appliance. Bei letzterer handelt es sich um eine integrierte Hard- und Softwarelösung, die die Indexierung von Inhalten aus unterschiedlichen Datenquellen ermöglicht. Der Aufsatz von Mary Taylor beschreibt die Vor- und Nachteile des Systems anhand der praktischen Anwendung in der University of Nevada.
    Ebenfalls direkt aus der Praxis erhält der Leser Informationen zum Google-PrintProgramm. Robert Milne beschreibt die Zusammenarbeit von Google und der Universität Oxford. In diesem Aufsatz wird - was dem Autor natürlich nicht anzulasten ist - ein Problem des vorliegenden Werks deutlich: Viele Informationen sind doch von sehr beschränkter Haltbarkeit. Der Redaktionsschluss war im Frühsommer 2005, sodass sich in vielen Bereichen bereits neue Entwicklungen ergeben haben. Dies ist beim Print-Programm der Fall, vor allem wird es aber bei dem Hauptthema des Bandes, nämlich Google Scholar, deutlich. Dieser Dienst wurde im November 2004 gestartet und stieß auf unterschiedlichste Reaktionen, die (anhand von Beispielen amerikanischer Bibliotheken) im Beitrag von Maurice C. York beschrieben werden. Einige Bibliotheken nahmen den Dienst begeistert auf und verlinkten diesen mit Lob versehen auf ihren Websites. Andere reagierten gegenteilig und warnten vor dessen schlechter Qualität. Auch weil vorauszusehen war, dass Google Scholar bei den Nutzern gut ankommen würde, darf das folgende Statement von einer Bibliothekswebsite geradezu als ignorant gelten: Google Scholar »is wonderful for those who do not have access to the library's databases« (S.119). Wie nun die Scholar-Nutzer auf die Bibliotheksangebote gelenkt werden können, beschreibt der ironisch »Running with the Devil« betitelte Aufsatz von Rebecca Donlan und Rachel Cooke. Die Autorinnen beschreiben den Einsatz von Link-Resolvern und gehen auf die in Google Scholar bestehenden Probleme durch unklare Bezeichnungen in den Trefferlisten ein. Einige Beispiele zeigen, dass Google Scholar auch in Kombination mit der Verlinkung auf die Bibliotheksbestände keine befriedigende Recherchesituation herstellt, sondern vielmehr weitere Anstrengungen nötig sind, um »das Beste beider Welten« zusammenzuführen. Zwei weitere Aufsätze beschäftigen sich mit der Frage, wie gut Google Scholar eigentlich ist. Einmal geht es darum, wie gut Scholar den »ACRL Information Literacy Standards« genügt. Der zweite Beitrag vergleicht Google Scholar anhand von fünf Suchaufgaben einerseits mit einem lokalen Bibliothekskatalog, andererseits mit EBSCOs Academic Search Premier und jeweils einer fachspezifischen Datenbank. Die Ergebnisse zeigen keine durchgehende Überlegenheit einer Suchlösung, vielmehr wird deutlich, dass es auf die Auswahl des richtigen Suchwerkzeugs für die bestehende Suchanfrage ankommt bzw. dass erst eine Kombination dieser Werkzeuge zu optimalen Ergebnissen führt. Man könnte also auch hier wieder sagen: Google und Bibliotheken, nicht Google oder Bibliotheken.
