    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.

    Abstract
    This book explores two main models of Information Literacy or IL: the SCONUL (Society of College, National and University Libraries) Seven Pillars of Information Skills and the IL competencies identified by the ALA (American Library Association). Practical examples for the development of IL skills identified by these models are illustrated using printed and web-based resources. The process of integrating IL provision within a programme of study is outlined to illustrate two strategies underpinning this integration at generic-skills level, the 'plug & play' approach, and at subject-specific level, the 'research skills approach'. A range of diagnostic and assessment methods, to monitor the iterative process of IL skills development, are also included.
