Abstract

Presents a general introduction to how libraries use electronic resources, ranging from document delivery services and electronic mail to the Internet and WWW. Explores the available resources and examines their impact on libraries, library provision of information and the way that library and information professionals and users respond to them. Specific sections consist of: history and evolution of electronic resources; the Internet and its applications; electronic publishing and document delivery services; interactive multimedia; virtual libraries and digital libraries; bibliography and references

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.
