Tomorrow's LIS professionals will have to be conversant with all the tools and techniques for organizing information in different domains - from the library's shelves to the web and digital libraries. This core text covers the organization of the entire spectrum of information, and the principles, tools and techniques needed to do this effectively. The most up-to-date textbook yet available on this subject, this comprehensive book covers everything from traditional cat and class, through to metadata, information architecture and the semantic web. Written by experienced lecturers in the subject, who have authored several other successful textbooks, this book provides both an overview of the whole field of information organization, as well as an easy-to- understand introduction to each of the individual topics, which can be followed up with further study by following the references at the end of each chapter. A key student text for all information and library studies courses, the book is also useful for practising LIS professionals who need an understanding of the various tools and techniques they need to master to effectively organize information.
