"This revised and updated edition takes account of the radical changes that have taken place since it was originally conceived. With almost 600 A-Z entries, written by a global team of over 180 contributors, the subject matter ranges from mobile library services provided by camel and donkey transport to search engines, portals and the World Wide Web. The entries fall into four categories." "All the longer entries are fully supported by references and suggestions for further reading. And with its comprehensive index and substantial cross-referencing, this new edition of the International Encyclopedia of Information and Library Science is destined to remain an invaluable tool both for reference and as a starting point for more in-depth study."--BOOK JACKET.
