How to Build a Digital Library is the only book that offers all the knowledge and tools needed to construct and maintain a digital library, regardless of the size or purpose. It is a perfectly self-contained resource for individuals, agencies, and institutions wishing to put this powerful tool to work in their burgeoning information treasuries.The Second Edition reflects new developments in the field as well as in the Greenstone Digital Library open source software. In Part I, the authors have added a new chapter on user groups, user support, collaborative browsing, and user contributions. New material on content-based queries, map-based queries, cross-media queries, and an increased emphasis placed on multimedia by adding a "digitizing" section to each major media type. A new chapter has been added on "Internationalization: The Global Challenge" which will address Unicode standards, multi-language interfaces and collections, and issues with non-European languages such as Chinese, or Hindi. Part II, the software tools section, has been completely rewritten to reflect new developments in Greenstone Digital Library Software, an internationally popular open source software tool with a comprehensive graphical facility for creating and maintaining digital libraries. Additoinal content is available at the web site, www.greenstone.org/howto. Implemented as a digital library, the website provides access to color versions of all figures, two online appendices , a full-text sentence-level index, and an automatically generated glossary of acronyms and their definitions.
