The New Zealand Digital Library project is a research programme at The University of Waikato whose aim is to develop the underlying technology for digital libraries and make it available publicly so that others can use it to create their own collections. Their web site provides several document collections, including historical documents, humanitarian and development information, computer science technical reports and bibliographies, literary works, and magazines. All are available over the Web, and can be accessed through searching and browsing interfaces provided by the Greenstone digital library software. Behind the query interface lies a huge collection providing gigabytes of information. This has been added to Research Resources Subject Tracer™ Information Blog and Deep Web Research Subject Tracer™ Information Blog.
