The Greenstone Digital Library Software provides a way to build and distribute digital library collections by organizing information and making it available online or offline. It was developed by the New Zealand Digital Library Project at the University of Waikato in cooperation with UNESCO and the Human Info NGO to empower users to create their own digital libraries and share information, especially in developing countries. Greenstone allows users to compile documents, describe them with metadata, design collections, and build them into searchable digital libraries for publishing.
