Aims to empower users, particularly in universities, libraries, and other publicservice institutions to build their own digital libraries (to avoid being read-onlysocieties)

The Greenstone developers hope that the software will encourage theeffective deployment of digital libraries to share information and place it inthe public domain

What GreenstoneYou cannot use Greenstone to automate your library, e.g., circulateyour books using computers

Greenstone IS NOT Library Automation softwareGreenstone IS NOT Scanning software

Greenstone ALLOWS you to BUILDDigital Libraries. It is not a DigitalLibrary in itselfGreenstone cannot be used for scanning. You first have to scan yourmaterials elsewhereAND THEN upload them into Greenstone

Greenstone IS NOT a Digital Library
