I just start reading a book entitled 'How to build a digital library'. And I found that the software recommended in this book is called Greenstone Digital Library Software. Click here for details
Greenstone is a suite of software for building and distributing digital library collections. It provides a new way of organizing information and publishing it on the Internet or on CD-ROM. Greenstone is produced by the New Zealand Digital Library Project at the University of Waikato, and developed and distributed in cooperation with UNESCO and the Human Info NGO. It is open-source, multilingual software, issued under the terms of the GNU General Public License. Read the Greenstone Factsheet for more information.
I enjoy this manoeuvre....
