Noor,
Are you asking about the library management system that ZU library uses? If that is the case, it is known as The Millennium integrated library system. If you need more information about it, you may want to talk to a librarian, or read some background information about the product on https://www.iii.com/products/millennium. If this is not the information you are looking for, it may be necessary to visit the library reference desk and talk to a librarian.
All the best.
