Open-Source Automated Library System 

OPALS Open-source Automated Library System is a powerful cooperatively developed, Web-based, open source program. This alternative technology provides Internet access to information databases, library collections and digital archives. Many school, college, research, business, religious and library union catalogs (that provide ILL services) use OPALS. There is no need to install software or purchase expensive computer hardware or software licenses to implement this powerful, turnkey Internet accessible system. The “total cost of ownership” of this standards-based, Web-based, feature rich software is demonstrably and undeniably sustainable.
