The decentralized, cooperative, preservation and archiving model embodied in the LOCKSS Program capitalizes on the traditional roles of libraries and publishers. The open source software enables institutions to locally collect, store, preserve, and archive web based journals thus safeguarding their community’s access to that content. The model enforces the publisher’s access control systems and, for many publishers, does no harm to their business models. The LOCKSS Program is moving towards implementation by: • Building production quality software • Exploring best practices for collection development • Specifying collection management requirements, including metadata • Founding an Alliance for longer term support of the program
