[edit] Public vs. Private LOCKSS Networks
LOCKSS is currently being used to preserve content in two distinct types of environments: a public LOCKSS network holds material of general interest to a wide community. Private LOCKSS networks hold material for smaller communities.
The public network preserves materials that are generally available on the web, including subscription-only material. Anyone can participate in this network for free. Sufficient replication is ensured because the materials preserved in the public network are those that the wider community has agreed they wish to preserve. The public network is maintained by the Stanford University-based LOCKSS staff with funding provided by the LOCKSS Alliance. As of fall 2008, the public network comprised over 200 libraries worldwide, with committed titles from over 400 publishers. LOCKSS Alliance members have access to, and can preserve, all the titles to which they subscribe.
Materials of interest to a small community or that is sensitive, such as that held by government agencies, may be preserved in a Private LOCKSS Network.
