LOCKSS (Lots of Copies Keep Stuff Safe)

Abstract: LOCKSS is open source, peer-to-peer software that functions as a persistent access preservation system. Information is delivered via the web, and stored using a sophisticated but easy to use caching system. Simply put, LOCKSS provides for Jefferson's "multiplication of copies," but with an electronic twist.

LOCKSS (for "Lots of Copies Keep Stuff Safe") is open source software that provides librarians with an easy and inexpensive way to collect, store, preserve, and provide access to their own, local copy of authorized content they purchase. Running on standard desktop hardware and requiring almost no technical administration, LOCKSS converts a personal computer into a digital preservation appliance, creating low-cost, persistent, accessible copies of e-journal content as it is published. Since pages in these appliances are never flushed, the local community's access to that content is safeguarded. Accuracy and completeness of LOCKSS appliances is assured through a robust and secure, peer-to-peer polling and reputation system.
