Digital preservation is the process of preserving information in the digital form. By digital form we mean a non- print form. Information is moving from print to web (non-print) and it has become easy for masses especially the scholarly population to access information on the web from anywhere 24*7. Since digital information is more prone to damage and loss than print information, therefore, it is imperative to protect access to this information not only for the benefit of present but for future generation as well. Various initiatives and policies are currently in place to ensure the long term preservation of digital information. LOCKSS, CLOCKSS, and PORTICO are the three major digital preservation initiatives aimed at protecting and preserving the digital content for its long term access and use. The current study provides an overview of how these three initiatives started and how these policies function in collaboration with publishers and libraries for long term digital content preservation.
