The Hiberlink plugin for Zotero assist authors in proactively archiving at-risk digital content. Zotero is a free, easy-to-use tool that help with collecting, organising, citing and sharing g research sources. (http://www.zotero.org/).
The Hiberlink plugin creates a backup of the reference with an archival service and keeps a record of this backup. Should the original resource change or disappear the plugin allows you to view the content as it was when you referenced it. The archived references can be exported and used to refer to the original resource in other publications. These are compatible with Memento (http://www.mementoweb.org/) protocol.
