COPYRIGHT AND PERMISSIONS
ALDiJ guarantees that all published material will be available for perpetuity. ALDiJ is a subscriber member to the Portico digital preservation service provided by ITHAKA, a not-for-profit organization with a mission to help the academic community use digital technologies to preserve the scholarly record and to advance research and teaching in sustainable ways.
Portico acts as an independent back up repository for publishers’ online content. Membership of Portico demonstrates a publisher’s commitment to ensuring that valuable material they have published will always be available independent of the publisher’s own existence.
What Portico does:
Portico provides access to its library participants when specific conditions or “trigger events” occur, which may cause journal titles to no longer be available from the publisher or any other source such as:
- When a publisher ceases operations and titles are no longer available from any other source
- When a publisher ceases to publish and offer a title, and it is not offered by another publisher or entity
- When back issues are removed from a publisher’s offering and are not available elsewhere
- Upon catastrophic failure by a publisher’s delivery platform for a sustained period of time
When e-journal titles have “triggered,” they are available to all participants in the Portico E-Journal Preservation Service, regardless of whether the participating institution has previously licensed the content.
