Trigger Events at Portico

Publishers and libraries have entrusted thousands of titles to Portico for digital preservation. Campus-wide access to this preserved content is granted to libraries supporting Portico when specific conditions are met that cause titles to no longer be available from the publisher or any other source. These specific conditions are often called trigger events and include:

  • A publisher stops operations, or
  • A publisher ceases to publish a title, or
  • A publisher no longer offers back issues, or
  • Upon catastrophic and sustained failure of a publisher's delivery platform.

The following titles have been “triggered” and are available to all Portico participants through the Portico website, regardless of whether the participating institution has previously licensed the content.
