Backups, system redundancies, and byte-level replication are all helpful but don’t guarantee reliable preservation well into the future. True digital preservation ensures four key factors over the very long term:</p> <div class="h3 bottom-margin-small">1. Usability</div> <p><strong>The intellectual content of the item must remain usable with changing technology.</strong><br/> We monitor our content for any threats of mediating technologies becoming obsolescent and take appropriate actions to make sure that the content remains usable.</p> <div class="h3 bottom-margin-small">2. Authenticity</div> <p><strong>The content needs to be an authentic replica of the original, and its provenance must be verifiable.</strong><br/> We maintain an audit trail of the content we get and what we do with it. If we transform the content, then Portico keeps the original file, the new file we created, and all related information.</p> <div class="h3 bottom-margin-small">3. Discoverability</div> <p><strong>The content must have logical bibliographic metadata so that it can be found through time.</strong><br/> All content preserved in Portico is accompanied by detailed metadata to ensure that they can always be found.</p> <div class="h3 bottom-margin-small">4. Accessibility</div> <p><strong>The content must be available for use.</strong><br/> <a href="/web/20200926062244/https://www.portico.org/for-participants/#triggered">Triggered titles</a> in Portico are available for research and pedagogical use to all students, staff, and faculty of participants in the corresponding service.</p> <p class="top-margin-m">To meet these goals, we have defined and follow <a href="/web/20200926062244/https://www.portico.org/our-work/preservation-step-step/">exacting standards and processes</a> for content management and maintenance and replication of the archive. We conduct checks and third-party archive certifications to guarantee quality and security and maintain a delivery system and services to provide easy access to publishers and libraries. And, while the archive is “dark” (i.e., under restricted user access), publishers and libraries are provided with <a href="/web/20200926062244/https://www.portico.org/for-participants/#audit">audit privileges</a> that allow them to review preserved content and its status.</p> </div> </section> </article> </div> </div> <aside class="sidebar-right medium-4 small-12 columns"> <div class=" " data-sc="content:module"> <div class="callout featured po-module module-id-1928 media-object stack light-tan module-no-date" data-equalizer-watch="" data-sc-name="Webinar_2017_Portico e-Book Preservation – Progress Made, Lessons Learned, and Future Directions"> <div class="h2">Portico e-Book Preservation: Progress Made, Lessons Learned, and Future Directions</div> <div class="module-date">Center for Research Libraries webinar recording</div> <p>By Stephanie Orphan and Amy Kirchhoff</p> <p><a href="https://web.archive.org/web/20200926062244/https://www.crl.edu/events/webinar-portico-e-book-preservation-%E2%80%93-progress-made-lessons-learned-and-future-directions">Description</a><br/> <a href="https://web.archive.org/web/20200926062244/https://www.crl.edu/sites/default/files/event_materials/Portico%20EbookPreservation2017.v2.pdf">Slides</a></p> <a href="https://web.archive.org/web/20200926062244/https://youtu.be/EN59YjIdoZI" class="button" data-sc="but click:module:cta" data-category="modules" data-action="cta - Webinar_2017_Portico e-Book Preservation – Progress Made, Lessons Learned, and Future Directions">Watch on YouTube</a> </div> </div>   </aside> </div> </main> <footer class="footer" aria-label="footer"> <div class="row"> <div class="small-12 columns"> <h4 class="h2 heading mb1">Portico</h4> </div> </div> <div class="row bottom-section"> <div class="small-12 medium-6 columns"> <div class="row"> <div class="columns large-4"> <ul class="no-bullet compact-bottom"> <li><a href="/web/20200926062244/https://www.portico.org/why-portico/">Why Portico</a></li> <li><a href="/web/20200926062244/https://www.portico.org/our-work/">Our work</a></li> <li><a href="/web/20200926062244/https://www.portico.org/coverage/">Coverage</a></li> <li><a href="/web/20200926062244/https://www.portico.org/join/">Join</a></li> <li><a href="/web/20200926062244/https://www.portico.org/news/">News</a></li> </ul> </div> <div class="columns large-4"> <ul class="no-bullet compact-bottom"> <li><a href="/web/20200926062244/https://www.portico.org/for-participants/">For participants</a></li> <li><a href="/web/20200926062244/https://www.portico.org/preservation-policies/">Preservation policies</a></li> <li><a href="https://web.archive.org/web/20200926062244/http://audit.portico.org/">Auditor login</a></li> </ul> </div> <div class="columns large-4"> <ul class="no-bullet compact-bottom"> <li><a href="/web/20200926062244/https://www.portico.org/our-staff/">Our staff</a></li> <li><a href="/web/20200926062244/https://www.portico.org/governance/">Governance</a></li> <li><a href="/web/20200926062244/https://www.portico.org/contact-us/">Contact us</a></li> <li><a href="https://web.archive.org/web/20200926062244/https://www.ithaka.org/careers/">Careers</a></li> </ul> </div> </div></div> <div class="small-12 medium-6 columns"> <ul class="no-bullet list-horizontal social-icons compact-bottom"> <li> <a href="https://web.archive.org/web/20200926062244/https://twitter.com/Portico_Digital" class="icon-link"> <span class="show-for-sr">Twitter</span> <i class="fi-social-twitter"></i> </a> </li> </ul> <p> <small> The Portico digital preservation service is part of <a href="https://web.archive.org/web/20200926062244/https://www.ithaka.org/">ITHAKA</a>, a not-for-profit organization helping the academic community use digital technologies to preserve the scholarly record and to advance research and teaching in sustainable ways. </small> </p> <p class="compact-bottom"> <small> ©2005-2020.
