Long-term preservation 

Digital preservation is a vital part of the scholarly communications infrastructure. We are committed to the long-term preservation of all scholarly content as published on Wiley Online Library. Our authors, funders, and library partners can be assured of the long-term availability and preservation of their published, funded, and purchased content. 

We collaborate with industry-leading digital archive providers to ensure the future availability of digital content. 

Our key preservation partners include: 

• CLOCKSS, a not-for-profit joint venture between the world’s leading academic publishers and research libraries whose mission is to build a sustainable, geographically distributed dark archive with which to ensure the long-term survival of Web-based scholarly publications for the benefit of the greater global research community. "Triggered” content is available for free. CLOCKSS uniquely assigns this abandoned and orphaned content a Creative Commons license to ensure it remains available forever. Wiley is a founding member and participant in the CLOCKSS initiative for online journals, books and reference works.  Find out more here: www.clockss.org. 
   
• Portico, a community supported “dark archive” committed to ensuring that scholarly content published in electronic form remains accessible for the long term.  Portico has been working with publishers to preserve digital content since 2005 and has been certified as a trustworthy digital repository by the Center for Research Libraries.  Originally started by JSTOR with funding from the Library of Congress and the Mellon Foundation, today Portico is part of the non-profit organization ITHAKA (www.ithaka.org).  Wiley participates in the Portico initiative for online journals, books, and Cochrane content, and has recently signed a license for the preservation of Wiley Digital Archives in their d-collections service.  Learn more about their work here: www.portico.org/our-work/  

How digital preservation works 

In the event content is no longer available through Wiley due to the cessation of operations, any circumstances which prevent Wiley offering ongoing access, or catastrophic and sustained failure of our delivery platform for longer than 90 days, all digitally preserved content in CLOCKSS and Portico remains accessible and usable for researchers, scholars, and students now and into the future, in all circumstances. 

Open Access content is preserved alongside paywalled content, protecting authors and funders, ensuring all published content remains part of the scholarly record in perpetuity. 

National libraries 

Wiley collaborates with national libraries worldwide to ensure relevant materials are made available for deposit and preservation as required by national legislation, such as Legal Deposit programs in the United Kingdom and Australia.
