Portico

Portico, a not-for-profit digital preservation service, is among the largest community-supported digital archives in the world.

Working with libraries and publishers, Portico preserves e-journals, e-books, and other electronic scholarly content to ensure researchers and students will have access to it in the future.

Portico is a service of ITHAKA (www.ithaka.org), a not-for-profit organisation dedicated to helping the academic community use digital technologies to preserve the scholarly record and to advance research and teaching in sustainable ways.

In 2010, Portico became the first preservation service to be independently audited by the Center for Research Libraries (CRL)   and certified as a trusted, reliable, digital preservation solution that serves the needs of the library community.
