Portico is a service of the not-for-profit organization ITHAKA. Portico preserves digital publications such as e-journal articles, e-books, and digitized historical collections. Portico maintains that content in a "dark," or offline archive, to be made accessible to eligible libraries if and when the content becomes unavailable from its publisher. The purpose of Portico is to protect library and publisher investment in e-content by ensuring the long-term accessibility of that content to their communities.
