Responding to the Preservation Challenge: Portico, an Electronic Archiving Service

ABSTRACT The preservation of physical materials has traditionally connected users to content. Today libraries face new challenges as they address mission-critical digital preservation. To achieve long-term preservation of e-resources, libraries need to: act now to be a part of at least one e-journal preservation program; recognize that digital preservation requires multiple methodologies; and recognize that the scale of the challenge requires multiple actors. Portico, which provides robust digital preservation of electronic scholarly resources, is one element of the emerging digital preservation infrastructure. Portico is a community-based, third party archive that brings together scholarly publishers and libraries from around the world.
