Portico and Cambridge University Press have announced an agreement to preserve Cambridge Books Online content with Portico. Portico is a not-for-profit organization offering community-supported digital preservation service for e-journals, e-books and d-collections for libraries and institutions. As part of the agreement, Cambridge University Press will make “an annual contribution” to Portico to support its e-book preservation service.

The addition of titles from Cambridge Books Online brings the total number of e-books committed to the Portico archive to more than 123,000. Beginning in 2011, Portico expanded its preservation services offered to libraries with the introduction of separate e-book and e-journal services, enabling libraries to choose where to invest their preservation resources. Through this agreement, Cambridge extends its relationship with Portico, which began in 2006 with the publisher’s commitment to deposit its entire list of e-journals in the Portico archive.

“As more users turn to online access for books, a digital preservation strategy to ensure long-term access is absolutely vital,” stated Hannah Perrett, strategic development director, digital publishing, Cambridge University Press. “Portico’s E-Book Preservation Service provides publishers and libraries with a collaborative solution that we can all get behind.”
