From a Portico Announcement:
Cambridge University Press will preserve its Cambridge Books Online content with Portico. 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.”
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.
