Portico (www.portico.org/digital-preservation/) is pleased to announce that John Wiley & Sons has entered into an archive license agreement to preserve its collection of more than 8,000 online scholarly monographs. With this agreement, Wiley expands its relationship with Portico, which began in 2006 with Wiley’s commitment to deposit their entire list of e-journals to the Portico archive.

Wiley joins De Gruyter, Duke University Press, Elsevier, Palgrave Macmillan, SPIE, and Springer in participating in Portico’s e-book preservation service, which was introduced to scholarly publishers in mid-2008. The addition of Wiley’s 8,000 titles brings the total number of e-books committed to the Portico archive to more than 43,000.

Beginning in 2011, Portico will disaggregate its services into separate e-book and e-journal services for the library community in response to both the growth of the Portico archive, and to the community’s evolving preservation needs. The separate services will enable libraries to choose where to invest their preservation resources based on their collections, needs and budgets. Portico’s new e-book service for libraries will be similar to the existing e-journal service in that library access is governed by trigger events and post-cancellation access when appropriate.

Since 2005, the number of titles and types of content preserved in Portico has grown significantly. To date, over 11,000 e-journals and 43,000 e-books have been entrusted to the Portico archive.
