Portico

Excerpt from DPC Annual Report 2008-2009

Portico, a part of the not-for-profit ITHAKA, preserves scholarly literature published in electronic form and ensures that these materials remain accessible to future scholars, researchers and students. More than 10,300 e-journals and 26,000 e-books from 83 publishers representing more than 2,000 scholarly societies and associations are committed to the Portico archive. In addition, nearly 650 libraries from fourteen countries support and rely upon the archive for long-term preservation of materials core to their collections.

The Portico archive is “dark” and opens for use by faculty and students only when access to particular a journal or book has been lost to library participants through discontinuation or other “trigger events” (www.portico.org/news/trigger.html). Through August 2009, four journals have been opened for campus-wide use to participating libraries.
