From a Portico Announcement:
Portico is pleased to announce the addition of two Gale Digital Collections – Nineteenth Century Collections Online and National Geographic Magazine Archive, 1888-1994 to Portico’s D-Collections Service. Portico has already preserved more than 1,380,000 objects and 83,000,000 files from 14 Gale Collections previously committed to the archive.
These new collections represent a wide range of content types, including monographs, newspapers, journals, and manuscripts.
In accordance with Portico’s D-Collections Service model, Portico will make the content available to Gale’s customers under specifically defined circumstances called “trigger events.” Should the content no longer be made available through the Gale system or from other sources, or if Gale were to experience an extended service interruption, Portico will make the content preserved in the archive available to Gale’s customers. There is no charge from Gale to its customers for this service.
