Sustaining the Archive

Portico must cover its operating costs from diversified funding sources and avoid the vulnerability that comes from reliance upon any single revenue stream. The chief beneficiaries of the archive - publishers and academic institutions - must form the primary sources of funding; however, charitable foundations and government agencies will also be expected to provide support. Initial support for Portico is provided by The Andrew W. Mellon Foundation, Ithaka, The Library of Congress, and JSTOR.

Contributions from Publishers

Publishers are asked to make annual contributions to defray the initial cost of developing content processing tools and storage infrastructure and the ongoing cost for content ingestion, migration, and archiving. Supporting publishers' annual contributions are tiered and vary according to the size of their annual journal revenue (print and electronic subscriptions, licensing and advertising). Publishers also agree to supply electronic journal source files in a timely way.

Contributions from Libraries

Libraries are asked to make an annual support payment to defray a portion of the archive's ongoing operational costs. Library payments are tiered according to a library's self-reported total Library Materials Expenditure (LME). Portico works with library systems and consortia to offer modest discounts.
