Portico An Electronic Archiving Service Ken DiFiore, MLS Associate Director of Library Relations, Portico Orbis-Cascade October 6, 2006

Digital Preservation: Greatly Desired Teaching and research rely upon access to scholarship of past generations. Preservation of print resources lay primarily with libraries, but today’s scholarship is increasingly published electronically. Both publishers and libraries face the problem of the long-term preservation of electronic information resources for future access.

Introduction Mission Statement - to preserve scholarly literature published in electronic form and to ensure that these materials remain available to future generations of scholars, researchers, and students. Structure - a not-for-profit organization with a mission and singular focus to provide a centralized, permanent archive of electronic scholarly journals. Philosophy - to be a trusted, third-party archive open to all peer-reviewed journals and one that balances the interests of libraries and publishers.

History In 2002, JSTOR initiated a project known as the Electronic-Archiving Initiative, the precursor to Portico. The goal was to facilitate the community’s transition to reliance upon electronic scholarly journals by developing a technological infrastructure and sustainable archive able to preserve scholarly e- journals. Portico was launched in 2005 by JSTOR and Ithaka, with support from The Andrew W. Mellon Foundation.

History In 2005, Archive support model for publishers announced; initial group of publisher participants signed. –Currently have 19 publishers entrusting journal content –Over 3,900 titles In 2006, Archive begins to ingest and maintain e- journal content. –16,000 articles in Archive –20,000 articles per month (July target) –45,000 articles per month (September target) In 2006, Archive support model for libraries announced; initial group of library participants signed. –128 committed libraries

Portico’s Approach to E-Journal Archiving Portico preserves the intellectual content of the journal, including the text, images, and limited functionality such as internal linking. “Look and feel” and publishers’ value-add features are not preserved. Publishers deliver to Portico the “source files” of electronic journals (SGML, XML, PDF, etc) shortly after initial publication. Managed Preservation - process is focused on long- term preservation requirements rather than immediate content access. Migration - usability maintained by migrating content to future file formats as technology evolves.

Portico’s Access Model Portico offers access to archived content to only those libraries supporting the archive financially. Access is offered only when specific trigger event conditions prevail and when titles are no longer available from the publisher or other sources. Libraries may also rely upon the Portico archive for post-cancellation or “perpetual” access, if a publisher chooses to name Portico as one of the mechanisms designated to meet this obligation. Until a trigger event occurs select librarians at participating libraries are granted password-controlled access for archive audit and verification purposes.

Sources of Support Support for the archive comes from the primary beneficiaries of the archive - publishers and libraries. Publishers committed to archiving more than 3,900 journals in Portico to date include: –Elsevier * - Berkeley Electronic Press * - Now Publishers –American Mathematical Society * - UK Serials Group * - Johns Hopkins U Press –John Wiley & Sons, Inc. * - Symposium Journals - JBJS –University of Chicago Press - Sage * –Oxford University Press * - SIAM * –American Anthropological Association * - IOP –BioOne *- AIP –Copernicus Publications *- Annual reviews * Agreed to allow Portico to fulfill perpetual access claims

Sources of Support Publishers and libraries support ongoing operations, maintenance and enhancement of the archive’s technological infrastructure, and content migrations as technology evolves. Publishers make an annual Supporting Publisher Contribution ranging from $250 to $75,000. Libraries make an Annual Archive Support payment ranging from $1,500 to $24,000. The Annual Archive Support payment is based upon a library’s total Library Materials Expenditures (LME) reflecting Portico’s role in protecting a critical component of library collections.

Role for Publishers Articulate your archival strategy to libraries. Participate in at least one archival arrangement. Monitor digital preservation developments and efforts. Monitor related legal developments, including legal deposit, e-content copyright registration and the Section 108 Working Group.

Publisher Benefits Reduces (or eliminates) publisher’s internal archiving costs. Meets library demand for a trusted, third-party archive. Meets library demand for perpetual access without negative impact on publisher’s operations. Converts source files to archival format and conducts future format migrations.

Benefits to Libraries Facilitates the transition to reliance upon electronic resources. Provides a practical mechanism to address “perpetual access” needs. Shared infrastructure or “virtual stacks” reduces preservation costs system wide. May enable savings through reduced processing and storage of print resources. Provides a means of assuring access to e-resources over the long term and protects against gaps in library collections.
