Libraries and Preservation Many libraries are committed to providing enduring access as a core value Most have insufficient funds to preserve their holdings Only a few libraries make major investments in preservation

Double Bind Libraries are maintaining parallel formats at significant expense. Libraries won’t drop paper until publishers can guarantee electronic archiving. Readers expect both paper and digital. Publishers are maintaining parallel formats at significant expense.

Electronic archiving important –76% agree very well –21% agree somewhat Libraries should retain paper –48% very well –30% somewhat Faculty Survey

Which One is the Librarian? Publishers and librarians don’t trust one another. Publishers worry about loss of assets in an open archive. Librarians fret that commitment to the bottom line will overshadow intention to preserve.

Project Prism Describes risks in Web environment Develops risk management methodology Creates tools and policies for virtual remote control Web crawlers and other automated tools –Identify and quantify risks –Implement measures to prevent, mitigate, and recover from damage to and loss of Web-based assets

Mellon-Funded Journal Archiving Projects Move beyond discussion to action –Cornell (Agriculture) –Harvard (Individual publishers) –MIT (Dynamic Journals) –NYPL (Performing Arts) –Stanford (Archiving software, tools) –University of Pennsylvania (University Presses) –Yale (Elsevier)

Key Assumptions in Mellon Projects Archives should be independent of publishers Archiving is core mission of institution with archival responsibility. Archiving is for long-term (100 years or more- not daily use) Archives should conform to standards and best practices and be subject to auditing and certification. Open Archival Information System as basis

Functions of Subject-Based Repository Increase access to related material –Benefits to users –Benefits to libraries –Benefits to publishers Achieve economy of scale Ensure long-term availability of materials

Subject-based (Agriculture) Investigating: –Conditions under which publishers willing to deposit digital copies in an external repository –Development of prototype architecture –Development of preservation strategies and goals –Sustainable business plan

Spectrum of Archiving Solutions “Dark” archive Strip formatting to ASCII to simplify tracking and maintenance No access until trigger event Hybrid Lit metadata, dark data “Lit” archive Full access to journal content

Cornell-Project Harvest Sept. 6 Meeting with Publishers Archiving important All publishers intend to keep current and retrospective issues available; want to archive themselves Publishers less concerned than librarians about “artifactual” archiving Some publishers unaware of archival requirements Publishers not enthusiastic about “lit” archives Librarians want trusted third-party archiving (90% of respondents preferred multiple custodians to a single party preserver)

Economic Models for Subject- Based Repository Subscription surcharge Perpetual care endowment Goods for services Business insurance policy model Government support Revenue from broader market distribution and use Value-added services

Next Steps Endorse final version of Attributes of Trusted Repository Develop formal Cornell digital preservation policy Seek support for implementation of math archive Continue research and share work with others
