Faculty Survey • Electronic archiving important – 76% agree very well – 21% agree somewhat • Libraries should retain paper – 48% very well – 30% somewhat 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 • 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) 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 Subject-Based Repository Building Blocks • • • • • • Cornell Math Collection Project Euclid Zentralblatt Math mirror arXiv.org PROLA /APS EMANI (Electronic Mathematics Archiving Network) • NSF Digital Mathematics Library Planning Grant http://www.library.cornell.edu/preservation/IMLS/ http://www.library.cornell.edu/preservation/tutorial http://www.diglib.org/preserve.htm http://www.dlib.org/dlib/september01/09contents.html www.rlg.org/longterm/attributes01.pdf RLG/OCLC Working Group, Attributes of a Trusted Digital Repository: Meeting the Needs of Research Resources.
