"...let us save what remains: not by vaults and locks which fence them from the public eye and use in consigning them to the waste of time, but by such a multiplication of copies, as shall place them beyond the reach of accident." Thomas Jefferson to Ebenezer Hazard, February 18, 1791.

  • RLG DigNews Interview (2/15/06) with Victoria Reich: Questions you would ask; answers to those questions.
Cites & Insights: Crawford at Large ISSN 1534-0937 “Editors’ interview with Victoria Reich, director, LOCKSS program,” RLG DigiNews 10:1, February 15, 2006.

Want to keep up with LOCKSS (Lots Of Copies Keep Stuff Safe)? (If you care about long-term access to digital journal collections, you should want to maintain awareness of LOCKSS.) Then go read this sevenpage interview—and, frankly, if you’re interested in digital preservation, you should be reading RLG DigiNews on a regular basis anyway. (No full disclosure required: I work for RLG, but have no connection with RLG DigiNews, which is written by staff at Cornell University Library in any case.) It’s free, it’s online, it’s concise, and it has great stuff.

This particular great stuff updates the concepts behind LOCKSS, the state of the LOCKSS alliance (launched in 2005), and the new CLOCKSS initiative (“C” for Controlled), “designed to test the feasibility of a large, community-managed dark archive.”

I won’t attempt to summarize. There’s a lot of information here, tersely presented: the bases for LOCKSS policies and procedures, relationships with publishers, how the LOCKSS polling process works, how much redundancy is needed and desired, the costs of an institutional “LOCKSS box” (one that’s being evaluated is a $3,500 unit with two terabytes of storage—“far less powerful” than a typical desktop or laptop PC, but with loads of storage space and enough computational power to handle LOCKSS requirements), and more. Seriously good stuff.
  • 20 TO WATCH IN 2006: EPS Focus Report: 01/12/2005
  • Electronic Theses and Dissertations (2/3/06) Virginia Tech is developing a proof of concept for “Preservation and harvesting of international Electronic Theses and Dissertations (ETDs) using LOCKSS software and the Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH)”. Partner institutions include: Germany (Humboldt-Universität), Brazil (Pontifícia Universidade Católica do Rio de Janeiro), and South Africa (University of Cape Town). This work further extends the accomplishments of the ASERL LOCKSS ETD project. For further information, please contact Gail McMillan [gailmac at vt dot edu] or Kamini Santhanagopalan [kamini at vt dot edu].
  • CLOCKSS Project (1/23/06) A group of publishers, librarians, and learned societies have launched a community initiative employing the LOCKSS technology to support a large dark archive that serves as a failsafe repository for published scholarly content. Controlled LOCKSS (CLOCKSS), aims to provide assurance to the research community that a disaster, which would prevent the delivery of content, will not obstruct access to journal content. CLOCKSS content or the orphaned content would only become available after a trigger event, such as the material was no longer available from the publisher. In these situations, a joint advisory board, representing societies, publishers and libraries, will begin the process to determine if the content is orphaned and whether it should be made publicly available. The board ensures that content is controlled but that no one person or sector has authority over orphaned digital materials in the system. The initial two-year pilot includes research libraries, commercial and society publishers. During this time, publishers and libraries will continue to work closely to collect and analyze data and develop a proposal for a full-scale archiving model. As part of a longer-term strategy to permanently preserve published work, CLOCKSS will report the findings to the wider community and begin the dialogue about a global infrastructure to ensure preservation of all past, present, and future digital scholarly content.
  • Alaska State Documents (1/23/06) The Alaska State Library and the LOCKSS Alliance have joined together to provide a demonstration project for digital deposit of Alaska State Publications. Alaska State documents are now available for preservation on the LOCKSS system. For more information, please contact Daniel Cornwall [dan_cornwall at eed dot state dot ak dot us].
  • Fugitive U.S. Government Information (1/11/06) A group of LOCKSS Alliance members has joined together on a project to preserve and provide access to fugitive government information via the LOCKSS network. By fugitive we mean government information that was not disseminated through the Federal Depository Library Program. Our first publications for this project are located on the Federation of American Scientists Project on Government Secrecy website. In conjunction with the Director, Steven Aftergood, the LOCKSS team is preserving the valuable government information from this site via the LOCKSS network. You can see the type of information to be preserved at http://fas.org/sgp/ under the "Documents" heading. The following libraries are currently participating in this project: The University of Illinois at Urbana-Champaign, Dartmouth College, Georgia Tech, University of Iowa, Columbia University, University of Kentucky, Rice University, Pennsylvania State University, Stanford University and North Carolina State University. We are currently looking into other titles to preserve and would welcome your input. As always we welcome libraries to join the LOCKSS Alliance and participate in this exciting work. Please contact Elizabeth Cowell [cowell at stanford dot edu] if you have any questions or suggestions.

[edit] 2005

  • Requirements for Digital Preservation Systems: A Bottom-Up Approach The field of digital preservation is being defined by a set of standards developed top-down, starting with an abstract reference model (OAIS) and gradually adding more specific detail. Systems claiming conformance to these standards are entering production use. Work is underway to certify that systems conform to requirements derived from OAIS. We complement these requirements derived top-down by presenting an alternate, bottom-up view of the field. The fundamental goal of these systems is to ensure that the information they contain remains accessible for the long term. We develop a parallel set of requirements based on observations of how existing systems handle this task, and on an analysis of the threats to achieving the goal. On this basis we suggest disclosures that systems should provide as to how they satisfy their goals. http://www.dlib.org/dlib/november05/rosenthal/11rosenthal.html (D-Lib Magazine, November 2005, Volume 11 Number 11)
  • JISC issues call to preserve online journals (11/1/05). Access to entire back runs of electronic journals could be lost to educational institutions when subscriptions are cancelled or when journals cease publication. Because libraries can only lease access to electronic journals, in contrast to their print equivalents, their assets are at risk and valuable online content is in danger of being lost. JISC (Joint Information Systems Committee), in partnership with CURL (Consortium of Research Libraries in the British Isles), today issued a call to librarians and publishers to meet these challenges together. An extended pilot will see the LOCKSS system, devised at Stanford University, deployed in selected libraries in the UK from January 2006. For further information on the LOCKSS Alliance UK partnership, please see http://www.jisc.ac.uk/index.cfm?name=lockss_townmeeting
  • LOCKSS Alliance grows to 50 members (10/27/05) The LOCKSS Alliance has more than 50 academic library members in the United States. "The idea of LOCKSS is to be of, by, and for the library community," Stanford University Librarian Mike Keller said. "It is extremely gratifying to us that the library community has responded so affirmatively in supporting the LOCKSS Alliance." http://www.stanford.edu/dept/news/pr/2005/pr-lockss-110205.html
  • Oxford University Press (10/20/05). Oxford Journals is delighted to announce that it is has begun to preserve its content in Stanford University's LOCKSS Programme.
  • BLOG! Scott Matheson, Yale law librarian is blogging the GPO/LOCKSS pilot project! Scott's blog provides an excellent accounting of Scott's experiences with the LOCKSS system and tracks the GPO/LOCKSS pilot project's progress.
  • A Fresh Look at the Reliability of Long-term Digital Storage (technical report, work in progress 08/05) http://www.arxiv.org/abs/cs.DL/0508130 Many emerging Web services, such as email, photo sharing, and web site archives, need to preserve large amounts of quickly-accessible data indefinitely into the future. In this paper, we make the case that these applications' demands on large scale storage systems over long time horizons require us to re-evaluate traditional storage system designs. We examine threats to long-lived data from an end-to-end perspective, taking into account not just hardware and software faults but also faults due to humans and organizations. We present a simple model of long-term storage failures that helps us reason about the various strategies for addressing these threats in a cost-effective manner. Using this model we show that the most important strategies for increasing the reliability of long-term storage are detecting latent faults quickly, automating fault repair to make it faster and cheaper, and increasing the independence of data replicas.
  • Institute of Physics Announcement (July 27, 2005) Institute of Physics Publishing (IOP) and LOCKSS are pleased to announce that the first of IOP's journal titles have been released for preservation via the LOCKSS system.
  • Preserving web content that's here today and gone tomorrow In response to many requests for a simple demonstration of the capabilities of the LOCKSS system, we published the LOCKSS Winter 2005 Card. The Card contained a movie of the LOCKSS team, an excel spreadsheet, LOCKSS java software, and many other file formats. The card, was available during February and March at http://www.lockss.org/card/2005/february/. It has now disappeared from the web. Fortunately, most of the LOCKSS machines around the world collected and preserved it. The readers at these institutions have perpetual access to this content. This exercise demonstrated a number of important features of the LOCKSS system: Content remains visible after it disappears from the publisher; Access to preserved content is transparent - the Card will be visible at its original URL; The system is format agnostic - the Card includes a wide range of formats (HTML, PDF, Quicktime Movie, Microsoft Excel, gif, JPEG, XML, Java source, Java JAR files)
  • George Mason University's LOCKSS Program Presentation Wally Grotophorst, Associate University Librarian presented the LOCKSS Program to George Washington University librarians on January 11, 2005. This Quicktime presentation is an excellent, entertaining introduction to the Program.
