      The Digital Curation Centre has released Preservation and Curation in Institutional Repositories.

      Here's an excerpt from the announcement:

      The DCC has produced a report that provides a snapshot of the state of the art of preservation and curation in an institutional repository context in early 2010, noting areas of recent and current research and development. It should be of interest principally to institutional repository managers and others concerned with the strategic planning for these services. The report begins with a brief introduction to preservation and curation, followed in chapter 3 by a summary of the current provision for these activities in EPrints, DSpace and Fedora. Some repository models and architectures relevant to preservation and curation are presented in chapter 4 and chapter 5 respectively, while a selection of preservation planning tools of possible use in a repository context are described in chapter 6. Pertinent developments in metadata are reviewed in chapter 7, while tools for working with such metadata are presented in chapter 8. Technologies that assist in performing emulation, reverse engineering and migration are described in chapter 9. The issue of identifiers for repository materials is tackled in chapter 10. A selection of guidelines and tools for auditing curatorial aspects of institutional repositories is presented in chapter 11, and a selection of tools for calculating the costs and benefits of curation is presented in chapter 12. Finally, some conclusions are drawn in chapter 13.

        Web Archiving

        Posted in Digital Curation & Digital Preservation on March 21st, 2010

        The Digital Curation Centre has released Web Archiving.

        Here's an excerpt from the announcement:

        The DCC has produced a report that provides a snapshot of the state of the art of Web archiving in early 2010, noting areas of contemporaneous research and development. It should be of interest to individuals and organisations concerned about the longevity of the Web resources to which they contribute or refer, and who wish to consider the issues and options in a broad context. The report begins by reviewing in more detail the motivations that lie behind Web archiving, both from an organisational and a research perspective. The most common challenges faced by Web archivists are discussed in section 3. The following two sections examine Web archiving at extremes of scale, with section 4 dealing with full-domain harvesting and the building of large-scale collections, and section 5 dealing with the ad hoc archiving of individual resources and small-scale collections. The challenges associated with particular types of difficult content are summarised in section 6, while methods for integrating archived material with the live Web are reviewed in section 7. Finally, some conclusions are drawn in section 8.

          Sustainable Economics for a Digital Planet: Ensuring Long-term Access to Digital Information

          Posted in Digital Curation & Digital Preservation on March 2nd, 2010

          The Blue Ribbon Task Force on Sustainable Digital Preservation and Access has released Sustainable Economics for a Digital Planet: Ensuring Long-term Access to Digital Information.

          Here's an excerpt from the press release:

          While much has been written on the digital preservation issue as a technical challenge, the Blue Ribbon Task Force report focuses on the economic aspect; i.e. how stewards of valuable, digitally-based information can pay for preservation over the longer term. The report provides general principles and actions to support long-term economic sustainability; context-specific recommendations tailored to specific scenarios analyzed in the report; and an agenda for priority actions and next steps, organized according to the type of decision maker best suited to carry that action forward. Moreover, the report is intended to serve as a foundation for further study in this critical area. . . .

          Value, Incentives, and Roles & Responsibilities

          The report of the Blue Ribbon Task Force focuses on four distinct scenarios, each having ever-increasing amounts of preservation-worthy digital assets in which there is a public interest in long-term preservation: scholarly discourse, research data, commercially-owned cultural content (such as digital movies and music), and collectively-produced Web content (such as blogs).

          "Valuable digital information spans the spectrum from official e-documents to some YouTube videos. No one economic model will cost-effectively support them all, but all require cost-effective economic models," said Berman, who was director of the San Diego Supercomputer Center at the University of California, San Diego, before joining Rensselaer last year.

          The report categorizes the economics of digital preservation into three "necessary conditions" closely aligned with the needs of stakeholders: recognizing the value of data and selecting materials for longer-term preservation; providing incentives for decision makers to preserve data directly or provide preservation services for others; and articulating the roles and responsibilities among those involved in the preservation process. The report further aligns those conditions with the basic economic principle of supply and demand, and warns that without well-articulated demand for access to preserved digital assets, there will be no supply of preservation services.

          "Addressing the issues of value, incentives, and roles and responsibilities helps us understand who benefits from long-term access to digital materials, who should be responsible for preservation, and who should pay for it," said Brian Lavoie, research scientist at OCLC and Task Force co-chair. "Neglecting to account for any of these conditions significantly reduces the prospects of achieving sustainable digital preservation activities over the long run."

          Task Force Recommendations The Blue Ribbon panel report cites several specific recommendations for decision makers and stakeholders to consider as they seek economically sustainable preservation practices for digital information. While the report covers these recommendations in detail, below is a summary listing key areas of priority for near-term action:

          Organizational Action

          • develop public-private partnerships, similar to ones formed by the Library of Congress
          • ensure that organizations have access to skilled personnel, from domain experts to legal and business specialists
          • create and sustain secure chains of stewardship between organizations over the long term
          • achieve economies of scale and scope wherever possible

          Technical Action

          • build capacity to support stewardship in all areas
          • lower the costs of preservation overall
          • determine the optimal level of technical curation needed to create a flexible strategy for all types of digital material

          Public Policy Action

          • modify copyright laws to enable digital preservation
          • create incentives and requirements for private entities to preserve on behalf of the public (financial incentives, handoff requirements)
          • sponsor public-private partnerships
          • clarify rights issues associated with Web-based materials

          Education and Public Outreach Action

          • promote education and training for 21st century digital preservation (domain-specific skills, curatorial best practices, core competencies in relevant science, technology, engineering, and mathematics knowledge)
          • raise awareness of the urgency to take timely preservation actions

          The report concluded that sustainable preservation strategies are not built all at once, nor are they static.

          "The environment in which digital preservation takes place can be very dynamic," said OCLC's Brian Lavoie. "Priorities change, policies change, stakeholders change. A key element of a robust sustainability strategy is to anticipate the effect of these changes and take steps to minimize the risk that long-term preservation goals will be impacted by short-term disruptions in resources, incentives, and other economic factors. If we can do this, we will have gone a long way toward ensuring that society's valuable digital content does indeed survive."

          About the Blue Ribbon Task Force on Sustainable Digital Preservation and Access The Blue Ribbon Task Force on Sustainable Digital Preservation and Access was launched in late 2007 by the National Science Foundation and The Andrew W. Mellon Foundation, in partnership with the Library of Congress, the Joint Information Systems Committee of the United Kingdom, the Council on Library and Information Resources, and the National Archives and Records Administration. The Task Force was commissioned to explore the economic sustainability challenge of digital preservation and access. An Interim report discussing the economic context for preservation, Sustaining the Digital Investment: Issues and Challenges of Economically Sustainable Digital Preservation, is available at the Task Force website. Please visit the website for more information about the Task Force and its upcoming symposium, called A National Conversation on the Economic Sustainability of Digital Information, to take place April 1, 2010 in Washington D.C. A similar symposium will be held in the United Kingdom on May 6, 2010, at the Wellcome Collection Conference Centre, in London. Space is limited so early registration is advised. More information is available online.

            A Guide to Distributed Digital Preservation

            Posted in Digital Curation & Digital Preservation on February 24th, 2010

            The MetaArchive Cooperative has released A Guide to Distributed Digital Preservation.

            Here's an excerpt from the announcement:

            This volume is devoted to the broad topic of distributed digital preservation, a still-emerging field of practice for the cultural memory arena. Replication and distribution hold out the promise of indefinite preservation of materials without degradation, but establishing effective organizational and technical processes to enable this form of digital preservation is daunting. Institutions need practical examples of how this task can be accomplished in manageable, low-cost ways.

            This guide is written with a broad audience in mind that includes librarians, archivists, scholars, curators, technologists, lawyers, and administrators. Readers may use this guide to gain both a philosophical and practical understanding of the emerging field of distributed digital preservation, including how to establish or join a network.

                    Center for Research Libraries Certifies Portico as Trustworthy Digital Repository

                    Posted in Digital Curation & Digital Preservation, Digital Repositories on January 26th, 2010

                    The Center for Research Libraries has certified Portico as a trustworthy digital repository.

                    Here's an excerpt from the announcement:

                    This month the Center for Research Libraries (CRL) announced the completion of an audit of the Portico digital repository and its certification as a trustworthy digital repository. Portico is the first digital preservation service to undergo this independent audit and the only service to be certified at this time.. . .

                    The nine-month audit process was an extremely positive and valuable one for Portico. It confirmed that the majority of our practices conform to the Trustworthy Repositories Audit and Certification Checklist (TRAC) and other metrics developed by CRL through its analyses of digital repositories. It also identified for us several areas for continued improvement as well as ways in which we can enhance the service for CRL member libraries as well as others. We look forward to continuing to report to CRL on these issues in the years ahead to ensure we continue to meet certification requirements and the expectations of CRL libraries, our other partner libraries, and our participating publishers.

                    We invite you to review the background information about CRL's Certification and Assessment of Digital Repositories Program ( as well as the public audit report on Portico published by the CRL Certification Advisory Panel (

                      Data Dimensions: Disciplinary Differences in Research Data Sharing, Reuse and Long Term Viability

                      Posted in Data Curation, Open Data, and Research Data Management, Digital Curation & Digital Preservation on January 24th, 2010

                      The Digital Curation Centre has released Data Dimensions: Disciplinary Differences in Research Data Sharing, Reuse and Long Term Viability: A Comparative Review Based on Sixteen Case Studies.

                      Here's an excerpt:

                      This synthesis study, commissioned by the Digital Curation Centre from Key Perspectives Ltd, forms a major output from the DCC SCARP Project, which investigated attitudes and approaches to data deposit, sharing and reuse, curation and preservation, over a range of research fields in differing disciplines. The aim was to investigate research practitioners’ perspectives and practices in caring for their research data, and the methods and tools they use to that end. Objectives included identification and promotion of ‘good practice’ in the selected research domains, as expressed in DCC tools and resources. The approach combined case study methods with a survey of the literature relevant to digital curation in the selected fields. . . .

                      This synthesis report (which drew on the SCARP case studies plus a number of others, identified in the Appendix), identifies factors that help understand how curation practices in research groups differ in disciplinary terms. This provides a backdrop to different digital curation approaches. However the case studies illustrate that "the discipline" is too broad a level to understand data curation practices or requirements. The diversity of data types, working methods, curation practices and content skills found even within specialised domains means that requirements should be defined at this or even a finer-grained level, such as the research group.

                        Report and Recommendations from the Scholarly Publishing Roundtable

                        Posted in Digital Curation & Digital Preservation, Open Access, Publishing, Scholarly Communication on January 14th, 2010

                        The Scholarly Publishing Roundtable has released the Report and Recommendations from the Scholarly Publishing Roundtable.

                        Here's an excerpt from the press release:

                        An expert panel of librarians, library scientists, publishers, and university academic leaders today called on federal agencies that fund research to develop and implement policies that ensure free public access to the results of the research they fund "as soon as possible after those results have been published in a peer-reviewed journal."

                        The Scholarly Publishing Roundtable was convened last summer by the U.S. House Committee on Science and Technology, in collaboration with the White House Office of Science and Technology Policy (OSTP). Policymakers asked the group to examine the current state of scholarly publishing and seek consensus recommendations for expanding public access to scholarly journal articles.

                        The various communities represented in the Roundtable have been working to develop recommendations that would improve public access without curtailing the ability of the scientific publishing industry to publish peer- reviewed scientific articles.

                        The Roundtable’s recommendations, endorsed in full by the overwhelming majority of the panel (12 out of 14 members), "seek to balance the need for and potential of increased access to scholarly articles with the need to preserve the essential functions of the scholarly publishing enterprise," according to the report. . . .

                        The Roundtable identified a set of principles viewed as essential to a robust scholarly publishing system, including the need to preserve peer review, the necessity of adaptable publishing business models, the benefits of broader public access, the importance of archiving, and the interoperability of online content.

                        In addition, the group affirmed the high value of the "version of record" for published articles and of all stakeholders' contributions to sustaining the best possible system of scholarly publishing during a time of tremendous change and innovation.

                        To implement its core recommendation for public access, the Roundtable recommended the following:

                        1. Agencies should work in full and open consultation with all stakeholders, as well as with OSTP, to develop their public access policies. Agencies should establish specific embargo periods between publication and public access.
                        2. Policies should be guided by the need to foster interoperability.
                        3. Every effort should be made to have the Version of Record as the version to which free access is provided.
                        4. Government agencies should extend the reach of their public access policies through voluntary collaborations with non-governmental stakeholders.
                        5. Policies should foster innovation in the research and educational use of scholarly publications.
                        6. Government public access policies should address the need to resolve the challenges of long-term digital preservation.
                        7. OSTP should establish a public access advisory committee to facilitate communication among government and nongovernment stakeholders.
