RIN Publishes To Share or not to Share: Publication and Quality Assurance of Research Data Outputs

The Research Information Network has published To Share or not to Share: Publication and Quality Assurance of Research Data Outputs. The report has a separate Annex file.

This report presents the findings from a study of whether or not researchers do in fact make their research data available to others, and the issues they encounter when doing so. The study is set in a context where the amount of digital data being created and gathered by researchers is increasing rapidly; and there is a growing recognition by researchers, their employers and their funders of the potential value in making new data available for sharing, and in curating them for re-use in the long term.

Digital Preservation of E-Journals in 2008: Urgent Action Revisited Released

Portico and Ithaka have released Digital Preservation of E-Journals in 2008: Urgent Action Revisited.

Here's an excerpt from the announcement:

In September 2005, library directors from 17 universities and colleges met to discuss the current state of electronic journal preservation and endorsed a statement calling for “Urgent Action” to preserve scholarly e-journals. Over two years later in January 2008, in the Portico and Ithaka invited 1,371 library directors of four-year colleges and universities in the United States to respond to a survey examining current perspectives on preservation of e-journals. A strong response has yielded interesting findings that we now share with the community in the hope they will spark useful discussion among library directors, funders, and administrators regarding strategic library priorities.

The survey finds that a large majority of library directors across the spectrum strongly agree or agree that the potential loss of e-journals is unacceptable, and a significant majority believe their own institution has a responsibility to take action to prevent an intolerable loss of the scholarly record. Most larger libraries responding now support one or more e-journal preservation initiatives; however, the majority of respondents from smaller libraries have yet to support any preservation effort and secure permanent access to e-journals for their institutions. The survey shows that this majority is significantly uncertain about their options for e-journal preservation and how urgent is the need to act.

Evaluation of the JISC UK LOCKSS Pilot Report Released

JISC has released Evaluation of the JISC UK LOCKSS Pilot.

Here's an excerpt from the Executive Summary:

This report provides an evaluation of the UK LOCKSS pilot project as it reaches the end of its pilot phase. LOCKSS (Lots Of Copies Keep Stuff Safe) is an international community-based archiving initiative led by Stanford University in the US with over 170 member libraries worldwide, archiving content from over 200 publishers. It is a community-based archiving service operating on open-source software, giving libraries control over their own archived content with the emphasis on low cost and low maintenance.

In March 2006, JISC in partnership with the Consortium of Research Libraries in the British Isles (CURL) funded membership of a collective UK LOCKSS Alliance for 24 selected UK HE libraries. The Digital Curation Centre (DCC) at the department of HATII within the University of Glasgow received funding to set up the UK LOCKSS Technical Support Service to provide technical advice and general support to pilot members and Content Complete Ltd. (CCL) were funded to negotiate with NESLi2 and other publishers to allow LOCKSS-based archiving. The UK LOCKSS pilot is particularly innovative as the first effort to establish a country wide LOCKSS network. The study found that the UK LOCKSS pilot project had achieved its overall aim of setting up a UK LOCKSS Alliance of 30 HE libraries, but that in relation to the detailed aims and objectives there were a number of issues to be addressed if the project was to become self-sustaining at the end of the pilot phase.

Digital Library Federation Spring Forum 2008 Presentations

The Digital Library Federation has released presentations from its Spring Forum 2008.

Here's a selection of the presentations:

ALCTS Preservation and Reformatting Section Publishes Digital Preservation Definition

The Preservation and Reformatting Section of the Association for Library Collections & Technical Services, a division of the American Library Association, has published its formal definition of digital preservation.

Here's an excerpt from the press release:

The definition was developed to promote an understanding of digital preservation within the library community, as well as our allied professions and the user communities we exist to serve. This definition is presented to mark our current understanding of digital preservation and encourage further development of these ideas.

This definition grew out of a conversation held at the Digital Preservation Discussion Group at the ALA Midwinter Meeting in 2007. An ad hoc task force crafted language that was shared with a number of constituencies during the spring and early summer of 2007. The definition was discussed and approved by the PARS Executive Committee during the 2008 Midwinter Meeting in Philadelphia. The ALCTS Board of Directors approved it during Midwinter, and the definition was presented to and accepted by Council as an informational document. The definition is being incorporated into the forthcoming revision of the current ALA Preservation Policy currently being undertaken by PARS.

The working group studied a number of resources to familiarize itself with the critical elements of digital preservation identified by a broad selection of individuals and agencies. These ideas were cast into language that speaks to a wide variety of stakeholders while also being consistent with the core preservation concepts that have developed in the library and archival communities.

The core concepts are presented in a short, medium and long version to accommodate a variety of needs. The long version includes a number of currently accepted best practices but is not intended to be an exhaustive list. As more is learned about implementing digital preservation programs, the definitions should be reviewed and revised on a regular basis.

The definition will be reviewed and updated as needed.

OCLC Announces Digital Archive Service

OCLC has announced the availability of a Digital Archive service.

Here's an excerpt from the press release:

The service provides a secure storage environment for libraries to easily manage and monitor master files and digital originals. The importance of preserving master files grows as a library's digital collections grow. Libraries need a workflow for capturing and managing master files that finds a balance between the acquisition of both digitized and born-digital content while not outpacing a library's capability to manage these large files. . . .

The Digital Archive service is a specially designed system in a controlled operating environment dedicated to the ongoing managed storage of digital content. OCLC has developed specific systems processes and procedures for the service tuned to the management of data for the long term.

From the time content arrives, the Digital Archive systems begin inspecting it to ensure continuity. OCLC systems perform quality checks and record the results in a "health record" for each file. Automated systems revisit these quality checks periodically so libraries receive up-to-date reports on the health of the collection. OCLC provides monthly updated information for all collections on the personal archive report portal.

For users of CONTENTdm, OCLC's digital collection management software for libraries and other cultural heritage institutions, the Digital Archive service is an optional capability integrated with various workflows for building collections. Master files are secured for ingest to the Digital Archive service using the CONTENTdm Acquisition Station, the Connexion digital import capability and the Web Harvesting service.

For users of other content management systems, the Digital Archive service provides a low-overhead mechanism for safely storing master files.

Audiovisual Research Collections and Their Preservation Published

TAPE (Training for Audiovisual Preservation in Europe) has published Audiovisual Research Collections and Their Preservation.

Here's an excerpt from the introduction:

Digital technology has conquered audiovisual production, post-processing, and archiving. Audio has totally become part of the IT world, and video is about to follow the same way. All dedicated audio formats are dead, and soon the same will be the case for video formats. The pace by which dedicated audio and video formats are becoming obsolete is breathtaking. The problem is not so much the survival of the original documents, but the availability of highly specialised replay equipment which disappears from the market soon after a format has been abandoned commercially. Today audiovisual archives associations estimate the time window still open for the transfer of dedicated analogue and digital carriers into digital repositories to be not more than just 20 years.

PREMIS Data Dictionary for Preservation Metadata, Version 2.0 Released

The PREMIS Editorial Committee has released PREMIS Data Dictionary for Preservation Metadata, Version 2.0. A draft XML schema, which will be reviewed for a month before being released in final form, is also available.

Here's an excerpt from the press release:

This document is a revision of Data Dictionary for Preservation Metadata: Final report of the PREMIS Working Group, issued in May 2005. The PREMIS Data Dictionary and its supporting documentation is a comprehensive, practical resource for implementing preservation metadata in digital archiving systems. Preservation metadata is defined as information that preservation repositories need to know to support digital materials over the long term.

This document is a specification that emphasizes metadata that may be implemented in a wide range of repositories, supported by guidelines for creation, management and use, and oriented toward automated workflows. It is technically neutral in that no assumptions are made about preservation technologies, strategies, syntaxes, or metadata storage and management. Members of the PREMIS Editorial Committee revised the original data dictionary based on comments and experience from implementers and potential implementers since its release. The Editorial Committee kept the preservation community informed about issues being discussed, solicited comments on proposed revisions, and consulted outside experts where appropriate. . . .

Major changes in this revision include:

  • Expanded rights metadata
  • More extensive significant properties and preservation level information
  • Mechanism for extensibility for a number of metadata units

Repository Planning Checklist and Guidance Released: Presents Planning Tool for Trusted Electronic Repositories (PLATTER)

DigitalPreservationEurope has released Repository Planning Checklist and Guidance.

Here's an excerpt from the "Executive Summary and Introduction to Platter":

The purpose of this document is to present a tool, the Planning Tool for Trusted Electronic Repositories (PLATTER) which provides a basis for a digital repository to plan the development of its goals, objectives and performance targets over the course of its lifetime in a manner which will contribute to the repository establishing trusted status amongst its stakeholders. PLATTER is not in itself an audit or certification tool but is rather designed to complement existing audit and certification tools by providing a framework which will allow new repositories to incorporate the goal of achieving trust into their planning from an early stage. A repository planned using PLATTER will find itself in a strong position when it subsequently comes to apply one of the existing auditing tools to confirm the adequacy of its procedures for maintaining the long term usability of and access to its material. . . .

The PLATTER process is centred around a group of Strategic Objective Plans (SOPs) through which a repository specifies its current objectives, targets, or key performance indicators in those areas which have been identified as central to the process of establishing trust. In the future, PLATTER can and should be used as the basis for an electronic tool in which repositories will be able to compare their targets with those adopted by other similar (suitably anonymised) repositories. The intention is that the SOPs should be living documents which evolve with the repository, and PLATTER therefore defines a planning cycle through which the SOPs can develop symbiotically with the repository organisation.

ARL Preservation Statistics 2005–06 Published

The Association of Research Libraries has released a PDF version of ARL Preservation Statistics 2005–06, which is freely available.

Here's an excerpt from the "Introduction":

Among the significant developments that took place in research libraries in the 1980s was the emergence of preservation programs as distinct administrative units, separately staffed, funded, and administered. There were 66 such programs reported in 1988, as many as 80 reported in recent years, and 77 in 2005-06.

These rapidly shifting trends have made themselves evident in many categories. Preservation expenditures for ARL’s 111 reporting member libraries were $107,937,836 in 2005-06, which reflects an inflation-adjusted increase of 27% since the survey’s revision in 1996-97.3 Total preservation staff increased to just under 1,800 FTEs in 2005-06, 5.4% more than in 2004-05. Level 1 conservation treatment decreased from 2004-05 levels, while the number of items treated at Levels 2 and 3 increased; total conservation has increased by more than 50,000 volumes in the past year, bringing it higher than it has been in the last four years. . . .

Digitizing bound volumes is gradually emerging as a viable preservation option. In 2005-06, 54 ARL libraries reported more than zero bound volumes digitized. The amount of items digitized varies widely, from one volume at the University of Delaware to 25,121 volumes digitized by the University of Florida.

Sound Directions Project Releases FACET, Preservation Analysis Tool for Audio Works

The Sound Directions: Digital Preservation and Access for Global Audio Heritage Project of Indiana University and Harvard University has released FACET (Field Audio Collection Evaluation Tool), an open-source tool for evaluating preservation issues related to audio works.

Here's an excerpt from the FACET web page:

The Field Audio Collection Evaluation Tool (FACET) is a point-based, open-source software tool that ranks audio field collections based on preservation condition, including the level of deterioration they exhibit and the degree of risk they carry. It assesses the characteristics, preservation problems, and modes of deterioration associated with the following formats: open reel tape (polyester, acetate, paper and PVC bases), analog audio cassettes, DAT (Digital Audio Tape), lacquer discs, aluminum discs, and wire recordings. This tool helps collection managers construct a prioritized list of audio collections by condition and risk, enabling informed selection for preservation. Using FACET provides strong justification for preservation dollars.

Preserving Mixed Analog/Digital AV Archives: PrestoSpace Project Case Study

The Digital Curation Centre has published DCC Case Study—PrestoSpace: Preservation towards Storage and Access. Standardised Practices for Audiovisual Contents in Europe.

Here's the "Executive Summary":

Explicit strategies are needed to manage 'mixed' audio visual (AV) archives that contain both analogue and digital materials. The PrestoSpace Project brings together industry leaders, research institutes, and other stakeholders at a European level, to provide products and services for effective automated preservation and access solutions for diverse AV collections. The Project’s main objective is to develop and promote flexible, integrated and affordable services for AV preservation, restoration, and storage with a view to enabling migration to digital formats in AV archives.

Alternative File Formats for Storing Master Images of Digitisation Projects

Koninklijke Bibliotheek has published Alternative File Formats for Storing Master Images of Digitisation Projects.

Here's an excerpt from the "Management Summary":

The main conclusions of this study are as follows:

Reason 1: Substitution

JPEG 2000 lossless and PNG are the best alternatives for the uncompressed TIFF file format from the perspective of long-term sustainability. When the storage savings (PNG 40%, JPEG 2000 lossless 53%) and the functionality are factored in, the scale tips in favour of JPEG 2000 lossless.

Reason 2: Redigitisation Is Not Desirable

JPEG 2000 and JPEG are the best alternatives for the uncompressed TIFF file format. If no image information may be lost, then JPEG 2000 lossless and PNG are the two recommended options.

Reason 3: Master File is the Access File

JPEG 2000 lossy and JPEG with greater compression are the most suitable formats.

Planets Project Releases White Paper: Representation Information Registries

The Planets (Preservation and Long-term Access through Networked Services) project has released White Paper: Representation Information Registries.

Here's the "Executive Summary":

This document is a report on the state-of-the-art in the field of Representation Information Registries (RIRs). RIRs are widely recognised as a critical component of digital preservation architecture in general, and a number of such registries are being developed as part of the Planets architecture in particular. This document discusses the development of the concept of representation information, and of the use of registries as a means of exposing that information for use by digital preservation services; it describes the RIR implementations which currently exist or are under development globally; it assesses planned and potential future developments in this area; it discusses the role which RIRs play within the Planets project, and concludes with recommendations for future areas of research within Planets and beyond.

NDIIPP's Carl Fleischhauer on Video Formatting and Preservation

The National Digital Information Infrastructure and Preservation Program at the Library of Congress has released Carl Fleischhauer's presentation on "Video Formatting and Preservation" at the Digital Library Federation 2007 Fall Forum.

Here's an excerpt about the presentation from the March 2008 issue of the Library of Congress Digital Preservation Newsletter:

Fleischhauer discussed content wrappers, bitstream encodings, metadata and format profiles for born-digital content. He also spoke about emerging reformatting practices at the Library’s new facility for audiovisual collections and a handful of notable NDIIPP projects.

Sun Centre of Excellence for Libraries to Be Created in Alberta

Sun Microsystems has announced that it is partnering with the University of Alberta Libraries and the Alberta Library to create the Sun Centre of Excellence for Libraries.

Here's an excerpt from the press release:

Sun Microsystems of Canada Inc., the University of Alberta Libraries (UAL) and The Alberta Library (TAL) today announced the creation of a new Sun Centre of Excellence for Libraries (COE). The initiative will enhance and support respective organizational projects, as well as an extensive, province-wide, multi-faceted digital library. As part of the COE the participants intend to provide a seamless search and retrieval experience resulting in unprecedented access to information for students, faculty and the public, as well as creating an enduring preservation environment.

"This initiative will facilitate new levels of access to a tremendous amount of unique information that hasn’t been widely available," said Ernie Ingles, Vice Provost and Chief Librarian, University of Alberta. "It will further our goal to act as a trusted regional repository for digital materials by facilitating approaches to the discovery, storage, and archival preservation of digital resources that will benefit all Canadians." The University of Alberta Libraries, the second largest academic library system in Canada, has more than one million unique digitized pages of content in four major collections to contribute to the new digital library.

Using a range of Sun systems, software and thin client technologies, The Alberta Library (TAL) will integrate current digital collections and electronic information resources from the Lois Hole Campus Alberta Digital Library, an Alberta Government initiative that is providing post-secondary students, faculty and researchers in every corner of the province with access to vast holdings of digital resources. The digital library currently contains more than 4.5 million licensed items, including academic journals, encyclopedias, magazine and newspaper articles, literary criticisms and video clips from 35 post-secondary institutions. The COE will also help TAL improve province-wide access to library catalogues and secure information-sharing. . . .

The COE will support distance learning and research within e-learning environments by providing access to digital collections preserved by Alberta university libraries, archives and museums. It will also yield solutions for long-term archiving of digital resources, and digital rights management. The support and technology provided by Sun will ensure the infrastructure can evolve to meet future needs and continue to support research, collaborative learning and general discovery. . . .

The Centre of Excellence for Libraries is expected to be operational by summer 2008.

Koninklijke Bibliotheek to Preserve Portico E-Journal Archive

Koninklijke Bibliotheek will preserve a dark copy of Portico's archive of digital journals in its e-Depot service.

Here's an excerpt from the press release:

Portico and the Koninklijke Bibliotheek, the National Library of the Netherlands (the KB), are pleased to announce they have reached an agreement for an off-line copy of the Portico archive, which exceeds 6 million articles and 60 million files, to be held for safekeeping by the KB. Through its e-Depot program the KB has demonstrated its role in the vanguard of digital preservation. Placing a Portico-owned copy of the archive, in a secure access- and climate-controlled facility operated by the KB is one component of the replication strategy Portico is implementing to ensure the safety and security of the archive upon which a growing, international community relies. This arrangement also illustrates one way in which organizations internationally recognized for their digital preservation obligations and expertise can cooperate to form a strong, supportive network to safely preserve digital materials.

Here's a description of e-Depot from its home page:

The e-Depot is a digital archiving environment that ensures long-term access to digital objects which would otherwise be threatened by rapidly evolving software and hardware platforms as well as media decay. It is the dedicated archiving environment for the KB’s national electronic deposit collection. In addition, it will include the Dutch web archive and digitised master images. In line with the international nature of information provision, the KB has extended its e-Depot services to publishers worldwide. The e-Depot is supported by sustained research and development efforts geared towards maintaining the integrity of stored digital objects.

Here's a description of Portico from its "About Portico" page:

Portico began as the Electronic-Archiving Initiative launched by JSTOR in 2002 with a grant from The Andrew W. Mellon Foundation to build upon The Foundation's seminal E-Journal Archiving Program. The charge of the Electronic-Archiving Initiative was to build a sustainable electronic-archiving model, and for more than two years, project staff worked on the development of necessary technology and engaged in extensive discussions with publishers and libraries to craft an approach that balances the needs of publishers and libraries while generating sufficient funding for the archive. In 2004, the Electronic-Archiving Initiative became a part of Ithaka Harbors, Inc., a non-profit organization with a mission to accelerate the productive uses of information technologies for the benefit of higher education around the world. Building upon extensive input gathered from commercial and not-for-profit publishers and guidance offered from libraries at a range of small, medium and large academic libraries, an electronic archiving service, known as Portico, was developed. Portico was launched in 2005 with additional support from JSTOR, Ithaka, The Library of Congress, and The Andrew W. Mellon Foundation.

JPEG 2000—A Practical Digital Preservation Standard?

The Digital Preservation Coalition has published JPEG 2000—A Practical Digital Preservation Standard?.

Here's an excerpt from the "Executive Summary":

With JPEG 2000, an application can access and decode only as much of the compressed image as needed to perform the task at hand. This means a viewer, for example, can open a gigapixel image almost instantly by retrieving and decompressing a low resolution, display-sized image from the JPEG 2000 codestream.

JPEG 2000 also improves a user’s ability to interact with an image. The zoom, pan, and rotate operations that users increasingly expect in networked image systems are performed dynamically by accessing and decompressing just those parts of the JPEG 2000 codestream containing the compressed image data for the region of interest. The JPEG 2000 data can be either converted to JPEG and delivered for viewing with a standard image browser or delivered to a native JPEG 2000 viewer using the JPIP client-server protocol, developed to support the JPEG 2000 feature set.

Using a single JPEG 2000 master to satisfy user requests for dynamic viewing reduces storage costs and management overhead by eliminating the need to maintain multiple derivatives in a repository.

Beyond image access and distribution, JPEG 2000 is being used increasingly as a repository and archival image format. What is remarkable is that many repositories are storing “visually lossless” JPEG 2000 files: the compression is lossy and irreversible but the artefacts are not noticeable and do not interfere with the performance of applications. Compared to uncompressed TIFF, visually lossless JPEG 2000 compression can reduce the amount of storage by an order of magnitude or more.

JISC E-Journal Archive Registry Study

JISC has released "Scoping Study for a Registry of Electronic Journals That Indicates Where They Are Archived."

Here's an excerpt from the "Executive Summary":

The research and especially the interviews have confirmed the assumption behind the project that there is a need for more information, and more easily accessible information, about where e-journals are archived. However, what has also emerged strongly is that this issue cannot be considered in isolation, either from the overall context of relationships within the scholarly communication system, nor from other initiatives being undertaken to improve information flows e.g. in relation to the transfer of journal titles between publishers. . . .

Librarians felt that they were most likely to consult a registry in situations where they were considering taking out or renewing a subscription; considering cancellation of a print subscription in favour of an e-only subscription; contemplating relocating or discarding print holdings. The vast majority of potential users of such a registry would be library staff in university and national libraries, though organisations licensing e-journals on behalf of the library community would also be likely to use the registry to check compliance with licence conditions.

One of the key benefits of a registry is perceived to be the exposure of gaps in archive provision. This was identified by all types of stakeholder: librarians would want to be alerted to risks to any of their holdings; publishers who are making provision would like to see their efforts recognised and pressure placed on publishers who are not making satisfactory arrangements; archive organisations would also benefit as that effect fed through to more demand for their services.

The drawbacks to a registry as a solution to the acknowledged information gap were mainly seen as ones of practicality (keeping the information accurate and up to date), trust (especially whether a national solution is appropriate, and conversely whether an international solution is feasible) and sustainability of the funding model. Other solutions were suggested, mainly involving either WorldCat or ERM vendors such as Serials Solutions. The latter were also suggested as a complementary part of a solution involving, but not limited to, a registry.

Preservation in the Age of Large-Scale Digitization: A White Paper

The Council on Library and Information Resources has published Preservation in the Age of Large-Scale Digitization: A White Paper by Oya Rieger.

Here's an excerpt from the "Preface":

This paper examines large-scale initiatives to identify issues that will influence the availability and usability, over time, of the digital books that these projects create. As an introduction, the paper describes four key large-scale projects and their digitization strategies. Issues range from the quality of image capture to the commitment and viability of archiving institutions, as well as those institutions' willingness to collaborate. The paper also attempts to foresee the likely impacts of large-scale digitization on book collections. It offers a set of recommendations for rethinking a preservation strategy. It concludes with a plea for collaboration among cultural institutions. No single library can afford to undertake a project on the scale of Google Book Search; it can, however, collaborate with others to address the common challenges that such large projects pose.

Although this paper covers preservation administration, digital preservation, and digital imaging, it does not attempt to present a comprehensive discussion of any of these distinct specialty areas. Deliberately broad in scope, the paper is designed to be of interest to a wide range of stakeholders. These stakeholders include scholars; staff at institutions that are currently providing content for large-scale digital initiatives, are in a position to do so in the future, or are otherwise influenced by the outcomes of such projects; and leaders of foundations and government agencies that support, or have supported, large digitization projects. The paper recommends that Google and Microsoft, as well as other commercial leaders, also be brought into this conversation.
