Preserving digital information : report of the Task Force on Archiving of Digital Information by Task Force on Archiving of Digital Information( Book )

12 editions published between 1995 and 1996 in English and held by 327 WorldCat member libraries worldwide

The 21-member Task Force on Archiving of Digital Information was formed in December 1994 and spent a year studying what is needed to make digital libraries stable, accessible, and valid. Their final report is divided into the following sections: (1) "Introduction," which examines the fragility of cultural memory in a digital age and the limits of digital technology; (2) "The Challenge of Archiving Digital Information," a discussion of the obsolescence of certain digital media, migration of digital information to other hardware/software configurations or generations, legal and institutional issues, and the need for deep infrastructure; (3) "Information Objects in the Digital Landscape," which examines the issue of integrity of digital information, and stakeholder interests in that question; (4) "Archival Roles and Responsibilities," about the operating environment, migration strategies, and managing costs and finances; and (5) "Summary and Recommendations." One of the major findings of the study was that a process of certification was needed to create a climate of trust in this field of endeavor. The future needs a sufficient number of people who can be trusted to go to great lengths to store, migrate, and provide access to digital collections. A series of pilot projects and support structures are recommended. Appendices include copies of the charge of the task force and of a detailed analysis of a cost model. (Contains 75 references.)

Into the future : on the preservation of knowledge in the electronic age by Terry Sanders( Visual )

13 editions published between 1997 and 1998 in English and held by 308 WorldCat member libraries worldwide

The film is about the hidden crisis of the digital information age. It discusses if digitally stored information and knowledge will survive into the future. It also explores if information stored in earlier formats, such as reel to reel, magnetic tapes, CD-ROMs, and even earlier versions of Windows will still be accessible
Magnetic tape storage and handling : a guide for libraries and archives by John W. C Van Bogart( Book )

4 editions published in 1995 in English and held by 284 WorldCat member libraries worldwide

This document provides a guide on how to properly store and care for magnetic media to maximize their life expectancies. An introduction compares magnetic media to paper and film and outlines the scope of the report. The second section discusses things that can go wrong with magnetic media. Binder degradation, magnetic particle instabilities, substrate deformation, magnetic tape recorders; and format issues are highlighted in this section. The third and fourth sections cover preventing information loss with multiple tape copies, costs, and how long magnetic media will last. In the fifth section, care and handling, storage conditions and standards, and refreshing of tapes are described for preventing magnetic tape from degrading prematurely. An appendix provides the Ampex Guide to the Care and Handling of Magnetic Tape, an estimation of life expectancies, sources for further reading, resources for transfer and restoration of video and audio tape, and a glossary.

Preservation in the digital world by Paul Conway( Book )

7 editions published in 1996 in English and held by 271 WorldCat member libraries worldwide

This paper seeks to provide an intellectual rationale for maintaining the centrality of preservation concepts and ethics in an increasingly digital information environment; in other words, while some long-held principles of preservation management may no longer apply, many others are still viable in high-tech situations. Libraries are rearranging budgets and raising funds for digital image conversion. They must take steps to ensure long-term access to digital image files. The proposed context for preservation action, or conditions that need to exist as steps are taken, puts a premium on the library's sense of itself as custodian of materials with social value, an organizational structure that allocates resources to preservation, and cooperative effort among institutions. Preservation action should ultimately place priority on the longevity, choice or selectivity, quality, integrity, and accessibility of the images. The paper also offers suggestions for a framework of effective preservation leadership. (Contains 10 figures and 75 references.) (Bew)
New tools for preservation : assessing long-term environmental effects on library and archives collections by James M Reilly( Book )

5 editions published in 1995 in English and held by 261 WorldCat member libraries worldwide

[This publication introduces] time-weighted preservation index (TWPI) technology. TWPI provides a method for measuring and quantifying the effects of temperature and humidity on the preservation quality of storage environments for organic materials. The purpose is to make it easier to manage the preservation of library and archives collections by revealing the long-term effects of storage environments on the deterioration of organic materials. Awareness of environmental effects is the basis for a program of cost-effective improvements. --Publisher description
Avoiding technological quicksand : finding a viable technical foundation for digital preservation : a report to the Council on Library and Information Resources by Jeff Rothenberg( Book )

7 editions published between 1998 and 1999 in English and held by 231 WorldCat member libraries worldwide

There is as yet no viable long-term strategy to ensure that digital information will be readable in the future. Digital documents are vulnerable to loss via the decay and obsolescence of the media on which they are stored, and they become inaccessible and unreadable when the software needed to interpret them, or the hardware on which that software runs, becomes obsolete and is lost. This report explores the technical depth of the problem of long-term digital document preservation, analyzes the inadequacies of a number of ideas that have been proposed as solutions, and elaborates the emulation strategy. The central idea of the emulation strategy is to emulate obsolete systems on future, unknown systems, so that a digital document's original software can be run in the future despite being obsolete. Contents of this report are as follows: (1) Introduction (stating the digital preservation problem and introducing the emulation strategy); (2) The Digital Longevity Problem; (3) Preservation in the Digital Age; (4) The Scope of the Problem; (5) Technical Dimensions of the Problem; (6) The Inadequacy of Most Proposed Approaches; (7) Criteria for an Ideal Solution; (8) The Emulation Solution; (9) Research Required for the Emulation Approach; and (10) Summary.

Why digitize? by Abby Smith Rumsey( Book )

5 editions published in 1999 in English and held by 222 WorldCat member libraries worldwide

This paper is a response to discussions of digitization at meetings of the National Humanities Alliance (nha). Nha asked the Council on Library and Information Resources (clir) to evaluate the experiences of cultural institutions with digitization projects to date and to summarize what has been learned about the advantages and disadvantages of digitizing culturally significant materials. Findings revealed that digitization often raises expectations of benefits, cost reductions, and efficiencies that can be illusory and, if not viewed realistically, have the potential to put at risk the collections and services libraries have provided for decades. One such false expectation--that digital conversion has already or will shortly replace microfilming as the preferred medium for preservation reformatting--could result in irreversible losses of information. This paper defines digital information; identifies weaknesses of digitization as a preservation treatment; discusses the benefits and drawbacks of digital technology for access; and highlights issues institutions must consider in contemplating a digital conversion project.

Digital image collections : issues and practice by Michael Ester( Book )

4 editions published in 1996 in English and held by 219 WorldCat member libraries worldwide

The Commission on Preservation and Access has published a number of reports on the preservation and access implications of scanning text and microfilm. This report focuses on what sets the digitization of visual collections apart from other scanning projects. Projects to digitize visual collections present their own unique set of questions and concerns, as well as issues that overlap with digital capture of text. The report provides basic suggestions about planning digitization projects, practical guidelines for working with images, and some final thoughts about the future systems and infrastructure needed to provide collections of images over the long-term. To use digitization as a tool to provide worthwhile, enduring access to treasured cultural and historical resources, one must become informed, establish guidelines, and proceed in rational, measured steps to assure that such reformatting of visual matter is accomplished as well and as cost-effectively as possible. The paper includes the following sections: (1) Introduction (Digital Images as a Reproduction Medium and Of Letters, Lines and Images: Reproductions in Print Publications); (2) The Original Object and Its Reproduction; (3) a Framework for Assessing Image Quality; (4) Color Matching for Image Collections (Color Management, Transformation and Image Output and Controlling Images in Distribution Environments); (5) Documentation and the Integration of Image and Text (Production and Management Documentation); (6) Building Image Collections; and (7) Image Access and User Environments (Rights To Image Collections, Electronic Publications and Use of Visual Materials, and How Will Collections of Digital Images Be Created?).

A hybrid systems approach to preservation of printed materials by Don Willis( Book )

6 editions published in 1992 in English and held by 215 WorldCat member libraries worldwide

Intended to stimulate thought and discussion, this report compares micrographics and digital imaging as tools for the preservation of printed materials. The topics covered include: (1) the advantages and disadvantages of each technology; (2) trade-offs involved in selecting one technology over another; (3) benefits of using a hybrid approach; (4) whether the page should be captured first to film and converted to digital, captured digitally and converted to film, or whether the two can be done simultaneously; (5) the options for converting from film to digital and back again; (6) cost factors, including how to maximize image quality while minimizing cost; (7) the roles of ascii text and ocr (optical character recognition); (8) resolution issues for each technology; and (9) standards. It is concluded that microfilm will preserve printed materials very well and that the equipment needed to transfer this material to other media will be available for centuries; and that optical storage can be considered on a selective basis provided there is a plan to recopy the media prior to any substantial degradation and before the technology becomes obsolete. It is recommended that, for the longer term, practitioners should immediately begin planning for, and designing, the hybrid archival preservation system of the future. It is suggested that such a system could combine the strengths of micrographics with digital imaging, which contributes access, distribution, and transmission strengths. A discussion of digital imaging resolution, a summary of alternative storage possibilities, data storage costs in a variety of formats, a comparison of film and digital costs, and a list of resources for equipment performance standards are appended. Examples of images copied using different media are also provided. (Krn)

Mass deacidification : an update on possibilities and limitations by Henk J Porck( Book )

4 editions published in 1996 in English and held by 189 WorldCat member libraries worldwide

This report provides an update of the possibilities and limitations of currently available mass deacidification methods, focusing on the major developments in research and application of the main operational systems. This study is intended primarily to support the development of a well-considered preservation policy by librarians and archivists, with a focus on the practical implications of mass deacidification rather than the technical details of the deacidification process. The study provides a brief history of the development of the technical process, a condensed description of the treatment principle, an overview of available research and test results, indicating the main advantages and disadvantages of the process, and an inventory of actual applications for five mass deacidification systems: (1) "Battelle"; (2) "Bookkeeper"; (3) "dez"; (4) "fmc"; and (5) "Wei T'O." Several other initiatives are also described, involving large-scale rather than mass treatment technologies, and essentially combining deacidification with strengthening of paper. The main findings are discussed within the framework of a critical evaluation of the current possibilities and limitations of mass deacidification in general. A list of contacts is provided.

The setup phase of Project Open Book : a report to the Commission on Preservation and Access on the status of an effort to convert microfilm to digital imagery by Paul Conway( Book )

7 editions published in 1994 in English and held by 166 WorldCat member libraries worldwide

Digital image quality, indexing structures, and production workflow were the three central issues examined during the second phase--the set-up phase--of Project Open Book, a major effort by Yale University Library to explore the usefulness of digital technologies for preserving and improving access to deteriorating documents. This report outlines the incremental progress made during the set-up phase and describes the results of Yale's investigation into the administrative requirements for high-volume production conversion. In 1993, Yale set up and evaluated components of an in-house production-conversion facility, converted and indexed 100 volumes in a test run, and prepared for the conversion from preservation microfilm of the next 3,000 volumes of a projected 10,000-volume digital library. A production workflow plan was developed that stressed the importance of working with vendors, training staff, and broad administrative support. The set-up phase focused intensely on process quality, efficient ways to use existing database technology, and specific steps in the conversion process. The production-conversion phase will define requirements for conversion and validate the conversion model. (Contains 11 references.) (Sld)
The Cornell/Xerox/Commission on Preservation and Access Joint study in digital preservation : report, phase 1, January 1990-December 1991 : digital capture, paper facsimiles and network access by Anne R Kenney( Book )

6 editions published in 1992 in English and held by 153 WorldCat member libraries worldwide

The primary emphasis of this study of the use of digital technology to preserve library materials was the capture of brittle books as digital images and the production of printed paper facsimiles. Of equal interest, however, was the role of digital technology in providing access to library resources, and preliminary work in this area has also been accomplished. Based on extensive experimentation with one digital scanning system, the study reached five principal conclusions: (1) digital image technology provides an alternative--of comparable quality and lower cost--to photocopying for preserving deteriorating library materials; (2) subject to the resolution of certain problems, digital scanning technology offers a cost effective adjunct or alternative to microfilm preservation; (3) digital technology has the potential to enhance access to library materials; (4) through the implementation of document control structures, digital technology offers a means to facilitate access and to provide links between the library catalog and the material itself; and (5) the infrastructure developed for library preservation and access activities supports other applications in the electronic dissemination of information. This report is divided into three major sections: a description of the products developed to reach project goals; a review of the process of applying digital scanning technology to the preservation of and access to library materials; and a discussion of the findings. Four appendixes offer information on the comparative quality of paper and facsimile copies; a description of a cost study; assumptions of the cost study, including equipment, labor and materials costs; and a scanning diagram.

SGML as a framework for digital preservation and access by James Coleman( Book )

4 editions published in 1997 in English and held by 151 WorldCat member libraries worldwide

This report explores the suitability of Standard Generalized Markup Language (sgml) as a framework for building, managing, and providing access to digital libraries, with special emphasis on preservation and access issues. Sgml is an international standard (iso 8879) designed to promote text interchange. It is used to define markup languages, which can then encode the logical structure and content of any so-defined document. The connection between sgml and the traditional concerns of preservation and access may not be immediately apparent, but the use of descriptive markup tools such as sgml is crucial to the quality and long-term accessibility of digitized materials. Beginning with a general exploration of digital formats for preservation and access, the report provides a staged technical tutorial on the features and uses of sgml. The tutorial covers sgml and related standards, sgml Document Type Definitions in current use, and related projects now under development. A tiered metadata model is described that could incorporate sgml along with other standards to facilitate discovery and retrieval of digital documents. Endnotes and a bibliography provide further resources. Appendices include: a discussion of practical concerns related to the uses of sgml in conversion and authoring projects, descriptions of markup format and sgml tools, and a vendor's look at cost metrics. The report concludes that sgml meets current preservation and access requirements for digital libraries and that sgml solves the widest range of archival database problems today: sgml is a standard; it is non-proprietary and platform-independent; and it allows rich, full access to content-based digital documents. The sgml framework should be seriously considered when planning digital library projects. (Author)
The organizational phase of Project Open Book : a report to the Commission on Preservation and Access by Donald J Waters( Book )

4 editions published in 1992 in English and held by 149 WorldCat member libraries worldwide

The Yale University Library is now organized to move ahead with Project Open Book, the conversion of 10,000 books from microfilm to digital imagery. In the first phase of the Project--the organizational phase--a Steering Committee was established that included several faculty members, and a project team was created. In addition, Yale conducted a formal bid process and selected the Xerox Corporation to serve as its principal partner in the project. Xerox has identified for Yale the required equipment, software, and services to complete the project, as well as their costs, and has proposed a three-phase implementation plan. The implementation will ultimately result in a conversion subsystem, browsing stations distributed on the campus network within the Yale Library, a subsystem for storing 10,000 books in digital form, and network access to high-quality image printers. The process leading to the selection of the vendor helped isolate areas of risk and uncertainty as well as key issues to be addressed during the life of the project. The Yale Library is now prepared to select the material for conversion to digital image form and to seek funding, initially for the first phase, and then for the entire project. This report reviews the purpose and scope of the project, outlines the steps taken in the first (organization) phase, and presents a summary of the results to date. (Author/KRN)
Isoperms : an environmental management tool by Donald K Sebera( Book )

3 editions published in 1994 in English and held by 149 WorldCat member libraries worldwide

A quantitative tool, the isoperm method, is described; it quantifies the effect of environmental factors of temperature (t) and percent relative humidity (%rh) on the anticipated useful life expectancy of paper-based collections. The isoperm method provides answers to questions of the expected lifetime of the collection under various temperature and relative humidity conditions, as well as a way to demonstrate the effects in quantifiable terms. The method is based on paper-strength loss associated with the chemical reactions of cellulose hydrolysis and oxidation. Relative, rather than absolute, rates of deterioration and paper permanence are employed. The deterioration-rate ratio can be controlled through changes in temperature and percent relative humidity, but it is not possible to change nonenvironmental factors, such as fiber type and so forth. The isoperm method is a step toward using quantitative analysis techniques and models to help make preservation-management decisions. Seven figures illustrate the discussion. (Contains 8 references.)
