Preserving Digital Information

Cultural history enthusiasts have asserted the urgent need to protect digital information from imminent loss. This book describes methodology for long-term preservation of all kinds of digital documents. It justifies this methodology using 20th century theory of knowledge communication, and outlines the requirements and architecture for the software needed. The author emphasizes attention to the perspectives and the needs of end users.

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.)

The third edition of Preserving Digital Materials provides a survey of the digital preservation landscape. This book is structured around four questions: 1. Why do we preserve digital materials? 2. What digital materials do we preserve? 3. How do we preserve digital materials? 4. How do we manage digital preservation? This is a concise handbook and reference for a wide range of stakeholders who need to understand how preservation works in the digital world. It notes the increasing importance of the role of new stakeholders and the general public in digital preservation. It can be used as both a textbook for teaching digital preservation and as a guide for the many stakeholders who engage in digital preservation. Its synthesis of current information, research, and perspectives about digital preservation from a wide range of sources across many areas of practice makes it of interest to all who are concerned with digital preservation. It will be of use to preservation administrators and managers, who want a professional reference text, information professionals, who wish to reflect on the issues that digital preservation raises in their professional practice, and students in the field of digital preservation.

Digital information and networks challenge the core practices of libraries, archives, and all organizations with intensive information management needs in many respectsâ€"not only in terms of accommodating digital information and technology, but also through the need to develop new economic and organizational models for managing information. LC21: A Digital Strategy for the Library of Congress discusses these challenges and provides recommendations for moving forward at the Library of Congress, the world's largest library. Topics covered in LC21 include digital collections, digital preservation, digital cataloging (metadata), strategic planning, human resources, and general management and budgetary issues. The book identifies and elaborates upon a clear theme for the Library of Congress that is applicable more generally: the digital age calls for much more collaboration and cooperation than in the past. LC21 demonstrates that information-intensive organizations will have to change in fundamental ways to survive and prosper in the digital age.

In today’s information landscape, there are fewer topics that more urgently demand expansive discourse than digital preservation, which touches on everything from technology to copyright. The Association for Library Collections and Technical Services (ALCTS) steps up to the challenge with this comprehensive overview. Global in scope, it features case studies and contributions that discuss such key issues as the history of digital preservation; digital preservation and information ethics; strategies for getting started, sustaining digitization programs, and performing evaluation; fine-tuning digital preservation workflows, with a look at Digital Streams Matrix for analyzing pathways and tasks; preserving e-books, mobile device data, and other specific types of materials; collaborative efforts in digital preservation, including jargon-free techniques for engaging non-technical colleagues in digital legacy tools and processes; and the copyright, legal, and administrative issues connected with digital preservation. Academic librarians, technical services staff, technologists, and administrators will all benefit from this incisive collection.

There is growing recognition of the need to address the fragility of digital information, on which our society heavily depends for smooth operation in all aspects of daily life. This has been discussed in many books and articles on digital preservation, so why is there a need for yet one more? Because, for the most part, those other publications focus on documents, images and webpages – objects that are normally rendered to be simply displayed by software to a human viewer. Yet there are clearly many more types of digital objects that may need to be preserved, such as databases, scientific data and software itself. David Giaretta, Director of the Alliance for Permanent Access, and his contributors explain why the tools and techniques used for preserving rendered objects are inadequate for all these other types of digital objects, and they provide the concepts, techniques and tools that are needed. The book is structured in three parts. The first part is on theory, i.e., the concepts and techniques that are essential for preserving digitally encoded information. The second part then shows practice, i.e., the use and validation of these tools and techniques. Finally, the third part concludes by addressing how to judge whether money is being well spent, in terms of effectiveness and cost sharing. Various examples of digital objects from many sources are used to explain the tools and techniques presented. The presentation style mainly aims at practitioners in libraries, archives and industry who are either directly responsible for preservation or who need to prepare for audits of their archives. Researchers in digital preservation and developers of preservation tools and techniques will also find valuable practical information here. Researchers creating digitally encoded information of all kinds will also need to be aware of these topics so that they can help to ensure that their data is usable and can be valued by others now and in the future. To further assist the reader, the book is supported by many hours of videos and presentations from the CASPAR project and by a set of open source software.

This book provides a single-volume introduction to the principles, strategies and practices currently applied by librarians and recordkeeping professionals to the critical issue of preservation of digital information. It incorporates practice from both the recordkeeping and the library communities, taking stock of current knowledge about digital preservation and describing recent and current research, to provide a framework for reflecting on the issues that digital preservation raises in professional practice.

A practical guide to the development and operation of digital preservations services for organizations of any size Practical Digital Preservation offers a comprehensive overview of best practice and is aimed at the non-specialist, assuming only a basic understanding of IT. The book provides guidance as to how to implement strategies with minimal time and resources. Digital preservation has become a critical issue for institutions of all sizes but until recently has mostly been the preserve of national archives and libraries with the resources, time and specialist knowledge available to experiment. As the discipline matures and practical tools and information are increasingly available the barriers to entry are falling for smaller organizations which can realistically start to take active steps towards a preservation strategy. However, the sheer volume of technical information now available on the subject is becoming a significant obstacle and a straightforward guide is required to offer clear and practical solutions. Each chapter in Practical Digital Preservation covers the essential building blocks of digital preservation strategy and implementation, leading the reader through the process. International case studies from organizations such as the Wellcome Library, Central Connecticut State University Library in the USA and Gloucestershire Archives in the UK illustrate how real organizations have approached the challenges of digital preservation. Key topics include: • Making the case for digital preservation • Understanding your requirements • Models for implementing a digital preservation service • Selecting and acquiring digital objects • Accessioning and ingesting digital objects • Describing digital objects • Preserving digital objects • Providing access to users • Future trends. Readership: Anyone involved in digital preservation and those wanting to get a better understanding of the process, students studying library and information science (LIS), archives and records management courses and academics getting to grips with practical issues.
