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 United States Congress in December 2000 appropriated funds to the Library of Congress (LC) to spearhead an effort to develop a national strategy for the preservation of digital information. LC staff scheduled a series of conversations with representatives from the technology, business, entertainment, academic, legal, archival, and library communities, and asked the Council on Library and Information Resources to commission background papers for these sessions and to summarize the meetings. The resulting papers, along with an integrative essay by Amy Friedlander, are presented in this document. Contents include: "Summary of Findings" (Amy Friedlander); "Preserving Digital Periodicals" (Dale Flecker); "E-Books and the Challenge of Preservation" (Frank Romano); "Archiving the World Wide Web" (Peter Lyman); "Preservation of Digitally Recorded Sound" (Samuel Brylawski); "Understanding the Preservation Challenge of Digital Television" (Mary Ide, Dave MacCarn, Thom Shepard, and Leah Weisse); and "Digital Video Archives: Managing through Metadata" (Howard D. Wactlar and Michael G. Christel). (AEF).

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.

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.

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.
