In an age where digital content is created and disseminated at an unprecedented pace, the phenomenon of disappearing data has become a critical issue. The rapid turnover of digital information often leads to a total loss of content, creating a form of collective amnesia within our civilization. This digital decay threatens the preservation of cultural, historical, and scientific knowledge, raising concerns about our ability to maintain and access the vast stores of information that define our era.
Digital content on the internet is fleeting, with a high rate of turnover that often results in complete loss. This phenomenon has led to a severe form of collective amnesia, as society may not fully recognize the magnitude of the problem. Stewart Brand, President of The Long Now Foundation, poignantly captures this sentiment, stating that civilization may have become too forgetful to acknowledge the issue adequately.
The disappearance of digital content is not a new occurrence. For example, a significant portion of the 1960 U.S. Census, recorded on UNIVAC II-A tapes, is now inaccessible. Daily, web hosts crash, erasing valuable content in the process. Websites are frequently suspended or blocked due to alleged violations of the host's Terms of Service (TOS), leading to further loss of information. Moreover, countless websites containing unique databases, articles, discussion threads, and links are at risk of vanishing.
One such example is the "Central Europe Review," which boasts an archive of over 2,500 articles and essays on various aspects of Central and Eastern Europe and the Balkans. This is just one of many collections at risk of being lost to the digital void.
The current "digital dark age" can be likened to the period following the destruction of the Library of Alexandria. As information becomes more accessible and abundant, it paradoxically seems to be devalued, leading to a decline in institutional and cultural memory. In the battle between paper and screen, paper has demonstrated remarkable endurance. Newspaper archives dating back to the 1700s are now being digitized, showcasing the resilience and longevity of paper as a medium.
Digital Archival Repositories (DARs), or "Internet Libraries," offer a solution to this problem by providing free access to digital materials replicated across multiple servers, ensuring "safety in redundancy." These libraries contain web pages, television programming, films, e-books, and archives of discussion lists, among other materials. They are invaluable for linguists, journalists, scholars, students, and teachers, as they preserve the social and cultural history of North America at the end of the 20th century. Without these archives, our understanding of our identity and direction would be severely hampered.
The Stanford Archival Vault (SAV) at Stanford University is one such initiative, assigning a numerical handle to every digital "object" in a repository to track and uniquely identify records across multiple repositories. This system also prevents tampering and offers application layers for programmers to develop digital archive software and for users to customize the interface of an archive.
The Internet Archive is a leading digital repository working to prevent the loss of internet and "born-digital" materials. In collaboration with institutions like the Library of Congress and the Smithsonian, it aims to preserve a record of public material.
Data storage is the first phase of digital preservation, but it is not without its challenges. The proliferation of digital content formats necessitates the development of a standard for archiving internet objects. Additionally, as time passes, digital data stored on magnetic media deteriorate and must be migrated to newer media every decade or so. Special emulators are required to decode older data files, and to mitigate the impact of disasters, multiple copies and redundant systems must be maintained.
Furthermore, as "The Economist" highlighted in its Technology Quarterly (September 22nd, 2001), without a "Rosetta Stone" of data formats, future deciphering of stored data might prove to be an insurmountable obstacle.
Ironically, the concept of the paperless office has led to an increase in paper consumption. This paradox underscores the ephemeral nature of digital existence and the challenges faced in preserving our digital heritage.
In conclusion, the affair of vanishing content is a complex issue that requires a multifaceted approach to ensure the longevity and accessibility of digital information. As we continue to generate vast amounts of data, it is imperative that we develop robust systems for preservation to avoid a future where our digital past is irretrievably lost.
