The goal of digital preservation is to ensure long-term access to digitally stored information. In this paper, we present a survey of techniques used in digital preservation. We also introduce representative digital preservation projects and case studies that provide insight into the advantages and disadvantages of different preservation strategies. Finally, the pros and cons of current strateg...

As we develop our ability to preserve digital collections through techniques such as migration and emulation, the decision process of what action to take and when to take it becomes increasingly complex. Cost is a crucial factor to consider but the financial implications of preservation planning decisions are not typically well understood. At a strategic level, there are also significant challe...

Executive Summary On 9 to 11 April 2003, ERPANET hosted an expert workshop on the long-term preservation of databases. The workshop took place at the Swiss Federal Archives in Berne and assembled 65 participants from 16 countries all over Europe and the USA. As the third in a series of six expert meetings, the workshop aimed at gathering knowledge about the state-of-the-art in database preserva...

OBJECTIVE The aim of the present study was to evaluate the long-term hearing during "wait and scan" management of vestibular schwannomas. SUBJECTS During a 33-year period, from 1976 to 2008, 1,144 patients with vestibular schwannoma were allocated to observation by the wait and scan policy, with annual magnetic resonance imaging and audiologic examination. Two complete pure-tone and speech di...

In this paper we describe the services that are offered by CERN [3] for Long Term preservation of High Energy Physics (HEP) data, with the Large Hadron Collider (LHC) as a key use case. Data preservation is a strategic goal for European High Energy Physics (HEP) [9], as well as for the HEP community worldwide and we position our work in this global content. Specifically, we target the preservat...

Viability of Bordetella pertussis was preserved when glycerol broth suspensions were quick frozen and stored at -70 C for as long as 45 months.

Much of the new information created today is in digital form and needs to be archived that way. Older information, mostly on paper, is in danger of becoming unreadable – or inaccessible and needs to be converted to digital form. In both cases, it is imperative that the digital files be usable even in a distant future, either because they are relevant to the functioning of a company, organizatio...

This paper discussed the characteristics of the self-built digital resources and the requirement for long-term preservation. A backup system for self-built digital resources has been proposed based on the software and hardware features of the resources. Furthermore, simple analysis has been carried out on the proposed system. Index Terms – self-built digital resource, backup system, long-term p...

Authors have always been looking for new and innovative ways of aesthetical expression and they have been quick to take advantage of the new possibilities, offered by the World Wide Web and the Internet. Today, there is a respectable community – in terms of size and quality – of “digital poets”, who publish their texts in the internet and whose literature above all shares one mutual feature: a ...
