Description: Between the two fundamental digital preservation strategies, migration has been strongly favored. Recent developments in emulation frameworks make it possible to deliver emulations to readers via the Web in ways that make them appear as normal components of Web pages. This removes what was the major barrier to deployment of emulation as a preservation strategy. Barriers remain, the two most important are that the tools for creating preserved system images are inadequate, and that the legal basis for delivering emulations is unclear, and where it is clear it is highly restrictive. Both of these raise the cost of building and providing access to a substantial, well curated collection of emulated digital artefacts beyond reach. This book advocates that if the above mentioned barriers can be addressed, emulation will play a much greater role in digital preservation in the coming years. It will provide access to artefacts that migration cannot, and even assist in migration where necessary by allowing the original software to perform it. The evolution of digital artefacts means that current artefacts are more difficult and expensive to collect and preserve than those from the past, and less suitable for migration. This trend is expected to continue. Emulation is ...
