(Dressler, 2010, paraphrased) Emulation is held in the work of Oltmans and Kol to be "more cost-effective for preserving large collections, despite the relatively high initial cots for developing an emulation device." (Dressler, 2010, p.1)

Emulation is contrasted to migration in that migration is applicable to all the objects in a collection respectively, creating high ongoing costs" whereas emulation chaining for the future is likely to detract from this. Emulation can be implemented "at a higher level than the migration approach" therefore, instead of the development of conversion solutions per format "institutions can develop emulation solutions per environment." (Dressler, 2010, p.1) Emulation has not been used widely in preserving over the long-term and there is a need for tests of practicality prior to conclusions being made about the reliability of emulation. Additionally, as noted by Dressler (2010) the selection of emulation strategy ultimately requires "buying into a migration strategy because...
