preservation methods and techniques


Paper-based preservation techniques include preservation photocopying, preservation microfilming, and preservation transfer microfilming. These techniques preserve the content of records, but the artifactual and intrinsic value of the originals cannot be captured in the reproduction.Phased preservation and preservation management look at the preservation needs of a body of materials as a whole, assessing both the physical condition and the value of the materials to determine how to allocate resources to maximize the impact of preservation efforts.Digital preservation techniques include conversion, migration, and emulation.
