title: An attempt at modeling differentiated storage for digitized collections: finding the balance between storage, costs and preservation of digitized publications
creators: Trudie Stoutjesdijk
abstract: The Koninklijke Bibliotheek (KB) digitizes the national collection of the Netherlands. Digitization leads to multiple versions of a publication: a digital access file, a digital master file, back-ups of the digital versions and the physical original publication. This in turn increases the need for storage capacity quickly. And raises questions like: Should all versions be stored? Do all the versions need to be preserved in order to ensure permanent access, and if so which ones should be preserved and how? Based on the collection care plan and the content strategy a differentiated storage policy is set up in order to establish a relation between the physical object and the digital counterpart(s). This method assigns value to different collection lots and is used to find out how to apply collection care in an efficient way.
