The Netherlands National Commission for UNESCO and the European Commission on Preservation and Access have published Preserving the Digital Heritage: Principles and Policies.
Here's an excerpt from the "Preface":
In November 2005, the Netherlands National Commission for UNESCO, in collaboration with the Koninklijke Bibliotheek (National Library of the Netherlands) and UNESCO’s Information Society Division, organized a conference entitled Preserving the Digital Heritage (The Hague, The Netherlands, 4-5 November 2005). It focused on two important issues: the selection of material to be preserved, and the division of tasks and responsibilities between institutions. This publication contains the four speeches given by the keynote speakers, preceded by a synthesis report of the conference.
