20. Recommendations Omnipresent digitisation – identification is more important than ever Digitised objects must be identified, at as many levels as possible (facilitates future use and management of digital libraries) The already existing, standardised identifiers should be used – no need to invent own, proprietary identifiers (facilitates exchange of metadata and linking to objects)

21. Conclusion Traditional identifiers have worked well for the last 40-50 years and have also proved their viability for digitised objects.
