Call to Union / International Association members: please contribute your / your network's digital preservation expertise to our new survey!
In EOSC EDEN, we are interested in how digital preservation professionals across the globe currently work. We are keen to understand the existing frameworks, guidelines and practices for identification, selection and appraisal of data for “long-term” preservation – and what “long term” means in different organisational and professional settings. This is an important area where sharing knowledge can make a meaningful impact as digital preservation continues to grow as a diverse field and community.
