Increased access to retrodigitised sources does not imply completeness, even when mass digitisation is concerned. Many materials are not, and will never be, digitised. Indeed, digitisation first and foremost means selection. GLAMs select materials to be digitised on the basis of a variety of criteria. These include the preservation of fragile materials, easy access to collection highlights and/or often-used material, the research value of certain collections and academic research agendas. Memory politics, public discourses on the past, and the articulation of a country’s imagined ‘national’ identity are of similar importance while legal, ethical and copyright frame and constraint digitisation strategies, Given the costs involved, the availability of funding, public or private, plays a key role in enabling digitisation projects in the first place (Zaagsma 2013).
