Evidence for Informed Preservation Planning and Advocacy: A Synoptic View

We argue the need to demonstrate the value of preservation services to institutions, the public and funders, because it matters conceptually and needs to be supported and validated. To address this imperative, improved and focused data capture and its use by collection managers is advocated as the necessary first step towards the development of an evidence-based culture for preservation services and synoptic decision-making, where evidence enables us to optimise the outcome of planning. To do so, we need tools that enable us to evaluate diverse preservation scenarios. We demonstrate the potential of emerging cross-disciplinary tools and protocols developed in the recent years such as attitude surveys, computational modelling and demographic modelling. These offer evidence that informs prospective preservation planning and, importantly, provides a credible evidence base for advocacy. These possibilities are discussed within the wider context of well-established preservation planning protocols that have shaped collection management for three decades, broadly characterised as retrospective.
