In the last decade there have been many initiatives and projects that have dealt with open educational resources with the goal of making education more available and also of improving formal educational practices. The Erasmus+ project Digital Education for Crisis Situations: Times When There Is No Alternative is such an initiative and one of its planned intellectual outputs is to produce a new open educational resource on the preservation of analogue and digital materials. Planning and creating an open educational resource on preservation needs to be based on an understanding of the content that comprises the complex field of preservation. This also provides the basis for conducting research on the available open educational resources in this field. This article aims to provide an overview of the available open educational resources on preservation through an investigation of open educational resource platforms, finding open educational resources on preservation, and analysing them according to the theoretical background on preservation. This provides an understanding of what kinds of open educational resources exist in the field of preservation and also informs the way a new open educational resource should be created.
