The various projects at the Centre for the Study of Manuscript Cultures yield a wealth of research data from both the humanities and the natural sciences. Research data, in this context, can apply to almost any form of data relevant to the study of written artefacts. CSMC strives to make as much data as possible available for open access via the Research Data Repository of Universität Hamburg. The nature of this data ranges from digital images and 3D scans of written artefacts to the raw data and results of material analyses and multispectral imaging. The use of DOI and long-term storage policies ensure an easy navigation of the data objects in the repository. In addition, the repository holds a multitude of CSMC’s various publications. However, some data objects may be either restricted or not accessible due to legal or other concerns.
