In addition to the Research Repository for research outputs, we now have the Research Data Repository to record and preserve data that has been generated from research projects. This was originally launched to meet EPSRC expectations for research data preservation and discovery. Library services are able to offer secure, long term preservation for data which needs to be kept e.g. because it underpins a publication, and we can help create metadata records relating to preserved data. A permanent identifier is created which can be cited within resulting publications as a link to the underlying data. This is a requirement made by an increasing number of publishers and funders including EPSRC.
