The WashU Digital Research Materials Repository is a subset of the OpenScholarship institutional repository. Your primary research materials will be archived and accessible for future researchers to reuse, which increases your research impact. If your grant funder or publisher includes data sharing and archiving requirements, curating your data with the WU Libraries will fulfill this requirement. Curating your research materials with the library will involve enriching your data beyond the standard storage and backup techniques. Improve the discoverability and cite-ability of your research materials through the assignment of a DOI and the dissemination of your research to international linked data platforms.
