figshare is a repository where you can upload your research outputs to make them citable, shareable and discoverable. You can upload files in any file format, which allows you to disseminate research outputs you may not have in the past, such as figures, datasets, media, papers, posters, presentations and file sets. Any item you make public on figshare will be allocated a DataCite DOI, which means it can be cited. Figshare also records how often items have been viewed or shared, and you can browse or search for the most viewed or shared items. This is a free service.
