In here are some examples of tools that can be used to share/store data collected. Published a paper and think that people would benefit from looking at the raw data? Want to make that data that has been stored for years useful? Here you’ll find some options on how to do it.
FigShare: Free repository that allows storage of any sort of files (data, code, schematics) and gives each of them a digital object identifier (also keeping track to any changes made), which makes them citable. Also the website has tools to share the data.
Dryad: Repository for data, works in a similar way to Figshare, but Dryad also has a data submission system integrated with a (growing) number of journals, so that paper submissions are synchronized with the data sharing.
