A Digital Object Identifier (DOI) is assigned to each international database every time there is an update to the data. The new DOI will resolve to this page containing a log of previous editions since the allocation of its first DOI. The DOI system supports resource discovery and simplifies citation for users of data collections. Data producers benefit directly through increased visibility of their work.
