A data citation provides attribution to research data sources to allow for easier access to research data within journals and on the Internet. Data citations make allowances for increased acceptance and reward for research data to be considered legitimate, citable contributions to the scholarly record. Citing data also supports the reuse of data and ensures that researchers remain accountable for their data. Data citations provide an opportunity for researchers to track back to the individuals responsible for creating the data so that it can be verified and re-purposed for future study. DataCite is one example of an initiative that has taken the issue of citing data head on by allowing researchers to register their data to receive a DOI and to provide data citation guidelines.
