Find Data

Data Repositories and Data Centers

These resources preserve and provide access to data, so the search results are typically only for those items which are held by the repository or data center.

Broad Coverage Repositories and Indexes

A repository where “research outputs are available in citable, shareable and discoverable manner.”

Zenodo builds and operates a simple and innovative service that enables researchers, scientists, EU projects and institutions to share, preserve and showcase multidisciplinary research results (data and publications) that are not part of the existing institutional or subject-based repositories of the research communities.

Government Data Sources

Global Open Data Index
The Global Open Data Index provides the most comprehensive snapshot available of the state of open government data publication across the world.
Data from across goverment organizations and agencies. Includes Agriculture, Climate, Consumer, Ecosystems, Education, Energy, Finance, Health, Local Government, Manufacturing, Maritime, Ocean, Public Safety, and Science & Research.

Data Indexes

These resources provide an index of datasets, usually a compilation from records across a variety of repositories and data centers. The search results will usually be in the form of links to the point of description within a repository or center.

Data Citation Index
Discover research data, including data studies, data sets from a wide range of international data repositories and connect them with the scientific literature to track data citation

Google Data Search
Recently initiated, a work in progress.

Cite Data

When writing a paper or doing a presentation, it’s important to cite the data files used, even if it is data that you have produced.

Citation Elements

A data citation should include at least the following elements. These will depend on the research discipline, source data center/repository, and data format.

  • Responsible party (i.e., investigator, sample collector, creator)
  • Title of dataset
  • Date of publication of the dataset
  • Version, when appropriate
  • Name of data center, repository, and/or publication
  • Analysis software, if required
  • Date accessed
  • Identifier (e.g., DOI or other persistent link)

Tip: If you have a DOI, you can use the CrossCite DOI data citation formatter or the DataCite Citation Formatter to create citations corresponding to a variety of citation styles.

Most data repositories will provide a suggested citation for their datasets. Some will also request citation of related publication(s) along with the data. Follow the most appropriate format while meeting the requirements of the data suppliers.

Guidelines and Examples

Style guides/manuals are beginning to include data as a resource type. However, the Citation Formatters (above) will provide the information in a style that approximates style requirements.

Here are some examples of guidelines:
