Data Repositories

Sharing your research data via a data repository can support discovery of your data on the web, increase citations and reuse of your data, and help you meet requirements of funding organizations. There are many options available for sharing your data via data repositories.  Learn more about:

Dryad Digital Repository

The NC State University Libraries is an Institutional Member of the Dryad Digital Repository, a platform that makes research data discoverable, freely reusable, and citable. Dryad provides a general-purpose home for a wide diversity of data types. Our institutional membership means that you can deposit datasets in any discipline into Dryad at no cost - the data publishing charges are covered by our membership. 

Key features of Dryad:

  • Flexible about data format, while encouraging the use and further development of research community standards.

  • Fits into the manuscript submission workflow of its partner journals, making data submission easy.

  • Assigns Digital Object Identifiers (DOIs) to data so that researchers can gain professional credit through data citation.

  • Promotes data visibility through usage and download metrics and by allowing content to be indexed, searched and retrieved.

  • Promotes data quality by employing professional curators to ensure the validity of the files and descriptive information.

  • Contents are free to download and re-use under a Creative Commons Zero (CC0) license.

  • Contents are preserved for the long term to guarantee access to contents indefinitely.

  • Open source, standards-compliant technology.

Please contact us at with any questions about Dryad.

Other general data repositories

Below are some examples of additional data repositories that accept data from all disciplines. Be sure to read the repository FAQs and submission instructions to ensure that it is an appropriate match for your research data, to understand the repository’s long-term preservation strategy, and to learn about data deposit fees.

Disciplinary repositories

While general data repositories can be a great choice, we recommend that researchers explore disciplinary repository options to ensure that they choose a repository that will yield the highest impact for their work. It is important to note that some funders and publishers require the use of certain data repositories. Please see the Funding Agency Guidelines for Public Access page for more information about funder mandates and check with any publishers that you may publish with about their requirements.

Re3Data is a tool that can help you find disciplinary data repositories across hundreds of research areas. This vetted source helps answer questions such as who can deposit data and if there are any specific requirements for depositing data.

Below are some examples of well-known discipline-specific repositories. Be sure to read the repository FAQs and submission instructions to ensure that it is an appropriate match for your research data.

  • openICPSR and ICPSR (NC State is a member institution)

    • Data deposited to openICPSR is freely available to anyone and therefore meets sharing mandates that journals or funders may require. openICPSR offers a free Self-Deposit Package and a for-fee Professional Curation Package (plans and pricing).

    • ICPSR offers complete data curation. However, data is only freely available to ICPSR members and therefore may not meet certain sharing mandates. 

      • NC State researchers can have their data professionally curated by ICPSR at no charge, but the data will only be available to other ICPSR members.

      • However, if you choose to pay for ICPSR curation (i.e. with grant funding), your data would be available to both member and non-member institutions. Contact ICPSR ( for a curation estimate, which you can use in your grant application.

General code repositories

Simulation software and other types of code are considered research data. Below are some repositories for this data type.

Questions to consider before you commit to any repository:

  • Is the repository one that your researcher community would normally use to find research data?
  • Can your data be uploaded in a format useful to others in your discipline (and other disciplines)?
  • Can you restrict access to your data as needed (e.g., your data has personal identifiers or is proprietary)?
  • Can the data be cited and found in a unique and persistent way (e.g., with a data citation and a digital object identifier (DOI)?
  • Are preservation actions being taken by the repository to maintain the integrity of your research data (e.g., steps to maintain file integrity, keeping multiple copies, etc.)?
  • How long are your data to be retained in the repository? What will occur at the end of that data retention period?
  • Are your rights as data depositor clear?
  • Are the rights and licenses under which your data can be accessed and used clear? (e.g., through Terms of Use)
  • What will it cost you to have your data deposited in this repository?
