This site contains documentation for the Dryad repository and associated projects. To access the Dryad repository, go to For the latest news on Dryad and data archiving, check out Dryad News and Views. Please contact Dryad staff with any inquiries.

Dryad is an international repository of data underlying peer-reviewed articles in the basic and applied biosciences. Dryad allows investigators to validate published findings, explore new analysis methodologies, repurpose the data for research questions unanticipated by the original authors, and perform synthetic studies such as formal meta-analyses. All data files in Dryad are available for download and reuse, except those that are under a temporary embargo period, as permitted by editors of the relevant journals.

Dryad aims to provide one-stop data deposition upon publication by interfacing with specialized repositories which are already required for publication (such as GenBank and TreeBASE). However, for many publications, these repositories do not capture the whole data package. As a result, many important datasets are not being preserved and are no longer available, or usable, at the time that they are sought by later investigators.

To staunch this loss, Dryad serves as a repository for tables, spreadsheets, flatfiles, and all other kinds of published data that do not currently have a home. A major design consideration with these data is to avoid placing an undue burden of metadata generation on individual researchers while at the same time capturing sufficient metadata to enable data discovery and reuse. A special section of the repository named Dryad Lab hosts datasets of particular educational value for use in undergraduate and graduate training.

Any journal or publisher that wishes to encourage data archiving may refer authors to Dryad. Dryad welcomes data submissions related to any published, or accepted, article in the biosciences.

Journals and publishers can facilitate their authors' data archiving by implementing "submission integration," by which the journal manuscript submission system interfaces with Dryad. In a nutshell: the journal sends automated notifications to Dryad of new manuscripts, which enables Dryad to create a provisional record for the article's data, thereby streamlining the author's data upload process. The published article includes a link to the data in Dryad, and Dryad links to the published article. See complete documentation of this process here.

Dryad is both a repository and an organization. The organization provides a forum for all stakeholders to set priorities for the repository, participate in planning, and share knowledge and coordinate action around data policies. Members include journals, publishers, scientific societies, funding agencies, and other data centers. Dryad is in in the process of becoming a non-profit registered in the US; for more information see Governance.

As part of its commitment to sustainability, Dryad participates in the DataONE network (the Data Observation Network for Earth,, and is actively developing partnerships with other international data networks and scholarly publishing organizations.

Grant funding for Dryad is described here, and participants in the development of the repository are listed here.
