Data libraries for physics and chemistry

There are several ways to identify specialized repositories.

• We have preselected a list of discipline-specific repositories for Physics and Chemistry, where data can be both searched and deposited.
• There are also a significant number of warehouse where data can be consulted, even if you are not associated with the institution or the project. Go to this page to explore them.

To broaden your search, try the directory Re3data.org (Registry of Research Data Repositories), created in 2012 and financed by the German Research Foundation. In April 2020, it referenced 2,487 repositories for all fields. Amongst them, 204 are classified as chemistry repositories and 289 as Physics repositories.
That may seem like a lot, but the real available choice is not always as wide as it seems. Some repositories are for niche sectors (such as the repository specialized in data on the preservation of zebrafish in the form of frozen sperm, yet classified as a chemistry repository). Others require institutional affiliation for data consultation, such as the Imperial College of London repository.

Each platform is represented by an icon, a sort of identity card of the repository. The blue icon indicates that that the repository provides relevant identifiers (DOI). The red icon indicates that the repository meets quality criteria (certification).

There are other international repositories such as Repository Finder, OpenDoar (see the filter datasets) and Fairsharing.org.
