Research Data Management: Subject Repositories & Sharing Data

Sharing Data

Why publish your data in a repository?

You can share your data easily by emailing it to requesters, or posting it to a website, Google, Amazon or Microsoft. Unfortunately, this method of sharing makes it difficult for people to find your data. Depositing your data in an archive will facilitate its discovery, preservation, and citation. The Online Registry of Research Data Repositories is a good place to start.  Search it by topic or  Browse by subject, content type, or country.

Data Created at Caltech (Any Discipline)
