Placing the data associated with your research in an online repository is a great way to help others become aware of, and use, your research. Many kinds of data (including datasets, graphs, software scripts, videos, slide presentations, and more) can be posted to a repository. Most online repositories report back on the number of times your data has been viewed and downloaded, demonstrating its impact on other researchers.
Data Citation Index
A single point of access to research data from over 500 repositories across disciplines and around the world. The Index "provides a centralized view of data sets and studies available globally and facilitates an easy way for researchers, librarians, and funding organizations to directly access the primary material." (Description from Thomson Reuters). Provides times-cited information for the data sets and studies.

While there is no cost to researchers to download and use the data in the repository, there is a charge for submission of the data (some publishers may cover some costs).
