Sharing data is an important part of science (e.g., see APA discussion). It's also often useful to be able to have access to datasets when teaching students how to analyse data in the cognitive sciences.

• What online data repositories for research are available in the cognitive sciences (e.g., psychology, psychiatry, cognitive science, etc.)?

Ideally, it would be good to include:

• a link to the repository
• an overview of the size of the repository
• the disciplinary content of the repository
• whether there are restrictions on access and use
