This site was recently launched by the Federal government to serve as a single online source to search for all Federal grants. Grants.gov encompasses over 900 grant programs offered by the 26 Federal grant-making agencies which award over $350 billion annually. University personnel are NOT to apply for grants directly through Grants.gov; but must work with the Office of Sponsored Projects Administration on all grant applications, including electronic applications.
