Both Grants.gov and the Federal Register house announcements for competitive grants throughout the government.  The former allows the potential applicant to electronically search and apply for competitive grant opportunities, while the latter is the official daily publication for rules, proposed rules, and notices of Federal agencies and organizations, as well as executive orders and other presidential documents, throughout the Federal government.  The Federal Register is an actual daily publication and every Federal agency that is submitting a request for application (RFA) or a request for a contract (RFP) must publish it in the Federal Register (it is accessible via the internet).
