A sources sought (often capitalized as Sources Sought) notice is used by agencies of the government of the United States to solicit interest in a project under consideration by that agency. They are not requests for proposals or invitations to bid; sources sought come earlier in the procurement process.Bierlein, J. F. (2017)
