In the United States we have administrative and legislative codes. A legislative code contains the statutes organized by the subject matter. Each topic is a title. Administrative codes contain regulations created by government agencies and each title reflects the agency that created. Title 47 of the Code of Federal Regulations was created by the FCC and deals with communications.
You can find Notices of Proposed Rule Making in the Federal Register, which can be searched in Nexis Uni. It can also be searched at the U.S. Government Publishing Office website.
