A special feature of this invaluable book is the Sources of Information section, which lists addresses and telephone numbers for each agency for employment, contract and grant opportunities, publications, films, and other services available to the public.
In addition, the volume contains agency organizational charts, a list defining commonly used Federal abbreviations and acronyms, and a detailed section on Federal agencies that have been terminated, transferred, or changed in name since March 1933.
The Manual has been compiled and published by the Office of the Federal Register of the National Archives and Records Administration since 1948.
