The Attorney General's Manual on the Administrative Procedure Act was published in 1947 in response to requests to the Attorney General's office for advice on the meaning of various provisions of the Administrative Procedure Act that was signed into law on June 11, 1946. The manual while not exhaustive was intended "as a guide to agencies in adjusting their procedures to the requirements of the Act."

An electronic copy of the manual can be obtained from the Office of Administrative Law Judges at http://www.oalj.dol.gov/public/apa/refrnc/agtc.htm. The OALJ Web page has other Administrative Procedure Act resources such as the Manual for Administrative Law Judges, selected provisions of Title 5, U.S.C., and OPM Regulations.
