Principles of Federal Appropriations Law (Red Book)
GAO's Principles of Federal Appropriations Law serves as a detailed fiscal law guide covering those areas of law in which the Comptroller General renders decisions. The Red Book describes existing legal authorities to illustrate the principles discussed, their application, and exceptions.
GAO is currently working on the third edition of the Red Book. GAO will not revise Volume III of the second edition, as it deals with functions that were transferred to the executive branch by the General Accounting Office Act of 1996 (Pub. L. No. 104-316).
