The Plum Book, published by the Senate Committee on Governmental Affairs and the House Committee on Government Reform alternately after each Presidential election, lists over 7,000 Federal civil service leadership and support positions in the legislative and executive branches of the Federal Government that may be subject to noncompetitive appointment, nationwide.
Data covers positions such as agency heads and their immediate subordinates, policy executives and advisors, and aides who report to these officials.

The Prune Book, published by the Council for Excellence in Government, serves as a resource for presidential appointees. It describes the positions appointees hold and the challenges they face. The books are distinguished by job profiles that give firsthand insight into such complex realities as managing the federal government for results and the appointments process itself.

Who's Who in the Federal Government, a website published by the University of Memphis, provides biographical and other information about key officials in the Executive, Legislative and Judicial branches of the Federal government.
