GovSpeak – A Guide to Government Acronyms & Abbreviations: “This guide lists acronyms and abbreviations commonly used by the United States federal government. Each acronym is defined and links to the home page (or best alternative) of the identified department, agency, office, program or publication. While Appendix A of the U.S. Government Manual provided the foundation of GovSpeak, this expanded list includes hundreds of acronyms not included in that publication; most have been discovered by manual reviews of department websites. Links are checked and updated monthly.”
