The Almanac of American Politics is a reference work published biennially by Columbia Books & Information Services.[2] It aims to provide a detailed look at the politics of the United States through an approach of profiling individual leaders and areas of the country. The first edition of the Almanac was published in 1972. The National Journal published biennial editions of the Almanac from 1984 through 2014.[3] In 2015, Columbia Books & Information Services became the publisher.[4]
Michael Barone deserves mention here as well for being the editor of this for so long.
