The Annual Review of Earth and Planetary Sciences was first published in 1973 by the nonprofit publisher Annual Reviews. The goal of the editorial committee was to produce critical review articles that condensed a large volume of research into a final product usable by students, specialists, and non-specialists. In the late 1990s it began publishing materials electronically. Format changes in 2006 included a simplification of the formatting, inclusion of definitions in the margins, more color, and expansion of supplementary materials, such as videos, in light of increasing access via the internet. The size of individual volumes has grown over time: the volumes published in 2000, 2007, 2012, and 2013 were each noted at time of publication to be the largest-ever volume produced by the journal by page count or number of articles. As of 2020, it was published both in print and electronically. Some of its articles are available online in advance of the volume's publication date. It defines its scope as covering significant developments in the field of planetary science, encompassing earth science. Specific subdisciplines included are climatology, environmental science, and the history of life. Each volume begins with a prefatory chapter of the biography or autobiography of a notable scientist within the field. As of 2023, Journal Citation Reports lists the journal's impact factor as 14.
