The evolution of Eos

As you hold in your hands, or perhaps read on a screen, the first 2007 issue of Eos , I would like to tell you a bit about how this, AGU's first publication, got to be what it is today. It is and has always been a publication for all the members. Eos, Transactions, American Geophysical Union , at the top of the front page of your newspaper, is both a short pedigree and a formal title. Transactions, American Geophysical Union , first published in 1920, contained the proceedings of the first annual meeting of AGU and reports of the then seven sections. Transactions continued as an annual volume through 1944, frequently in multiple parts, and a few times in the 1920s did not appear at all. In its first 25 years it covered an increasing suite of AGU‐related meetings.
