The American Geophysical Union has just made all its journals open, subject to a two year paywall on its previously non-OA titles…

Starting 1st May [2014], all AGU journal content from 1997 to content published 24 months ago will be made freely available. This change will apply to all articles and supplementary materials from journals that are not already open access, as well as AGU’s weekly newspaper, Eos. It currently represents more than 80,000 journal articles and issues of Eos. Additional content will continue to become open every month, on a 24-month rolling cycle.

Eos and all but three journal titles are published with Wiley (which means they can’t be indexed by JURN, since Wiley jumbles paywall and open content on undifferentiated URLs). Of the non-Wiley titles, Earth and Space Science has yet to publish an issue. Earth Interactions (interactions between the lithosphere, hydrosphere, atmosphere, and biosphere in global context) is published via the American Meteorological Society. Nonlinear Processes in Geophysics is published with Copernicus Publications. These latter two have been indexed by JURN.
