The journal Earth Interactions is published in partnership with the American Meteorological Society (AMS) and the Association of American Geographers (AAG). In addition, International Journal of Geomagnetism and Aeronomy is no longer published and AGU distributes Chinese Journal of Geophysics and Nonlinear Processes in Geophysics. Many of the journals have high impact factors, with Paleoceanography having the highest within paleontology and Reviews of Geophysics the second highest within geochemistry and geophysics as of 2010. AGU has also been publishing books for more than 85 years. AGU has also partnered with societies to publish: Chinese Journal of Geophysics, with the Chinese Academy of Sciences Earth and Planetary Physics, with the Chinese Geophysical Society Earth Interactions, with the American Meteorological Society Nonlinear Processes in Geophysics, with the European Geosciences Union Interpretation, with the Society of Exploration Geophysicists The Leading Edge, with the Society of Exploration Geophysicists AGU co-published (along with the AMS and the AAG) its first electronic journal, Earth Interactions, in 1997. It started its own electronic journal, Geochemistry, Geophysics, Geosystems, in December 1999. It made a full transition to electronic publishing in 2001. For all its journals, the electronic version became the publication of record. This was accompanied by a new identification scheme for articles that entirely did away with sequential page numbers. Instead, each article had a digital object identifier (DOI). As an example, 10.1029/2001GL014304 consists of the publisher identifier (10.1029), the year (2001), the journal code (GL), and an article number (014304). This new system was met with complaints from libraries and scientists. The article numbers provided no clue for libraries to find an article in printed versions, and even scientific databases were not set up to handle DOIs. AGU officials claimed that the problems were a temporary cost of being a frontrunner, but did retroactively assign each article a four-digit article number. In 2012 the journals and books, including over one and a half million pages of legacy content, were transferred to the Wiley Online Library. John Wiley & Sons were recognized for this work with the IT Project Team of the Year Award at the UK IT Industry Awards for 2013. Five AGU journals are open access only:
