About Citing AGU Articles

Updated 28 September 2005

How to cite an AGU article

The citation, which is displayed prominently below the abstract in AGU articles, includes the following elements:

Author(s), Year of publication (in parentheses), Title of article, Name of journal, Volume number, Citation number, Digital Object Identifier (DOI).
 
Example:
Adrian, M. L., D. L. Gallagher, and L. A. Avanov (2004), IMAGE EUV observation of radially bifurcated plasmaspheric features: First observations of a possible standing ULF waveform in the inner magnetosphere, J. Geophys. Res., 109, A01203, doi:10.1029/2003JA009974.

What is a citation number?

Citation numbers are
     •  assigned at the time of publication
     •  sequential within each issue or within each subject area/subset

The citation number format was revised in 2004 to improve the Institute of Scientific Information (ISI) citation tracking on the individual article level. The citation number format is shown in the example above as A01203:
     •  "A01" is the journal, in this case, JGR-Space Physics, and issue number.
     •  "2" is the subject area/subset designator, in this instance the Magnetospheric Physics subset (SMP).
     •  "03" is the order in which an article is published in the subset in this issue.

Special section and Theme articles are designated with a letter in place of the subject area/subset digit. AGU publishes these articles online as ready and then assembles the collection for a future print issue. See a listing of AGU Special Sections and Themes.

What is a DOI?

The Digital Object Identifier (DOI) is composed of the international identifier assigned to AGU, 10.1029/, and the article number assigned to each manuscript at time of submission. The DOI allows linking of online articles, both within AGU and with other publishers. Authors can provide the DOI of their articles to others from the moment of acceptance. Science, Nature, and many other publications are encouraging the inclusion of the DOI in citations.

How to find an AGU article in print

Citation numbers appear on every page of an article and the range of citation numbers appearing within each printed issue is printed on the spine of the journal. To find an article in the print, the citation number can be used to identify the journal, issue number, subject area/subset designator, and order within the subject area/subset. See above for an example and an explanation of these elements. The table below lists subsets and categories and their currently assigned order within the print issue.
